436 Mr. 0. Tlionias on Mammals from 



in his Catalogue, a monograph which has entirely revolu- 

 tionized our knowledge o£ the group. The fact also that the 

 genus is named after Dr. G. E. Dobson creates a suitable 

 juxtaposition of two names that must always be historical in 

 connection with the classification of the Chiroptera. 



4. Nyctimene vizcaccia, sp. n. 



Kuk Island. One specimen. Female. Collected 31st 

 July, 1913. B.M. no. 14. 4. 1. 31. Ti/pe. 



Allied to N. varitis, K. And., with which it shares the 

 varied Vizcacha- or Lagidium-Vike fur, strongly spotted con- 

 dition of wings, and coalescence of the inner wMth the main 

 cusp of 2^^} hut distinguished by the further coalescence of 

 the corresponding cusps in the lower jaw and by its greater 

 size. 



Size medium, just on the upper limit of Dr. Anders n's 

 " small " species. Fur long, hairs of back nearly 10 mm. in 

 length. General colour above irregularly varied drab-grey, 

 singularly liki^ thatof Laaidium, and in this way corresponding 

 \\\th that of N. vm-ius and differing from that of the more 

 uniformly coloured N. papuanus. Dorsal streak beginning 

 at withers, rather well marked considering the waviness of 

 the hair, but not nearly so much so as in N. jiapiumus. 

 Under surface drabby grey laterally, pale buflfy mesially, 

 paler than in varius. Ears, arms, and digits profusely 

 spotted with yellow, more so than in the allied species; wing- 

 membranes also much mottled with yellow. 



Skull much larger and heavier than that of N. varius, 

 slightly exceeding in size the largest skulls of N.papuanus. 



Teeth agreeing with tliose of iV. varius and minutus in the 

 fusion of the inner with the outer cus[) of ]/, but differing by 

 the further fusion of the coiresponding cusp oi' p^. 



Dimensions of the type : — 



Forearm 60 mm. 



Third finger, metacarpus 44, first phalanx 32 ; lower leg 

 and hind foot (c. u.) 37. 



Skull: greatest length 20*8; zygomatic breadth lI)-7; 

 interorbital breadth G'3; palatal length Jl'7 ; maxillary 

 tooth-row 10. 



Type as above. 



Tliis species curiously bears out Dr. Andersen's arrange- 

 ment of the genus by the correlation of its wavy fur with 

 the structure of p^, just as in his group " b^," consisting of 

 N. ininulus and varius. Then, being even more mottled and 

 spotted, it equally goes further in dentiti m, by its ;>;, also
