 1904, by A. S. Meek. 



Tliis bat is presumably the representative in the low-lying 

 coast-country of the N. microtis of tiie mountains behind. I 

 have, however, seen neither spirit-specimen nor baculum of 

 it, so that it may possibly prove to be more distinct from 

 JSf. microtis than I can now determine. 



7. Nyctophilus dcedaliis, sp. n. 



Size fairly large. Ears about as in N. bifax, smaller than 

 in gouldi. Colour, of a skin from Melville Island, rich 

 brown, between Prout^s brown and mummy-brown ; under- 

 side lighter, near " Saccardo's umber.^' Nose-leaf low, little 

 developed, as No. 1 above. Skull much as in N. bifax, the 

 bull» markedly smaller than in N. gouldi. Baculum short, 

 tapering, flattened terminally, not bifurcate. 



Dimensions of the type (in spirit) : — 



Forearm 41 mm. 



Head and body 52 ; tail 41 ; ear 22 x 15*5 ; third finger, 

 metacarpal 37'5, first phalanx 15 ; lower leg and hind foot 

 (c. u.) 25. Baculum 3*7. 



Skull: greatest length 17*3; condylo-basal length 16; 

 zygomatic breadth 11*6 ; palato-sinual length 6"6; maxillary 

 tooth-row 6*5 ; bullse 3*6. 



Hob. Northern Territory. Type from the Daly River ; 

 other specimens from Port Essington and Melville Island. 



Type. Adult male. B.M. no. 97. 4. 12. 8. Collected 

 July 1894 by Dr. Dahl. Received in exchange from the 

 Christiania Museum. 



This species differs from N. gouldi by its smaller bullae 

 and less developed nose-leaf, and from N. bifax by its simple 

 baculum.
