History in literature. — Original description based on four speci- 

 mens collected by Mr. Masters at Katow, British Xew Guinea, 

 ■where this species was found in large numbers clustering on the 

 leaves of a Xipa palm (^Xipa fruticans) overhanging the wat«r ; 

 their discovery was due to the fetid odour which pervaded the place 

 (Ramsay, ?. s. c). By Dobson (1878, I. s. c.) Ft. epiilarius was 

 believed' identical with Pt. macrotis. The species was justly kept 

 separate from Pt. macrotis by Matschie (1899, I. s. c.) on account of 

 its smaller size. 



liemarks. — The chief characters of this species are the peculiarly 

 short cheek-teeth with nearly obsolete posterior basal ledges, the 

 large eye?, long and pointed ears, and light buffy mantle contrasting 

 with dark brownish or blackish back and underparts. In shape
