and by appropriate colouring of figure in plate respectively : — 

 " gewundenes Augenthierchen," " fuscescente vijidis," " a couleur verte 

 brunatre," and brownish-green. The specimens seen by me were all 

 bright green — equal in that respect to E. viridis, which Ehrenberg dis- 

 tinguished as " griines Augenthierchen," " Euglene verte .... 

 couleur verte, hyaline aux deux bouts," and again, " Colore viridis 

 utroque fine hyalina." The name E. viridis, by the way, is also 

 credited to PoggendorfE's publication, which preceded that of Ehrenberg 

 by eight years. Ehrenberg gives size as follows: — " Grosse 1/20 bis 

 i/io Linie beobachtet," which (101-203 /<.), compared with an average 

 size of the Melbourne form, makes the latter appear to be of less than 

 medium size — viz., total length, 120 fi. ; caudal attenuation, 13.6 fi. ; 

 breadth when extended, 16.2 f.i. ; amylaceous granules, 20.4 x 10 n. 

 and 20.4 X 8.5 /«. ; stigma, 3.5 (PL v., fig. 9). 



Trachelomonas, sp. ? 



Common in all pools. To be further examined and referred to in a 

 later paper.

assumed by this species in contortion, and to which the specific 



name mav be due.
