parasitises the buffalo, on a camel in Australia 

 (Nuttall's collection). As Dr. Cleland forwarded 

 specimens to Prof. Xuttall also, it may be assumed 

 with safety that it was these stragglers from West 

 Australia that Neumann had before him. It is a pity 

 that the name of the collector was not indicated, in 

 the case of this interesting find. 



Horse. 



Hoematopinus asini, L. 



N.S.W.— Collected by Mr. A. S. Le Souef. 



Lea (1908, p. 104) mentions the species, but does 

 not state whether it occurs in Tasmania. 



'.Sheep. 



Linognathus ovillus, Neumann. 



N.S.W., South Australia. Not previously 

 recorded from Australia. This parasite has been 

 recognised by one of us as occurring, though rarely, 

 on sheep in certain localities of New South Wales. 

 Mr. Desmond, Government Veterinarian, Adelaide, 

 has recently forwarded the same species for determina- 

 tion, from two widely separated localities in South 

 Austraha. In 1906 Dr. Gilruth (1906, p. 309) met 

 with it in New Zealand and figured it as Hcematopinus^ 

 sp. Neumann later described it as H. ovillus, Gilruth 

 giving a resume of the description in 1908. 



. Rabbit. 



Hcemodipsus ventricosus, Denny. 



N.S.W. This species is now recorded for the 

 first time as occurring in the Commonwealth. Our 

 specimens were collected in Sydney from rabbits sent 

 from the southern district of N.S. Wales. • 



Mouse. 



Though pediculids have been carefully searched 

 for, none have yet been found by us on this host. 



Rats. {3Ius rattus (alexandrinus) and Mus decumanus.) 

 Polyplax spinulosus, Burm. ^ ,., ,.■. 



Recorded from both hosts, from Sydney; by one 

 of us (Johnston, 1910, p. 20), who has specimens from 

 Melbourne and Brisbane also from these two species
