70 entozoa of rats and mice. 



Catalogue of the Endo-parasites Recorded from 

 Rodents in Australia. 



A list of the helminth entozoa known to occur in 

 rodents in this continent up to 1909 was pul^hshed in John- 

 ston 19106, but no references to literature were given. 

 Since that date a number of new records have been made. 

 The parasites known to infest rats and mice in Queensland 

 are mentioned in my Census (19166). Stiles, Hassall 

 and Crane (1910) have pubhshed information regarding 

 the entozoa of Muridse. 



A tabular statement of the ectozoa found whilst examin- 

 ing rodents in the Bureau of Microbiology, Health Doi:)art- 

 ment, Sydney, during 1909-1911, was published by me 

 (1910c and 19126), the work being continued by Mr. G. 

 Darnell-Smith (Bur. Microbiol, N.S.W., Rep. 3, 1912 

 [1914], p. 19) and Dr. J. B. Cleland (later reports of the 

 Bureau)*. Banks (1910) has given an account of those 

 known to occur in the United States.
