often getting togetliei- and forming Avarrens similar to those of 

 rabbits. Tliis species does not seem to occur around Albany. 



" ' Boodee ' of colonists and natives." — G. C. S. 



For nomenclature see below^, p. 773. 



30. Tarsipes SPENSER^ Gray. 



" Seeming to prefer damp localities in the vicinity of Ti trees 

 (Melaleicca), among the branches of which they are said to build 

 small round nests, like Dormice." — G. C. S. 



31. Dromicia concinna Gould. 



" Said to be fairly plentiful near Parker's Range." — G. C. S. 



32. PSEUDOCHIRUS OCCIDENTALIS Thos. 



" Apparently local, frequenting well-watered districts. Plentiful 

 in some localities. 



" Native name, ' Wormp.' " — G. C. S. 



33. Trichosurus vulpecula Kerr. 



20 from Stockpool, Dwaladine, Woyaline, and Dale River. 



"Abundant and generally distributed throughout the South- 

 west, although very much thinned out in the more settled districts ; 

 not extending in any numbers far inland. The red patch on the 

 throat only appears in adult specimens, often becoming more 

 suffused over the rest of the body in aged individuals. The black 

 form seems to be local and more plentiful in the coastal districts. 

 The common method of trapping ' Possums ' is b}^ a snare set on a 

 slanting stick fixed against the base of a tree. They will always 

 come down a tree on the sloping side, however slight the slope 

 is; and the stick being in a more sloping position still, they 

 invariably run down it and get caught in the snare. 



"Native name, ' Coomul.'" — G. C. S. 



34. Thalacomys lagotis Reid. 



15 from Woyaline. 



Mr. Shortridge has drawn my attention to the fact that this 

 animal has a distinct horny spur at the tip of its tail, of a similar 

 nature to that in Onychogcde lunata. 



" With the exception of Bettongia lesueicri, this seems to be the 

 only true burrowing marsupial in the South-west. Bettongia 

 2Jenicillata and the Bandicoots dig little holes in the ground in 

 search of roots &c., but they do not live in burrows. It makes a 

 larger and deeper burrow than B. lesueuri, and, like a badger, it 

 is difficvilt to dig for, as it will burrow almost as fast as a man can 

 dig. Although more plentiful near the coast, it has a wide i-ange 

 inland, occurring sparingly as far as Laverton ; but for some 

 reason it seems to have become scarcer in the interior than 

 formerly, for while old burrows are plentiful, it seems to have 

 almost left parts of the country where it was once well known—
