AnopJirys scircophaga , nov. gen., iiov. spec. 



Body yellowish, oblong, rounded posteriorly, ■with tho rostrum 

 bent laterally into a hook, flexible, with longer cilia than those of 

 the posterior part of tho body {Acineria tncurvata, Diij. ?). Length 

 60 1.1, breadth 15 ;t/. 



The form found by tho author coincides with the generic charac- 

 ters, but ditfers somewhat from yi. sa/Yi)^)7i ?;/,?. specifically, especially 

 in its smaller size, the absence or extreme attenuation of the stria- 

 tion, and its parasitic nature. Hence tho author is led to regard it 

 as a new species, which he proposes to name in honour of Prof. 



Order HOLOTRICHA. 



Fam. EjfcnELTiDJE, Sav. Kent. 

 Genus AxoruRTs, Cohu. 



AnopJirys Magyii, nov. spec. 



Char. Body elongate-oval (^ 35-45 x 10-1:2), rounded posteriorly, 

 with the anterior part pointed and recurved like a rostrum ; ante- 

 rior cilia longer than the lateral aud posterior ; nucleus median and 

 contractile vesicle posterior ; buccal aperture situated beneath the 

 rostrum, and furnished with a circlet of cilia ; the transverse and 

 longitudinal striation not visible or very indistinct. 



Loc. In the blood of Carchnts mcenas. 



Individual differences occur in the size and in the greater or less 

 curvature of the anterior and expansion of the posterior part. From 

 one to five vacuoles containing granules, besides isolated granules. 

 The rostrum is very mobile. The motion of the Infusorian is rapid, 

 continuous, and direct ; occasionally some are seen to stop and 

 rotate around the longitudinal axis. Tho adaptation to a parasitic 

 existence in the blood of the Crustaceans is especially manifested in 

 the aptitude to change its form, narrowing momentarily in order to 

 pass through confined spaces (as is also doiie by AnopJophnja circu- 

 lans, Balb.). "While the AnojiJophnja having no mouth is evidently 

 nourished by the blood-plasma, the AnojyJiri/s, by the movements of 

 the buccal cilia, devours the cells and granules scattered through 

 the blood. Several individuals were seen in transverse segmenta- 

 tion. 



The essentially carnivorous nature of the other known species of 

 Anophrys explains the adaptation of A. JMagc/ii to a parasitic 

 existence. The invasion of the parasite most likely took place 

 through wounds of its host, perhaps at the period of the change of 

 skin ; but the presence of the parasite in only one out of some three 

 hundred Carcini examined, and that one showing injuries, would
