a North African rodent). The new form— i'rijptoplasma rliipkepliali 

 g. et sp. n. — is a cytoplasmic mass, without evident nuclear system, 

 enclosed in a thick shell, outside which there is a hehcoid body which 

 stains like a nucleus, but is not accompanied by any cytoplasm. It may 

 be that the " parasite " represents a combination of two elements — the 

 outer, a host-cell, e.g. a blood corpuscle, reduced to its nucleus ; and an 

 inner, the Protist proper. But the case requires further investigation. 



Blood Parasite of Tarantula.* — Ed. Chatton and G. Blanc 

 discuss Pirhemocijton tarentolse, which they reported in 1014 from the 

 blood corpuscles of Tarentola mauritanica. There are young spherical 

 homogeneous forms with diffuse chromatin, amoeboid forms with 

 condensed chromatin masses of varied shape, large spherical forms 

 with peripheral chromatin particles and a central corpuscle. The 

 interpretation of these three forms must be deferred until more is 

 known. Xo multiplication of the parasite (or parasites ?) was observed 

 in the blood corpuscles or elsewhere. 



Parasitic Protozoa in Spain.! — Fidel Fernandez Martinez takes 

 a survey of the parasitic Protozoa observed in Granada, Malaya and 

 Almeria, and deals in particular with Leishmania infantum and 

 Eatamceba histolytica.
