and the colour differem • - are also of dubious value, so I prefer 

 not to apply any subspecific name to this monkey. In view of 

 the genera] oological affinities of the Rhio-Lingga archipelago 

 it will probably prove to he allied rather to the Sumatran than 

 to the Peninsulai 1 ice and I have therefore used Raffles name 

 which was conferred on specimens obtained in the neigh- 

 bourhood of Bencoolen. 



Measurements in Parentheses are those of the type of 

 Pithecus bintangeusis as given by Elliot. 



Ckociduka maporensis, Robinson & Kloss, sp. nov. 

 Type. Sub-adult female (skin and skull) collected on the East 

 side of Pulau Mapor, Rhio-Lingga Archipelago, on 5th June, 

 1915, by H. C. Robinson. 



Diagnosis. In colour closely resembling C. aoris, * but 

 smaller, about the same size as C. negligens t but colour less 

 pure grey. Skull rather broader than in the allied forms. 



Skull:' Broader relatively than that of C. aoris and rather 

 more inflated in the anterior portion of the frontal region than 

 in that species. 



Measurements: Greatest length -(23"8)t ; basal length, 

 18.5 (21. 1); lachrymal breadth of rostrum, 5 - i (4.9); greatest 

 breadth above molars, 7*3 (7'g); cranial breadth above mastoid, 

 10 6 (10*5); maxillary tooth row, including iucisors, g - 3 (iO'O). 



Remarks. Though the material is very bad, the only 

 specimen obtained being much damaged by the trap and br- 

 ants, we have little doubt that the Mapor shrew is a fairly 

 distinct form. It is the first occurrence of the genus in the 

 archipelago.
