Diagnosis. — Au eastern representative of N.cyclotis (Arfak Mts.), 

 distinguished bj' its much heavier dentition and the much darker 

 colour of its fur. Hah. So far known from Mt. Goliath, S.E. Piutch 

 New Guinea, and Aroa lliver, E. New Guinea. 



Dentition. — Molariform teeth, as in ci/clotis, subcircular in outline, 

 ■with m' and m, conspicuously smaller than, respectively, p* and p^, 

 but all cheek-teeth much heavier, particularly broader, than in the 

 related species : — p^ (length and breadth) of type (between paren- 

 theses corresponding measurements of the tj"pe of ci/clotis, for 

 comparison) 2-2 x 2-1 (2-0 X 1-7), p' 2-0 x 1-8 (1-8 x 1-6), m' 

 1-8 x 1-6 (1-6 X 1-3), P3 2-5 x 2-0 (2-3 x 1-7), p, 2-3 x 2-0 (21 x 1-7), 

 m, 2-0 X 1-7 (1-9 X 1-5), m, 1-3 x 1-2 (1-2 x 1-1). 



Ears. — As in ci/clotis, unusually broad, semieircularly rounded 

 off above, and narrowly edged all round with yellow, this yellow 

 edge interrupted here and there by the dark central colour of the 

 ear conch extending to the margins of tlie ear. 



Colour of fur (tj'pe). — Peculiarly mottled above, as in N. cyclotis, 

 but much darker. Individual hairs of back seal-brown at extreme 

 base (for about 5 mm.), then very pale wood-brown (for 5-6 mm.), 

 with short (2 mm.) dark brown tips, the mottled appearance of tho 

 colour of the head and back due to the dark brown tips of the hairs 

 being too short to cover completely the paler middle portion of the 

 hairs ; a narrow and somewhat ill-defined dark brown spinal stripe 

 along posterior half of back ; breast and belly pale greyish drab in 

 centre, flanks fawn. 



Measurements (of type). — Porearm 58, second digit (metacarpal, 

 first phalanx, second-third phalanx c. u.) 27-|-5'5-f 9-5, third 

 37-5-1- 32-1- 40-5, fourth 35 -|- 24 -f 26-5, fifth 36-5-|-21-5-f23, tibia 

 205, foot (c. u.) 16 mm. 



Skull — across crowns of m'-m' (externally) 8'S, across canines 

 (externally) 6-5, between p''-p'' 5-7, between bases of canines 2, 

 mandible 22-8, c-m' (crowns) 9*8, c-m^ (crowns) 11-2 mm.
