128 AUSTRALIAN FRESHWATER FLAGELLATES, 



Lepocinclis Steinii Leminennann. 



This species has been erected by Lemmemiann (Das Plankton schwedischer 

 (lewasser, p. 123, notes) to include Stein's two figures of Lepocinclia {Chloro- 

 peltis) uvum (T. xix., f. 47, 48) which are too slender to be typical of that 

 species. Stein, in his explanation of the plates, considers these as representing 

 Euglena zonalis Carter, but Kent's iigure of the latter (Infusoria, T. sx., f. 58, 

 after Carter) seems to forbid this identification. I do not know this 

 species, which appears to be an oval form, ftiiely striate longitudinnlly. liaving 

 some connection witli the next form. 



Var. suecica Leramermann. (PI. vi., fig.l). 



Long. Corp. 2(i, !at. 11; lat. ap. 3, long. caud. ad 3ft. Casino (189). 



6'/. Lemmermanu, I.e., p. 123, T. i., f. 20. He gives the size as 24.5 — 'IGft. 

 long, and 9.5 — 12^ broad. According to his figure the membrane is finely 

 striate longitudinally with a slight spiral twist. 



(?) Lepocinclis sphagnicola Lemmermann. (PI. vi., fig. 2). 



Long. Corp. 30—32, lat. 12; lat. aj). 3ju,. Botany (109); Guildford (114); 

 Lismore (197). 



Founded on a form figured Ijy O. Zacharias (Forsch. d. biol. Stat. z. Plon, 

 X., p. 259, T. ii., f. 17) as L. fusiformis (Carter) Lcmm. 1 have not seen a 

 figure of this species and therefore am not at all certain about the identification 

 of our specimens. The author ( op. cil., p. 124) describes it as oval with collar- 

 shaped, produced anterior end, and distinctly ])rojecting (?) hyaline hinder end. 

 33^ long and V2fi broad. Tiiese dimensions and specifications seem to suit 

 our forms very well. 



Lepocinclis cymbiformis, n.sj). (PI. vi.. fi^-s. 3, 4). 



Forma cymbiformis, lateribus nunc deplanalis nunc arcuatis. sursum 

 modiee producta truiicata, interne acuminata. 



Long. 30—34, lat. 8—11; lat. ap. c. 3;u,. Lismore (225). 



This species includes certain somewhat irregular boat-shaped forms, sides 

 eitlier flattened or arched; body a little i)i'o(Uiced above, truncate; acuminate 

 behind. Membrane striate longitudinally/ 



Lepocinclis capitata, n.sp. (Pi. vi.. figs. 5, li). 



Forma anguste fusiformis, superne et inferne paene aequaliter attenuata; 

 anteriore producta truncata, maxime capitata; postice in caudara brevcm 

 aeutam protracta. Membrana per longitudineni costata, costis c. G — 8 visibilibus. 



Long. 45—60, lat. 10—14, lat. ap. 4^. Botany (92, 142); Botanic Gar- 

 dens, Sydney (150) ; Lismore (225, 2()0, 299). 



A very pretty and distinct species characterised l)y its slender, regularly 

 fusiform body, produced above into a tnincately-rounded capitate prominence, 

 and below into a short tail which continues the lines of the body. The meui- 

 biane is costate longitudinally, (i — 8 costae showing. 



Lepocinclis cx>stata, n.sp. (PI. vi., tigs. 7, 8). 



Forma lat*-elliptica. fere ovalis; sursum Icvissimc deplanata, baud producta; 

 inferne cauda brevissima triangulari praedita. Membrana co.stis 8 — 10 per 

 longitudinem dispositis urnata.
