314 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Indian crow. They appear to differ from the only Trypanosoma hitherto 

 described as occurring in birds, and from each other. 



Coccidia in Lamellibranchs.jl — L. Leger describes a monozoic 

 parasite which is extremely common in renal epithelium, branchiae, etc. 

 of mussels at Calvados. It occurs also in Mactra, Donax, Tapes, and 

 Tellina. The oyster is not infected by it. The branchiae may be riddled 

 by the ripe sporocysts, yet apparently without fatal effect. The parasite 

 belongs to the genus Nematopsis, and appears to be closely related to 

 the form inhabiting the mantle of Solen. 



Piroplasma donovani.f — A. Laveran and F. Mesnil give some 

 details in regard to this parasite, found by Leishman and Donovan in 

 the blood of the spleen of individuals from India, suffering from 

 irregular remittent fever.
