When exuvia of the amphipod Marinogammarus obtusatus were examined, they contained swimming trophonts whose characteristics revealed by Chatton–Lwoff stains describe a new species of Gymnodinioides. Its unique characteristic is the retention in the trophont of a polykinety similar to the falciform field of the tomite, the non-feeding, migratory microstome stage common to apostome genera. The trophont's anterior pattern of kineties also resembles that of the tomite. Speculations that speciation in Gymnodinioides may result from isolation on different hosts, changes in the internal feeding apparatus, delays or mishaps during morphogenesis, or habitat changes affecting the host must consider the case of G. pitelkae. The tomite may not respond to the signals from its premoult host to change to the macrostome infraciliature although the feeding apparatus is formed.}, number={2}, journal={EUROPEAN JOURNAL OF PROTISTOLOGY}, author={Bradbury, PC}, year={2005}, month={Apr}, pages={85–92} }

China), have been examined in vivo and with silver nitrate and protargol impregnations. A comparison of the two forms reveals marked differences in structure sufficient to separate the two morphotypes into two species. Euplotes parawoodruffi n. sp. (syngen 1 of E. woodruffi) is characterized by a strongly arched dorsum, regular double-eurystomas type silverline system, an adoral zone of ca. 80 membranelles extending over 4/5 of the cell length; 9 frontoventral, 2 marginal, and 2 caudal cirri; marine/brackish biotope; macronucleus irregularly T-shaped. Its T-shaped macronucleus with a short right arm differs from that of E. woodruffi, in which the right arm is longer than the left. The general body shape of E. parawoodruffi, broad anteriorly and tapering posteriad, differs from the ovoid shape of E. woodruffi. Its domed dorsum without longitudinal grooves differs from the flattened dorsum with shallow grooves of E. woodruffi. The presence of a longer AZM formed of consistently more membranelles and the absence of a pre-oral pouch (an invagination on the dorsal wall of the buccal field anterior to the cytostome, always present in E. woodruffi) further separates E. parawoodruffi from the latter.}, number={4}, journal={ARCHIV FUR PROTISTENKUNDE}, author={Song, WB and Bradbury, PC}, year={1997}, month={Dec}, pages={399–412} }

A species of peritrich that attaches to gills of the skate, Raja erinacea, was identified by its original describer as a member of Caliperia, a genus characterized by having a noncontractile skeletal rod within the arms of its cinctum and by not having the cinctal arms bonded to one another at their tips. Our observations of the living ciliates confirmed by protargol impregnation and electron microscopy revealed that their cinctal arms are linked by a bouton and that the cytoskeletal structure within them has the fine structure of a myoneme. These characteristics place this peritrich unequivocally in the genus Ellobiophrya and it is thus renamed Ellobiophrya brevipes (Laird, 1959) n. comb. Clumps of epithelial cells clasped by the cincta of E. brevipes show damage at their bases but not on their luminal surfaces. The known species of Ellobiophrya are compared for significant structural differences that separate species of this genus.}, number={4}, journal={JOURNAL OF EUKARYOTIC MICROBIOLOGY}, author={Clamp, JC and Bradbury, PC}, year={1997}, pages={374–382} }
 @article{bradbury_song_zhang_1997, title={Stomatogenesis during the formation of the tomite of Hyalophysa chattoni (Hymenostomatida : Ciliophora)}, volume={33}, ISSN={["0932-4739"]}, DOI={10.1016/S0932-4739(97)80052-1}, abstractNote={Summary The functioning oral apparatus of the feeding stage of Hyalophysa chattoni Bradbury, 1966 , arises from pre-existing structures in the tomite that change their form and position during a metamorphosis to the trophont. These structures are the relic of a microstome oral apparatus in the non-feeding tomite. Their origin has been studied during tomitogenesis using Shi's protargol method. In general, this method of silver impregnation confirms the earlier description of tomitogenesis by Chatton and Lwoff, but it reveals significant details concerning the fate of certain transient kineties that form structures which later contribute to the functioning cytostome. Before palintomy, all the kineties of the encysted tomont straighten and become meridional. Nine somatic kineties − x , y , and z (the “oral” kineties), and kinety a , thirteen kineties altogether extend approximately from pole to pole. Kinety a parallels K1. After the first division of the tomont, the kinetosomes of K a multiply in a broad band to the left of the kinety. During subsequent divisions, the kinetosomes in the band assemble into three meridional, transient kineties — K a , K b , and K c . After the last division, each daughter has nine meridional somatic kineties spaced around the body and six meridional ventral kineties crowded between K1 and K9. During tomitogenesis, all the ventral kineties shorten; only the posterior halves of x , y , and z are retained. Kinety x extends a little farther anteriad than y and z . This extension separates from the rest of x and sinks into the cytoplasm where it forms the tuft of cilia on the proximal wall of the developing rosette. The shortened a , b , and c migrate left, anterior to x , y , and z . Both extremities of K a disappear, and the remaining kinetosomes proliferate to form the ogival field, a mid-ventral patch of closely set cilia found only in the tomite. Kinety b disappears leaving behind a barren haplokinety near the apex of the tomite. Kinety c disappears completely, but under the pellicle in the place where it disappears, a microtubule-lined canal, the cytopharynx of the microstome, parallels the ogival field and the haplokinety to the apex of the organism. The last step in microstome formation is the doubling of the anterior portion of kinety 8 and the quadrupling of the anterior fragment of kinety 9 to produce falciform fields 8 and 9 (FF8, FF9), the equivalent of oral polykineties 2 and 1 in other hymenostomes. The oral apparatus of the microstome consists of an anterior haplokinety (paroral), three polykineties (FF9, FF8, and the ogival field), and the cytopharynx. Except for the falciform fields, all these structures originate from kinety a . The falciform fields originate as proliferations of the ends of somatic kineties 8 and 9, indicating that, at least in part, apostomes have telokinetal stomatogenesis. The origin of K a is revealed during the formation of the macrostome. After the tomite encysts on the host, the ogival field disappears completely within hours. When metamorphosis to the trophont begins, the barren haplokinety and the lateral canal migrate posteriad over the ventral surface and then dorsad, establishing the limits of the extended cytostome, a greatly enlarged surface on the trophont. The haplokinety then disappears, and the microtubules of the cytopharynx remain as ribs under the extended cytostome. Falciform field 8 remains unchanged, still a dikinety. The kinetosomal rows of FF9 become disorganized, and paired kinetosomes move over the anterior ventral surface to form the anterior field of scattered kinetosomes characteristic of Hyalophysa . The posterior portion of FF9, losing kinetosomes as it goes, moves across the mid-ventral surface and stops at the left of K1 where K1 makes a sharp angle to parallel the extended cytostome. There the last remnant of FF9 remains as K a in the trophont. It does not function as oral ciliature. It is an anlage for part of new microstomes in daughter cells that will be formed days hence. The microstomes of these daughter cells will be completed at that time by the proliferation of kineties 8 and 9 to form FF8 and FF9. Thus, in Hyalophysa the tomite's microstome is formed in part by a derivative of K9 (K a ) from the preceding generation and completed by proliferation of K8 and K9 from the present generation. Stomatogenesis is telokinetal, but modified by a somatic derivative from one generation carried over to the next.}, number={4}, journal={EUROPEAN JOURNAL OF PROTISTOLOGY}, author={Bradbury, PC and Song, WB and Zhang, LM}, year={1997}, month={Dec}, pages={409–419} }
