On a Ciliate hifusorian parasitic in the Blood of Carcinus msenas. 

 By Dr. G. Cattaneo.

 {Anojilophrya branchiarum) in the branchial lamella) of Oammarus 

 pidex (Zeitschr. f. wiss. Zool. Bd. iii. p. 486). In 1855 Balbiani

 aquatictis, and remarked that this was the first example of a para-

 He proposed for it the name of Anoplophrya circvlans (Rec. Zool. 

 Suisse, vol. ii.). 



In May of the present year the author was engaged in the inves-

 this purpose examined many examples of Carcinus mcenas, during
