534 Mr. 0. Thomas on 



forearms only attaining about 31 mm. The present form 

 would appear to be a highland subspecies, characterized by 

 it.s markedly greater size. 



Meyer's Vesperugo papuanus orientalis of Astrolabe Bay is 

 apparently quite the usual New Guinea Pipistrel. 



Emballonura meeki locusta, subs p. n. 



External characters quite as in true meeki, and size similar, 

 though the single specimen seems rather less robust than the 

 example of meeki, and the limb-bones more slender. The 

 characteristic broadly lobed lips, the shape of the tragus, and 

 the long, slender, grasshopper-like hind limbs all as in the 

 typical form. 



Skull smaller and lighter than in meeki. Inflation of 

 muzzle much less, the inflated upper portion of the maxillaries 

 of the two sides not extending inwards towards or to the 

 middle line, as is the case in meeki, but keeping widely sepa- 

 rated throughout, so that the nasals between them are parallel- 

 sided and not contracted anteriorly. Behind the nasals, the 

 forehead is more deeply concave mesially, the general con- 

 cavity between the inflations extending back into the inter- 

 orbital space ; the rounded supraorbital edges are not specially 

 inflated in meeki, but are in locusta. Basial fossae as in meeki, 

 not as in subsp. clavium. 



Dimensions of the type : — 



Forearm 38 mm. 



Head and body 40 mm. ; tail 13 ; ear 12 ; lower leg and 

 foot (c. u.) 203 ; calcar 15. 



Skull: greatest length 12; condylo-basal length 11*1; 

 nasals, breadth between inflations anteriorly 0*9 ; interorbital 

 breadth 3; mastoid breadth 6'S; front of canine to back of 

 «i 3 4'4. 



Hah. Schouten Island, N.W. New Guinea. 



Type. Adult male. B.M. no. 20. 10. 23. 2. Collected by 

 Messrs. Pratt Brothers. One specimen only. 



Readily distinguishable from true meeki and from meeki 

 clavium by the reduced maxillary inflations, which do not 

 trespass on the nasals between them. 



Pogonomys sylvestris, sp. n. 



A medium-sized species with slaty bases to the belly-hairs. 



Fur long, soft, and fine. General colour above dark 

 rufescent — near " auburn" ; sides more rufous ; under surface 

 greyish ; the hairs broadly slaty basally, with creamy whitish 

 tips. Hands and feet pale bufiy. Tail pale brown, its fine 

 sparse hairs whitish.
