ON THE NEW-GUINEA MAMMALS. 191 



80. Phalanger leucippus Thomas. 



Another new form of Phalanger from about the very 

 locahty of Carmelitae^ collected by Loria on the Upper 

 Vanapa-river, British New-Guinea. Size rather smaller 

 than in orientalise skull, although that of a fully adult 

 male, very like that of the female of orientalis, so far as 

 the interorbital region and its ridges are concerned; pre- 

 molars abnormally large ; the male grey as in females of 

 other species. Head and body of an adult male, the single 

 specimen whereupon the species has been based, 480 mm., 

 tail 340 mm.; skull, basal length 79 mm., greatest breadth 

 55 mm. (Thomas, Ann. Mus. Genova, 1898, p. 7). 



81. Pseudochirus Schlegelii Jentink. 



The single known specimen is an adult male , the 

 type, from the Arfak-Mountains, New-Guinea, procured 

 through Mr. Frank in 1879 (Notes Leyden Museum, 1884, 

 p. 110). Head and body 26 cm., tail 25 cm.; skull, 

 basal length 51 mm., greatest breadth 30mm. 



82. Pseudochirus Forbesi Thomas. 



Forbes collected two specimens, a male and female, at 

 Sogore, S. E. New-Guinea (1750 — 2000 feet). Agreeing 

 very closely with canescens and Schlegelii it yet differs 

 remarkably from all in the total suppression of its posterior 

 incisors and anterior premolars (Thomas, Catalogue, 

 1888, p. 184). Head and body 280 and 225 mm., tail 

 280 and 152 mm.; skull, basal length 47.7 mm., greatest 

 breadth 30 mm. Loria collected specimens from Haveri 

 and Moroka (near Mount Wori-Wori), Gerekanumu (on 

 the southern slope of the Astrolabe Range), and Upper 

 Vauapa district, all British New-Guinea. Dr. Loria's spe- 

 cimens show that the original example had accidentally 



r^otes from, the Leyden Museum, A^ol. XXVIII.
