424 Mr. O. Thomas on 



Colour about as in D. paliata, the liead similarly dark 

 Listre-brown and tlie nape drab-brown ; under surface dull 

 isabella-brown. Back more entirely naked than usual, 

 absolutely hairless everywhere except just over the base of 

 the tail. 



Skull very similar in its proportions to that of D. j)aliata^ 

 but very much larger, the difference corresponding with that 

 found in Nyctymene aello as compared with i\^ major, while 

 Dobson's JJohsonia minor may similarly ratdc with the 

 smallest species, Nyctymene cephalotes, of the allied genus. 

 These differences may best be seen by the dimensions given 

 below. Teeth on the whole broader in proportion to their 

 length than in D. paliata^ but there is a good deal of 

 variation in this respect in the latter species. 



Measurements of the type (those marked with an asterisk 

 taken by the collector in the flesh) : — 



Forearm 145 mm.

 metacarpus 93, first phalanx 68, second phalanx 1(»3; fifth 

 finger 188, Lower leg and foot (c. u.) 107. 



Skull (measures in brackets tliose of an adult male skull 

 from Sumba) : greatest length ^i (51); basal length 55"5

 processes 28-5 (22-5) ; interorbital breadth 10-7 (9-8) ; inter- 

 temporal breadth 9 (S'S) ; palate length in middle line 29 (23) ; 

 front of canine to back of «/' 26*5 (21*5) ; length of canine 

 on hinder edge from cingulum 8*8 (5'2). Lower jaw, condyh 

 to front of

Dr. Matschie considers the members of this genus so 

 variable in size that he unites them all in one species, even 

 including the little D. minor, Dobs. But none of the dimen- 

 sions he gives at all approach those of this Papuan example, 

 and a comparison of the skulls shows such an immense 

 disproportion between it and those representing true I). paliata, 

 that it seems necessary to separate it. 



No other species has been described from this part of the 

 Papuan region.
