soine Australasian Mammals. 427 



Five skulls of tin's species are in the Museum collection 

 all of practically the same dimensions, while two from West 

 Australia are both of the larger size indicated bj the 

 Catalogue measurements. 



Th. sagitta is clearly the " common species or ' Urgarta/ 

 PeragaJe Ingotls^" of Prof. Baldwin vSpencer^s description * of 

 a new species of this genus from Central Australia, T/i. minor, 

 which he distinguishes, no doubt rightly,, by its still smaller 

 dimensions and its different habits. 



Mr. Hillier gives the local name for this animal, as used 

 by the Diari natives, as " Kapita.'^ 



Phascogah IlilUeri, sp. n. 



Near Ph. cristicauda^ but conspicuously paler in colour 

 throughout. 



Size about as in Ph. cristicauda. Fur soft and fine ; hairs 

 of back about 9 mm. in length. General colour above a 

 beautiful soft drab-colour, similar to but decidedly paler than 

 Eidgwaj^s "ecru-drab""; a few fine longer hairs black, 

 contrasting curiously with the general pale colour. Sides 

 more wdiiti^h drab, passing without sharp line of demarcation 

 into the pure white under surface, on which region, from 

 chin to anus, the hairs are pure white to their bases. Top of 

 head like back, but rather more fawn. Cheeks and lips pure 

 white. Ears thinly clothed with whitish hairs, an incon- 

 spicuous whitish patch behind their posterior bases. Upper 

 suiface of hands and feet snowy white ; structure of feet 

 apparently as in Ph. criuicauda. Tail slightly incrassated 

 basally ; crested above for its terminal two inches, the hairs 

 attaining a length of 16 mm. ; nothing tliat can be called a 

 crest below, though some of the hairs towards the end 

 are slightly longer than on the proximal part. In colour 

 the main part of the tail is rather more rufous than the 

 general body-colour, though nothing like the corresponding- 

 part in Ph. cristicauda ; under surface indistinctly darker, not 

 black ; crest glossy black. 



Skull unfortunately lost. 



Dimensions of the type (measured in the flesh) : — 



Head and body 150 mm. ; tail 100; hind foot 30; ear 27.
