les longs flagellés dont il a été parlé jusqu'ici, existent des états 
intermédiaires: P. pense qu’on a pu regarder ces états comme 
appartenant à un flagellé d’une espèce et même d’un genre dif¬ 
férent de H. muscac domcsiicae. 
L’auteur insite sur l’importance de ces faits pour l’interpréta¬ 
tion de tout ce qui concerne les rapports des Hémoflagellés avec 
les insectes piqueurs. 
Preliminary report on a new piroplasm 
( (( Piroplasma Gibsoni » sp. nov.) found 
in the blood of the hounds of the Madras 
Hunt and subsequently discovered in the 
blood of the jackal « Canis aureus » 
By W. S. PATTOX, M. B., Edin. I. M. S.

Ib : 10 ozs., and her liver, 4 Ibs : 8 ozs ; the latter was congest- 
ed and verv friable. -The spleen was sent up to the Tnstitute the 
next dav, but as it was decomposed T could not examine it mi- 
croscopically. On December 10 tii. the condition of the hounds did

their blood examined, but as I was not at the Tnstitute at the
