Leptomonas davidi, which parasitises Euphorbia, has Stenocephalus 

 agilis as its primary host, in which development continues up to the 

 saUvary metacyclic forms. Besides these primary hosts, the Lepto- 

 monads mav perhaps be transmitted mechanically by other bugs. 

 In the case of Stenocephalus there are strains with a marked receptivity 

 for Leptomonas davidi, while others display a marked resistance to the 

 infection. This is of importance in view of the objection to the 

 hypothesis of the transmission of Leishmania donovani by bed-bugs, 

 based on the much greater extent of the distribution of Cimex as. 

 compared with that of kala-azar.

An isolated case of Oriental sore is recorded from a locality on the 

 Algiers-Tunis railway, within the zone of distribution of Phlebotomus 

 papatasii. The ground is very broken and covered with the vegetation 

 characteristic of the Mediterranean coast. A rapid search that was 

 made in the outhouses of an inn resulted in the capture of one male 

 and two females of Phlebotomus [Sergentomyia) pernictosus, which is 

 constantly associated with P. papatasii on the Algerian coast.

With reference to the oil trap for fleas described by him [R.A.E., B, 

 X, 101], the author states that a live sheep is quite as practical a trap, 

 as the wool fat asphyxiates the fleas. There may also be a possible 

 toxic action of the fat. It is well to starve the fleas for a few da}^^ 

 before introducing the sheep. These animals are particularly suited 

 for the purpose of clearing such flea-infested buildings as pig-sties, 

 where the oil trap is unsuitable. The pulicidal property of sheep 

 fleeces explains why these animals are free from fleas. It is known that 

 the sheep ticks, especially Rhipicephalus, infest the ear, and the author 

 believes that this place is chosen as a shelter against the noxious action 

 of the wool fat. According to a statement by Dr. Weisgerber, a sheep- 

 skin, even if washed, can serve as a flea-trap, and the natives advised 

 him to use a sheepskin as a bed mat in order to rid himself of fleas. 

 He thinks that the flea is held captive by the hairs.

In a further note on Ornithodorus marocanus, Vclu [R.A.E., B, vii, 

 86] it is stated that this tick was recently captured in hundreds in 

 pig-sties in Morocco underneath palm leaves strewn on the ground
