THE GENUS TRACHELOMONAS, 



Var. Klebsii mihi. (PI. iv., f.l4). 



Lorica ovata, a f route rotundata, a tergo modice acuminata, 

 oblique striata; coUo nullo. 



Long. 24-26, lat. 18; lat. oris 6 /x. 



Lismore 244, cum prioribus duabus; 245. 



Syn. Tr. reticulata Klebs, Organiz.ein. Flag., 1885, cf. Dangeard, 

 Les Eugleniens, p. 137, f.43. The name 7'eticulata is unsuitable, 

 as probably the type is reticulate also. Stoker' Tr. ohovata, New 

 Frw. Infus., Amer, Philosopli. Soc, 1890, p. 76, f.l3, is also 

 almost certainly a form of this species; if it is really hispid, it 

 might stand as var. Stokesii mihi, the type being just as much 

 obovate. Tt is possible, however, that it is the same as 7V. 

 reticulata Klebs, and the hispid appearance due to pores running 

 through the walls of the lorica. The inner margin of the mem- 

 brane is often very distinct, while the outer edge is extremely 

 vague; the pores then show as fine granules or setae upon what 

 appears to be the surface. 



Trachelomonas caudata var. australica, n.var. (PL v., f.l, 2). 



Lorica ut in forma typica, corpore autem breviore, spinis nullis, 

 membrana aspera. 



Long. 62-96, lat. 18; coll. long. 14-20, 

 lat. 5; caud. long.18-30, lat. max. 4-6 /x. 



Lismore 238. Wyrallah, mere on 

 grass-land. 



This is the nearest I have seen to 

 Stein's Tr. caudata, I.e., PI. xxii., f.39, 

 40. It has an entirely different sur- 

 face, lacking the spines, and the body 

 is shorter in proportion to the total 

 length. Stein's f.40 agrees perfectly 

 in general dimensions, working out 

 at long. 64 (neck 9, body 41, tail 14), 

 lat. 18 J /x. The slender form of the 

 same breadth was found at Wyrallah, alive 

 Trachelomouas.
