TovoDA (S.)- study of the Organism of Relapsing Fever in Manchuria.

The spirochaete producing relapsing fever in Manchuria and Korea 

 is regarded as different from that causing the disease elsewhere. This 

 strain is already known to be pathogenic to monkeys, and the author 

 has succeeded in infecting the mouse, rat and guinea-pig, though it 

 seems to have less virulence for these animals than the African and 

 European virus. An animal once recovered from an infection with the 

 Manchurian spirochaete is not susceptible to reinfection with the 

 other strains. Lice were recognised as the transmitting agents, though 

 no additional proof of this was obtained.

It has been taken for granted that the mites found on the ears of 

 wild rats are the true carriers of tsutsugamusbi or river fever of Japan. 

 The author states that two species are confused and demonstrates the 

 differences between them, which are mainly concerned with the shape 

 of the hairs, in a series of photographs and drawings. It is pointed 

 out that rats and their parasites are widely distributed over Japan, 

 while the disease is limited in extent.

The species of Anopheles collected in Daito in 1902 by Tsuzuki and 

 believed to be Anopheles {Myzomyia) rossi was also taken in south 

 Formosa by Kishita. who also recorded it under the same name ; it 

 has since been identified as A. (Nyssomyia) ludlowi. At the port of 

 Arito the author collected A. (N.) fuliginosus and A. (M.) rossi, and 

 Morita has reported A. {Myzorhynchus) sinensis from the same locality. 

 In October 1915 Kaw^asaki collected this species, as well as 

 A. (M.) punctidatus and A. listoni. A. sinensis, A. maculatus, A. rossi 

 var. indefinitus and A. tessellatus are common in Formosa. These 

 four have been reported from the vicinity of Hongkong, together with 

 A.jeyporensis, A. karwari, A. maculatus wax. ?, A. minimus, A. mmimus 

 var. ? and A. indiensis [see this Review, Ser. B, iii, p. 141]. Three 

 species of Stegomyia are reported from Formosa : — S. Jasciata, 

 S. albopicta [scutellaris) and S. iv-alha.

Four common species were found in the district of Toeucho. 

 Anopheles sinensis, A. listoni, A. punctulatus and A. willmori, as well
