125 LLOYDS NATURAL HISTORY. 



Very nearly related to this species, if indeed it be really dis- 

 tinct, is the GOLDEN LANGUR, or Lootoong of the Malays, 

 S. AURATUS, Geoffr. (Ann. Mus., xix., p. 93, 181 2), which is 

 synonymous with the S. chrysomelas of Wagner, for the two 

 agree in every respect except that the latter is lighter coloured, 

 and has black hairs intermixed among the yellowish hairs on 

 its head, tail, and limbs. 



Professor Schlegel has (Mus. Pays-Bas, vii., p. 47) separated 

 a specimen from Singapore, and closely related to S. femoralis^ 

 as a distinct species, under the name of S. neglectus. It is 

 easily distinguished, as he points out, by the general hue of its 

 fur being black turning insensibly into greyish-brown, speckled 

 here and there with white ; in the middle line of the chest, on 

 the lower belly, and on the inner side of the fore-arm, and thighs 

 alone, is there any white ; this and the uniformly dark tail 

 distinguish S. negkcius from S. fanonilis and S. chrysomelas.

Characters. — Differs from S. riibicundus in its rich deep 

 maroon-red colour, the radiating hair on the forehead, and 

 its compressed, semi-erect, crest. As Dr. Anderson points 

 out, it is the only species with radiating hair on the forehead. 



Habits. — Mr. Hose observes : "This handsome red Monkey 

 is called by the Dyaks of Sarawak, ' Jellu merah,' and by the
