XXXVII. — Ophrjocystis Biitschlii, a Sporozoan of a new 

 l^i/pe. By AiMB Schneider ^. 



[Plate X.] 



It is always an ungrateful task to publish an uncompleted 

 work, and powerful motives are necessary to induce one to 

 undertake it. But certain forms appear so curious, the 

 peculiarities by which they are related to other groups some- 

 times render them such valuable rallying-points, and there is 

 often so much scientific interest in knowing them even 

 imperfectly, that to hesitate in such cases would be a mistake. 

 It seems to me that the Sporozoan of which I am going to 

 speak is of this number — that it is important to bring it under 

 the notice of all the specialists whose further investigations 

 it may guide, especially as I do not know when I shall 

 myself have the good fortune to meet with it again, I have 

 made of it the genus Ophryocystisj and I dedicate the species 

 to Professor Butschli, the editor of the Sporozoa in Bronn's 

 ' Thierreich.' 



It is in Blajjs that this Sporozoan lives as a parasite.
