The authors in an earlier note described Herpetomonas ctenopsyllae, 

 obtained from Ctenopsylla musculi [see this Review, Ser. B, iii, p. 144], 

 They record in the present note the culture of a flagellate from 

 Ctenocephalus canis, the dog-fiea. The organisms, thus obtained, 

 show a great resemblance to H. ctenopsyllae, but differ in having long 

 flagella which are absent or very short in H. ctenopsyllae. It is hoped 

 to make experiments to discover whether H. ctenocephali is inoculable 

 to mammals.

During the course of experiments on kala-azar in October 1918, 

 the author examined a dog of which the fleas {Ctenocephalus canis) 

 were infected to the extent of 75 per cent, by a species of Leptomonas. 

 No culture could be obtained either from .the marrow of the leg-bones 

 or from the blood. In view of the number of times that fleas have 

 been considered to be connected with the transmission of Mediter- 

 ranean kala-azar, investigations were made upon these flagellates to 

 determine whether they were identical with those causing kala-azar, 

 or definitely distinct from them. The inoculation of a culture from 

 30 fleas into two mice gave a negative result. A pure culture of the 

 Leptomonas from these dog-fleas was obtained, and the flagellates 

 are described. The author is convinced, in view of these investigations, 

 that there is no relation between the Leptomonas isolated by him 

 from the dog-flea and the Leishmania causing canine kala-azar in 

 Tunis. Judging from its form, the species obtained seems to be 

 distinct from the flagellates previously described by other investigators 

 [see preceding paper]. 



In the course of the discussion following this paper, in reply to the 

 question whether in the cultures of Herpetomonas obtained from 

 these fleas there were any cysts identical with those obtained from 

 the rectum or the excreta of these insects, it was stated that there 

 were present in the cultures certain ovoid, non-flagellate forms that 

 might be the equivalent of the cystic forms ; these were however 

 very rare in the fleas examined.

From experiments made to discover whether geckos act as reservoirs 

 of the virus of Oriental sore, it has been found that Tarentola mauri- 

 tanica is infected with Leptomonas in the south of Tunisia in the 

 proportion of 37*5 per cent., but appears to be immune in the north. 

 It would be interesting to discover the limits of distribution of this
