Agree with topotypes from Trang except that the white area 

 appear to be somewhat reduced, that on the inner side of the thigh 

 not extending as far as the* heel. 



Very common in parties of five or six in primary and secondary

 land. 



In a recent paper {Smithsonian Misc. Coll., vol. 61, No. 21, p. 28, 

 1913), G. S. Miller has restricted the name P. femoralis, at one time 

 applied to monkeys of this type, ranging from Tenasserim, through 

 the Malay Peninsula to Sumatra and Borneo, to the form inhabiting 

 Sino-apoi-e Island, though some ambiguity attaches to the real origin 

 of Martin's type. 



In view of this we have preferred to use the name Presbytis 

 neglecta (Schlegel) (Mus. Pays. Bas., vii, p. 47, 1876) for the animal 

 from Sino-apore and to regard this as the primary name available for 

 the Peninsular animals. 



In the same paper Miller has also given a diagnosis of a new i-ace 

 from Johore, stating that it is similar to that from Singapore Island 

 but is larger than that form, having the grejitesfc length of skull, 

 about 95 mm. His description is founded on five specimens, four 

 from Johore and one from Southern Pahang. A male specimen 

 from Singapore in the Federated Malay States Museum has the 

 o-reatest skull length 89.3 mm., two specimens in the British Museum 

 from Puiai, South Johore measure 89.9 and 86.3 respectively, and 

 a male and a female from Segamat, N'orth Johore, are 88.5 and 86.5 

 respectively, while the length given by Miller for his specimen from 

 Singapore is 88.3. 



Of the northern race P. n. heatii, five males range fi'om 92 to 

 96.7 and four females from 92.4 to 97.0 mm. It is evident therefore 

 that the series in our possession does not confirm Miller's conclusions 

 as to the separability of animals from Johoi'e and Singapore, though 

 there is no doubt that the northern race is distinct from these both 

 in size and colour.

The adult agrees closely with the type from Trang. 



This white lotong is common on Kao Nawng where it is almost 

 always found associating with small parties of the preceding form, of 

 which it is very probably an aberration. It may be remarked that 

 all three specimens known to date present abnormalities in the 

 structure and character of the hair, the patches of pigment being 

 irregularily distributed through them, while the unpigmented
