 their bases, their terminal halves creamy white.

Ti/pe. B.M. no. 5. 11. 28. 2. Collected 20th December, 

 1904, by A. S. Meek. 



This bat is presumably the representative in the low-lying 

 coast-country of the N. microtis of the mountains behind. 1 

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

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

 JV. microtis than 1 can now determine. 



7. Nyctophilus dcedalus, sp. n. 



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

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

 brown, between Prout's brown and muu)my-brown ; under- 

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

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

 bullae markedly smaller than in iV. 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 j lower leg and hind foot 

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



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

 zygomatic breadth ir6 ; palato-sinualiength 6"6; maxillary 

 tooth-row 6'5 ; bullae 3*6. 



Tlab. Northern Territory. Type from the Daly River ; 

 other specimens from Port Essington and Melville Island. 



Type. Adult male. B.M. no. 97. 4. 12. i<. 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.
