canis, Curt., and Pidex irr items, L, It is admitted that the proboscis 

 of these fleas is incapable of permitting the passage of the eggs of 

 D. caninum, but the author has found that the flea larva can swallow 

 the egg, which, on arrival in the intestine, at once hatches and the larva 

 penetrates into the general body cavity. 



Hymenoleqyis dhnvnnta, Rud., a Cestode of the rat and of man, has for 

 intermediate hosts, Pyralis {Asopia) farinalis, L., both the caterpillar 

 a,nd adult moth ; the earwig, Anisohbis annidi/pes, Lucas ; the 

 Tenebrionid beetles, Akis spinosa, L., and Scaurus striatus, F. ; and 

 the fleas, Cemtophyllus fasciatus, Bosc, XenopsyUa clieopis, Roths., 

 C canis and P. irrilmis. These fleas also become infested in the larval 

 stage. In the case of Hymenolepis nana, v. Siebold, the intermediate and 

 final host are the same. Rats and mice are easily infested and the 

 rat-fleas, X. clieopis and C. fasciaius, are said to be hosts, although the 

 author was never able to infest these species.

During the course of this campaign no epidemic of any importance 

 was imported into Kamerun, in spite of the constant relations with the 

 ports of West Africa and Europe. Malaria is present throughout the 

 country, but rarely attacked natives with any severit}^ though it was 

 serious among the European troops. Black-water fever, which attacked 

 Europeans only, caused many deaths. Trypanosomiasis was rare 

 among either Eiuropeans or natives, although Glossina. paJpalis abounds. 

 The effects of the campaign on the development of the disease in the 

 colony will not however become apparent until later. A few cases of 

 infestation by Filaria loa were met with.

This paper contains a complete record of the distribution of Ixodes 

 {EschatocepJmlas) vespertilionis, Koch, and of Ixodes hexa'gonus, Leach, 

 together with notes on the biology of both species. Collections of 

 I. vespertilionis show a considerably greater proportion of males than of 

 females, nymphs, or larvae. Adult males have never been found as 

 parasites on the bat, but always freely on the walls of caves. This 

 fact indicates that in tlie males of this sjjecies parasitism is limited to 

 the larval and nymphal stages, but occurs in the females in all stages. 

 The laivae, which emerge either on the ground or on the walls of caves.
