TCINEIA lUDKXS. 59 



hrowu, tinged with rus.sot o!i rump. Entire underside, from throat 

 to interfemoral, inchiding tlanks, drab with a slight tinge of 

 brownish, rather darker on throat and foreneck than on breast and 

 belly. Nape and sides of neck golden bufty. A tuft of rigid 

 unctuous hairs on each side of neck, deep ochraceous at base, golden 

 buft'y at tip ; colour of tufts, in arranged fur, not conspicuously 

 differing from that of surrounding hair. Occiput, crown, sides of 

 head, and face darker brown than back. 



Sexual differentiation. — Females of this species are unknown. 

 They probably differ in having the neck tufts undeveloped or less 

 developed than males. 



Measurements. On p. GO. 



Specimens examined. Three males (two skulls), in the collections 

 of the Leyden and British Museums, including the tyjie of tlie 

 species and of B. menadensis. So far, these appear to bo the only 

 specimens known (December, 1908). 



Range. North Celebes : Menado, Eone, Gorontalo. (" Eotie," 

 the type locality of the species, is not, as naturally presumed by 

 Thomas and all later writers, the well-known Bone or Boni in 

 S. Celebes, but a mountain range and river in N. Celebes, very near 

 Gorontalo ; sec Bosenberg, Malay. Arch. p. 257, 1878, and P. & F. 

 Sarasin, Beisen in Celebes, i. map iii, 1905.) 



Tijpe in the Leyden Museum. 



Boneia hidens, Jentink ; 1879. — Type locality. Bone, N. Celebes 

 ( Bosenberg) ; type, an adult male, preserved in alcohol, skull in situ. 

 The second Leyden specimen, also a male, is mounted, and ticketed 

 Gorontalo {Rosenberg) ; skull extracted, very incomplete. 



Boneia menadensis, Thomas ; 1896. — Type locality, Menado, 

 N. Celebes ; type in collection. In this specimen the golden buffy 

 colour is restricted to the nape and sides of the neck, whereas in 

 the type of B. bidens it extends to the occiput ; in all other 

 characters the two specimens are identical. In view of the fact 

 (which was not known to Thomas) that B. menadensis is very 

 nearly a topotype of B. bidnis, there can bo no doubt that the 

 difFerence referred to is only individual.
