Tlie larval stage of the parasite, Habronema muscae has been 

 met with in Stomo.vi/.'! calcitrans aud Musca domestica in Sydney, 

 and in the latter species in Brisbane. The larval form does 

 not seem to have been previously recorded from Australia. 

 Ransom has recently shown that //. inuscae infests the stomach of 

 the horse. A larval worm resembling the above species occurs 

 in the head region of the common ' cattle fly ' {Musca vetustis- 

 sima) frequenting especially the eyes of cattle in Queensland. 



As a result of examining a large series of rat fleas, small coiled 

 nematode larvae (Afjavionenm sp.) were detected in a goodly 

 number of Xenopsylla clieopis and, once, of Ceratophyllns 

 fasciatus, all the parasitised fleas coming from Sydney and 

 district. So far as the author is aware the presence of larval 

 nematodes in fleas has not been previously recorded. From one 

 to six of them have been found in the body cavity of a single 

 X. cheoijis. Usually the parasite was closely and spirally coiled, 

 and sometimes enclosed by a relatively thick cyst. The whole 

 larva resembles Ihihronema muscae, and the author therefore 

 considers it to be a young form of a Sjnroptera (sensu lato). As 

 the species of Sjjiroptera which infests rats and mice in Australia 

 is ,S'. ohfusa, it is quite likely that the larvae under review belong 

 to this species. 



The cysticercoid stages of Ilymenolepis diminuta and //. 

 vrurina were found in X. clieopis and C. fasciatus, as many as 

 nine cysticercoids of H. murina being detected in a rat flea of the 

 latter species on one occasion, but usually only one larva is 

 present. On another occasion three cysticercoids of the same 

 species were found in an X. cJieopis from Mus decumanus.
