 have never seen the living animalcule. Leinmermanu gives long. 2'^. lat. mut.

Cryptoraonadineae. 



Genus C li i- l o m o x a s Elirenberg. 



Chilojionas PAiLviiKfiUM Elir. (PI. ii., tigs. 19 — 22). 



Found in s\\am{) waters almost everywhere; it seems to me very probable 

 that it is a small saprophytic torm ol Cryptumonas; it has the same series of 

 shapes as Cryptumonas ovata. 



Cell long. c. 30, lat. c. 10/i.

Senn (Flagellata. p. 169) remarks on the variability ol' the chromatopliores 

 in this genus and it is particularly noticeable in this species. I have noted the 

 following colours : — Pale nut-brown, deep nut-brown, brownish-green, greenish- 

 brown, yellow-green, pale chluropliyll green, deep chlorophyll green. Almost 

 always to be found in swamp waters, but never in great ijuantities. 



Cell. long. 25—40, lat. 10— 18,x. 



Cryptomoxas ampulla, n.sp. (PI. ii., %. 24). 



C'ellulae (luam in C. ovata majores, longe ovales, lateribus arcuatis; pone 

 rotundatae, fronte oblique trun<'atae ct infra, uno latere, valde excavatae. Chro- 

 matophoris fusco-viridibus. 



Cell. long. 50, lat. 23, ap. lOi^. Lismore (327, 337). 



A larger form than C. uvata and more nearly oval in shape, rounded behind, 

 sides arched, obli(|uely truncate in front. Below the lower edge of the truncate 

 l)ortion there is a deei) excavation, making the cell appear somewhat irregularly 

 tliisk-shaped. Chromatopliores Ijrownisii-green, more green than brown, iiowever. 

 The interior seems to l)e differently arranged from ('. ovata also, ius there is a 

 wide bag-shaped j)harynx, longitudinally striate with rows of minute punctuhi- 

 tious. Not common. 



CKYPTOMOXA.S maxima. U.sp. (PI. 



fig. 25). 



Cellulae maxime, plus minus oblongae, fronte modice atteiiuatae, postice 

 rotundatae; uno latere aequaliter arcuato, altero juxta ai>ices intcrdum infla- 

 tione instructae; chromatophoris i)leruni(iue fusco-viridibus. 



Cell. long. 50—70, lat. 22— 28;x. 



Botany (142) ; Lismore (261,327, 337). 



Double the size of C. ovata and mucli more irregular in shape, it is ol)l(ing 

 in general outline, somewhat narrowed back and front, especially the latter. 

 One side is fairly regularly arched, but the other has often a slight protuberance 

 near each end. The cliromatoi)iiores are generally lirownish-green. but i have 

 noted them pale-green and yellow-green.
