628 On Two neio Species of Sloic-Loris. 



Fur very long, soft and fine, far softer and finer tlian in 

 N. ceucang. General colour greyish waslied with dark bufFy. 

 Dorsal stripe blackish, continued forwards on to the crown, 

 where it meets four blackish lines which rise from in front 

 of the ears, and from the black orbital rings on each side, tlie 

 spaces between these lines contrasted whitish. Temporal 

 area and sides of neck prominently whitish, in marked con- 

 trast to the black mesial band. Hands and feet dull buffy 

 whitish. 



Skull rather small. Upper incisors two. 



Dimensions of tlie type (measured in the flesh) :— 



Head and body 290 mm.; hind foot 72; ear 23. 



Skull : greatest length 58 ; zygomatic breadth 38 ; front 

 of canine to back of m^ 21. 



Hah. W. Java. Type from Batavia. 



Type. Female with basilar suture not quite closed. B.M. 

 no. 9.1.5.34. Original number 1373. Collected 21st 

 February, 1908, by G. C. Shortridge. Presented by W. E. 

 Balston, Esq. One specimen from the type-locality, and 

 another, very similar, said to be frotn " Sumatra," coll. 

 RafHes, but this cannot be implicity trusted. 



This is, no doubt, the animal considered as javaniciis by 

 Stone and Ilelin and by Lyon in their respective papers on 

 the genus, and also the " variety C " of Blyth. But it would 

 seem not to be the xqoX javanicus of Geoflfro}^, whose descrip- 

 tion is evidently basf^d on one of the ordinary Malayan forms 

 without contrasted head-markings, which it is impossible to 

 believe that author would have omitted to mention. More- 

 over, there is in the Museum one of Horsfield's Java specimens 

 which does agree with Geoffroy's description, and this I con- 

 sider to be the i:ed\ javanicus. This Horsfield specimen is a 

 uniform reddish brown, with inconspicuous face-markings 

 and a brown dorsal stripe — in fact, very like specimens of 

 mcdaianus, — and thus agrees precisely with the description 

 oi' J avatiicns. Whether it really came from Java I cannot be 

 certain, but the island is quite large enough to contain tw^o 

 different forms of the genus. 



Furthermore, I believe this Hoisfield specimen oi javanicus 

 represents the true original coucavc/, Bodd., which, as shown 

 elsewhere (J. Bombay Soc. Nat. Hist.), is certainly not the 

 Bengal and Assam form, as commonly asserted, but one of 

 the Malayan species. N. javanicus should therefore be con- 

 sidered as a synonym of N. coiicang.
