1906.] MAMMALS FROM NORTHERN AUSTRALIA. 541 



Dimensions of the type, measured in spirit : — 



Head and body 76 mm. ; tail 74; hind foot 13'5 ; ear 16. 



Skull — greatest length 24' 7 ; basal length 22 ; zygomatic 

 breadth 14-6 ; nasals 9 ; interorbital breadth 5-3 ; height of 

 crown above basion 5*6 ; palate length 13 ; breadth at outer corners 

 of penultimate molar 8*8 ; antero-posterior length of bullae 5"8 

 (6'8 in Ph. macdonnellensis) ; combined length of three anterior 

 molariform teeth 5*2. 



Hah. and Type as above. 



This species shows affinity to the Central- Australian Ph. mac- 

 donnellensis by its absent lower secator and its rufous ear-patches, 

 but is distinguished by its smaller size, shorter fur, greyer colour, 

 smaller buUse, and by the increased development of its upper 

 secator, a development quite anomalous in the case of a species 

 without a lower one. In Ph. macdonnellensis Prof. W. B. Spencer 

 records that in every one of 13 specimens examined this tooth is 

 either absent or very minute, so that the presence of a well- 

 developed double-rooted upper secator clearly indicates specific 

 distinction.

A remarkably small species, with minute teeth and flattened 

 skull. 



Size veiy small, slightly smaller even than in Ph. minutissima. 

 Fur soft, close, and fine; hairs of back about 4 mm. in length. 

 General colour above not unlike that of the paler wild-living 

 forms of lius muscuhos, something between Ridgway's " wood- 

 bi-own " and " broccoli-brown," the hairs slaty grey with pale 

 tips. A younger specimen is clearer grey, without the drabby 

 tone. Under surface paler, with a yellowish tinge, not sharply 

 defined, the hairs slaty at base except on the chin. Crown like 

 back. Cheeks and chin whitish. A whitish-buflfy line just over 

 each eye. Ears of medium length, their fine hairs buffy whitish. 

 Upper surface of hands and feet whitish. Tail of medium length, 

 vmiformly short-haired, about as in 31iis muscidus, not pencilled, 

 pale brownish white, scarcely lighter below. 



Skull remarkable for its extraordinary flattening, a flattening 

 only equalled in 4 other mammals *, three being bats, the height in 

 profile view from the base of the skull in front of the bullae to the 

 crown only 3-3 mm., as compared with 4-7 mm. in a skull, other- 

 wise little larger, of Ph. minutissima. Zygomata evenly convex 

 outwards. Nasals well expanded in their posterior half. Inter- 

 orbital region flat, its edges without ridges. Occipital crests 

 almost obsolete. Anterior palatine foramina reaching to the level 



* Graphiurus platynps, Tijlonycteris pachi/pus, MimctiUvs Tiioloneyi, and Fla- 

 tjjmops macmilla ni.
