PITHECUS FUSCUS LASIAE, new Bubspecies. 



1903. Macacus fuscus Miller, Proc. U. S. Nat. Mus., vol. 26, p. 476, February 3, 

 1903. Type-locality: Simalur. 



Type-specimen. — No. 114248, U.S.N.M., skin and skull of adult 

 male, collected on Pulo Lasia, January 5, 1902, by Dr. W. L. Abbott; 

 original number, 1398, 



GeograpMc distribution. — Pulo Lasia. 



Diagnostic characters. — Essentially like the typical Pitliecus fuscus, 

 except that black of back of neck and upper part of back is slightly 

 more conspicuous ; tail decidedly longer than head and body and more 

 than 500 mm. in length. 



SlniU and teeth. — These show no characters to distinguish the Lasia 

 race from that inhabiting the larger island. 



Measurements. —TyY^e: Head and body, 470 mm.; tail, 555; hind- 

 foot, 135; condylobasal length, 96 ; width of braincase, 58 ; postorbital 

 constriction, 39; maxillary tootlu-ow, 40 ; weight, 14 pounds (6. 3 kilos). 



Specimens examined. — The type and an immature male. 



Remarks. — Pithecus fuscus lasiae is a slightly modified form of P. 

 fuscus. The material on which it is based is not entirely satisfactory 

 as to numbei-s, but the long tails of the two specimens are not equalled 

 by any of the eleven from Pulo Simalur. This peculiarity of the Lasia 

 specimens was pointed out by Miller in 1903.
