Diagnosis. — Size as N. lullidcc (if not a little smaller : forearm 

 about 06 mm.), but ears much longer and fur of back uniform from 

 base to tip. Nah. Queensland (Cooktown). 



Perhapq the Australian representative of the iV. geminus type. 

 Size and general shape of skull as in i\'. lidlula; (Woodlark 1.), 

 but orbit noticeably larger (diameter 9'3-9*5 mm., against S'o in 

 N. lulhila>), body of mandible weaker, coronoid narrower, more 

 slanting backward, and only very slightly expanded at base ante- 

 riorly, and angular process less prominent ; size and characters of 

 teeth as in lulluke ; secondary cusp of upper canines obsolescent, 

 outer ridges of lower cheek-teeth sim])le. Externally at once 

 distinguished by the unusually large and more acutely pointed ears, 

 these being equal in length to (in lulhilfK and the other represen- 

 tatives of the geminus type much shorter than) tlie hind foot with 

 claws, and by the absence of dark (seal-brown) bases to the hairs of 

 the back. Males similar in colour to same sex of N. geininus and 

 scitulus, but with the flanks of a somewhat deeper tinge ; females 

 unknown. Membranes from first phalanx of second toe. 



The only other species of Nyctimene known from Australia is the 

 much smaller N. papuanus (forearm 51'5-59 mm.). 



Colour. — Type ( J ad., skinned from alcohol) : General colour of 

 back a dark wood-brown tinge of Isabella ; individual hairs uniform 

 from bases to tips (in all other species of the geminus group sharply 

 contrasting seal-brown at base) ; a well-marked narrow seal-browa 

 spinal stripe along the whole of the back. Head and nape of neck 

 similar to back. Underparts pale isabella tinged with tawny- 

 olive along middle line from throat to belly, dark russet (or dark 

 cinnamon) along flanks and in anal region. — A paratype (al., same 

 sex) is very similar in colour, though rather paler (more pure 

 isabella) on back. 



Measurements. On pp. 718, 720, 722. 



Specimens e.vaniined. The type and paratype (both in collection) 

 appear to be the only specimens on record.
