Every month of the year Boophilus {Margaropv.s) annulatiis australis 

 (cattle tick) was found on cattle. The heaviest infestation was in 

 May, June and July. 



Toads received from Barbados in January were infested with Amhly- 

 omma dissimile (reptile tick). 



At St. Croix only three species of mosquitos were found : Stegomyia 

 fasciata {Aedes calopns), Anopheles albimanns, and Ciilex fatigans 

 {quinqiiefasciatus). The control measures used were draining mud- 

 holes and standing water, and spraying septic tanks, etc., with kerosene.

The known facts regarding the different methods by which parasites 

 may gain access to their hosts are here detailed and the discoveries 

 of various authors contributing to the knowledge of the subject are 

 briefly reviewed.

 District, Morocco.] — Bull. Soc. Path. Exot., Paris, xiv, no. 6, 

 8th June 1921, pp. 316-320. 



The occurrence of spirochaetosis in fowls, ducks and geese in the 

 Doukkala district is recorded. The malady may be either acute, 

 rapidly ending in death, or chronic, causing more or less complete 

 paralysis of the lower limbs. It is very probable that there is also 

 a benign form, with more or less complete absence of symptoms of 

 disease. The carrier is Argas persicus, Fsch., which is abundant 

 in all fowl-houses, especially in summier, to such an extent that it 

 is impossible to keep the birds shut up. It would be interesting to 

 discover whether the causal agent of spirochaetosis of fowls in 

 Morocco is the same as that in Algeria.

 specialement de Herpeiomonas larentolac. Procede simple de 

 Culture des Herpctomonas. — Bull. Soc. Path. Exot., Paris, xiv, 

 no. 6, 8th June 1921, pp. 323-326. 



The findings of various haematozoa in the gecko [Tarcntola mauri- 

 tanica) in Algeria and Tunisia by different workers are briefly reviewed. 

 During the summer of 1920 the authors examined 17 individuals of 

 T. matiritanica from various parts of Italy. Trypanosomes were 

 found in seven of these, though only numerously in one, while eight 

 revealed Herpeiomonas. In three cases the former only were found, 

 and in four cases the latter only ; in four cases both occurred together. 

 These Haematozoa frequently escape observation by direct examina- 

 tion ; the cultural method of determining their presence is described.

 he gave the name 0. marocanns, enumerating the characteristics
