These specimens show that Ramsay's Perameles torosus f, 

 described from Rockingham Bay, X. Queensland, should stand as 

 a species distinct from /. iniacrourus Gould, with which it was 

 united in the Catalogue of Marsupials. 



All of them are much larger and more heavily built than the 

 type of /. macrourus^ a character that is very evident in the size 

 of the skulls. The following are the average skull dimensions of 

 6 adult males, compared with the type skull, which is also that of 

 an adult male.
