730 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Hsematozoa in Guiana.* — E. Brhnont describes some Hasrao- 

 gregarines from a tortoise and several snakes, a species of Hsemoproteus 

 m a bird of prey (Urubitinga), and Trypanosomes in another bird 

 (Catharista), Trypanosomes in the agouti and a monkey, Trypanosomes, 

 along with Endotrgpanum schaudinni, in the two-toed sloth, and species 

 of Microfilaria in four mammals. 



Intestinal Flagellates of Amphibians.t — A. Alexeieff has notes 

 on the occurrence of Hexamitus intestinalis Duj. {Octomitus dujardini 

 Dobell), Octomitus sp., Trichomonas batrachorum, Bodo lacertce, Mono- 

 cercomonas bufonis, Giardia agilis, Treponema agilis, all in Ampbibians 

 indigenous to France. In frog tadpoles he found a new and large form 

 Macrostoma caulleryi g. et sp. n. 



Spirochsets of African Fowls.}— E. Brumpt records Spirochseta 

 nicollei sp. n. from Tunisian poultry. Three other species are known : 

 S. gallinarum Stephen and Christophers (carried by Argas persicus) from 

 Somalilaud, etc., 8. neveuxi Brumpt, from Senegal, and S. anserina from 

 tbe Caucasus. 



Alleged Sporozoa.§ — L. Leger and 0. Duboscq discuss the alleged 

 Sporozoon, Rhabdospora thslohani Laguesse, said to be common in many 

 fishes, and point out that a rod-like or rhabdite arrangement of secretions 

 in glandular cells has been mistaken for the presence of intracellular 

 parasites. 



Microsporidian inside Gregarine.||— L. Leger and 0. Duboscq de- 

 scribe Perezia lanicesterise g. et sp. n., a Microsporidian which infests the 

 Grregarine LanJcesteria ascidise Lank, usually found in the intestine of 

 Ciona intestinalis. The Microsporidian is not found in tbe tissues of the 

 Ascidian ; it occurs only in the Gregarines that are free in the gut. 

 Eacb individual gives rise to a single pansporoblast with two spores. 



Sarcosporidian in Gecko.^f— A. Weber amplifies Bertram's descrip- 

 tion of Sarcocystis platydactyli, which occurs in the muscles of the gecko. 



Hsemogregarines in Snakes.** — A. Laveran and A. Pettit bave 

 found Hajmogregarines in Pituophis melanoleucus and two other Mexican 

 snakes. They describe in particular Hsemogregarina pituophis sp. n. 

 The cysts of these snake parasites show remarkable resistance ; their 

 membrane is very impermeable ; some were found in good condition in 

 the rotten liver of a snake that had been dead for twenty days. 



Haemogregarine of Python.ft— A. Laveran and A. Pettit describe 

 Hsemogregarina sebai, very abundant in the blood of Python sebai, from 

 Senegal.
