may occur in the pharynx and larynx, and have even been found in 

 sheep in the bifurcation of the trachea down to the large bronchial 

 tubes. This often occurs after the death of the host, but probably 

 never does so in the living animal. In antelopes several larvae of 

 different species are usually fomid at the same time. The larvae of 

 Oestrus, Gedoelstia, and Kirkioestrus are found only among the hollow- 

 horned ruminants, those of Rhinoestrus among the equines, pigs and 

 hippopotamus, while those of Cephalopsis are peculiar to the camels. 

 Information as to the different species and their respective hosts is 

 given in detail in a table. 



The mode of nutrition of these larvae is not well known, but it is to 

 be supposed that they feed on the mucus of the passages in which they 

 are found. The importance of breeding them is emphasised, though 

 hitherto all attempts to rear them to the adult stage in captivity have 

 failed. The adult flies will not feed or pair in captivity. 



An account is given of the organism, Herpetomonas oestrorum, which 

 parasitises these larvae [see this Review, Ser. B, iii, p. 146]. Six larvae 

 of Rhinoestrus nivarleti, E,. and B., taken from the same individual of 

 Potamochoerus porous, L., were all parasitised by a flagellate closely 

 resembling and perhaps identical with this. 



A key to the genera of the Oestrinae is given and descriptions with 

 discussions on synonomy, hosts, and geographical distribution of the 

 following species : — Cephalopsis titillator, Clarke, Oestrus ovis, L., 

 0. aureoargentatus, R. and B., 0. variolosus, Lw., 0. macdonaldi, Ged., 

 Rhinoestrus nivarleti, R. and B., R. hippopotami, Griinb., R. purpureus, 

 Brauer, R. phacochoeri, R. and B., Gedmlstia cristata, R. and B., 

 Kirkioestrus surcoufi, Ged., K. hlanchardi, and K. m.inutus, R. and B. 



A bibliography of 46 works is given.

Four principal zones, where various species of Glossina are prevalent, 

 can be roughly defined from south to north in the Ivory Coast. In the 

 most southern zone G. palpalis and G.fusca are predominant ; the next 

 zone is characterised by the presence of G. pallicera, while G. medicorwn 

 and G. nigrofusca also occur, although their boimdaries are not so 

 clearly defined as in the case of G. pallicera ; in the third zone G. longi- 

 palpis predominates, and in the fourth, G. tachinoides. These zones 

 only indicate the predominance of the given species and must not be 

 considered as forming definite limits for the occurrence of any one of 

 them.

In the dissemination of plague in South Annam (Indo-China), there 

 are four species of rats which play an important role ; these are the 

 small domestic rat, which is probably a new species, the sewer rat 

 (probably Mus decumanus), the rice-field rat, and the musk-rat, which 

 is not a rodent, but an insectivore, probably Crocidura murina, L. ; 

 all of these, except the domestic species, are heavily parasitised by
