Stegomyia fasciata, the carrier of yellow fever, in Batoum and Poti, is of 

 special importance. [V. infra.] 



The Report contains suggestions as to the organisation of the 

 antimalarial campaign in Caucasia and for regulations to be observed 

 by the workpeople on the railways under construction.

The author reports that Stegomyia fasciata has been found in Russia, 

 on the Black Sea coast of Caucasia ; he has found large numbers of 

 these mosquitos in Batoum during the investigations conducted there 

 by the Malaria Committee of the Pirogov Society of Surgeons and the 

 same species has been also found in Poti by Dr. Ljachovetzky. He 

 gives a description of the insect and information as to its biology. Stego- 

 myia fasciata is found at Batoum in large numbers in houses, where 

 they attack man mostly in the daytime, but also at night, strangers 

 suffering more than natives ; in the house in which the author lived, he 

 was the only person attacked by the pests. The fact that, according to 

 Clarac and Simond, Stegomyia fasciata is found only between 40° of 

 north latitude and 40° of south latitude, while Batoum Hes on 41*40° 

 and Poti 42-20°, leads the author to conclude that these mosquitos 

 have been imported by foreign steamers into these towns, where they 

 have found favourable conditions for breeding. This view receives 

 confirmation from the presence of these mosquitos only in Batoum 

 and Poti, the only two ports on the coast which are visited by steamers 

 from South America, Egypt and similar countries. Owing to the 

 severe winter in these localities, it is assumed that the mosquitos winter 

 in their larval stage. Investigation on the spot has shewn that in 

 1884 there was a severe epidemic of malaria in Poti, with a high death 

 rate. The author states that the medical records are very incomplete, 

 but he has reason to suspect that some of the cases in 1884 were not 

 malaria, but yellow fever. Owing to the cold weather in this town 

 the disease could not become endemic there, but the presence of these 

 insects constitutes a serious danger to Russia, especially as the trade 

 of those ports with hot countries increases yearly.

Mai de caderas is an epizootic disease affecting horses, mules, and 

 asses in South America, and is also known as : — peste de caderas 

 (Brazil) ; mal de caderas, tumby-baba or tumby-a (Paraguay, 

 Argentine). Discovered by Dr. Elmassian in 1901, the causative 

 parasite was named Trypanosoma equinum by Vosges of Buenos 

 Aires. According to Laurda the disease was imported into 

 the island of Marajo (Brazil), whence it spread as far as the State 

 of Matto Grosso (Brazil). Since 1860, its ravages there have been such 

 as to cause all horses and mules to disappear and to be replaced by 

 cattle, even for riding purposes. At the present time, the disease has 

 greatly extended its range and it occurs in Brazil, Bolivia, Paraguay, 

 the Argentine territories of the Cliaco, Formosa and Misiones, and
