1906.] ON MAMMALS FROM WESTERN AUSTRALIA. 763- 



wliicli shows already a. membranous and somewhat pointed® fold 

 directed backwards, the future concha. Between the prominence 

 produced by the liver and the abdomen in general on the one 

 side and the snout on the other, appears the fore-leg bent 

 downwards. On the surface of the abdomen slight traces of 8 or 

 9 ribs may be observed. The hind-leg is not very clear, as parts 

 of the membranes have dried with it. The tail is rather long and 

 disappears in the membranes. Thi'ee chai'acteis may be pointed 

 out as especially ungulate: — 1, the small size of the head ; 2, the 

 length of the fore-leg, which distinguishes also shoep and deer 

 from pig embryos of the same stage ; 3, the length of the tail. 



I am obliged not only to Dr. I. David, but also to Prof. F. 

 Keibel, who kindly veiified my statements. 



2. List of further Collections of Mainnials from Western 

 Australia, including a series from Bernier Island, 

 obtained for Mr. W. E. Balston ; with Field-notes by 

 the Collector^ Mr. G. C. Shortridge. By Oldfield 

 Thomas, F.R.S. 



[Received August 18, 1906.] 



In the March number of the ' Proceedings ' * I gave a list of a 

 number of mammals obtained in )S.W. Australia by Mr. G. 0. 

 Shortridge, who had been commissioned for the purpose hj 

 Mr. W. E. Balston, by whom a complete series has been presented 

 to our National Museum. 



In making his first collection Mr. Shortridge had been 

 disappointed at the rarity oi* absence of many of the species 

 supposed to be common and characteristic of Western Australia. 

 Fortunately, however, in making the second collection he hit on 

 a region whei-e the fauna still pei-sists in its original state, and he 

 has therefore been able to send home a remarkably fine series 

 of a number of species hitherto only represented by faded old 

 specimens of the Gould & Gilbert era, or by the one or two 

 examples picked up as great rarities in regions where the native 

 animals have been more nearly killed out. 



The places now visited were four in number — Stockpool, 

 Dwaladine, and Woyaline, respectively some twenty to thirty 

 miles to the east of Burnley, Brookton, and Pinjelly, stations 

 south of York on the Perth-Albany railway-line, and Dale River, 

 a similar distance to the west of the line. These localities are all 

 in the upper part of the watershed of the River Avon, in the 

 county of the same name, about 117° E. and between 30" and 

 31° S." 



Finally, Mr. Shortridge paid a visit to Bernier Island, ofi:
