A Nycticebus, which agrees with M. A. M. Edwards' figure of the Siam form, 

 occurs in the Kakhyen Hills to the east of Bhamo. I procured an adult male, 

 and it agrees with N. cinereus, A. M. Edw., viz., in colouring, in the form of the 

 skull, and in the numher of incisors in the upper jaw. A. M. Edwards remarks 

 that " les yeux sont entoures d^un cercle de poils generalement Monds,'' but in his 

 figure the eyes are surrounded with brown, whilst a white band occurs between 

 the eye and the ear, external to the brown area surrounding the eyes, and joining 

 above and below with the central white area of the face, and the Bham6 specimen 

 in these respects resembles the figure. 



It is the form which is found in the Assam region, from whence I have fre- 

 quently obtained it ahve, of both sexes, young and adult. The specimens received 

 by me have generally come from the Garo Hills, but Blyth^ records it from 

 Tippera and Aj*racan, but with regard to the latter locaUty, it may be men- 

 tioned that he recognised only one species, N. tardigradus,^ to which, however, 

 he referred three varieties distinguished by the colour of the fur and the number 

 of the incisors. His variety A was this species ; his variety B the darker-coloured 

 and more rufous Malayan form without weU-defijied markings on the head and 

 with four upper incisors, which he received from Malacca ; and C, the Java 

 variety, with only two upper incisors and with four weU-defined broad head-bands of 

 dark brown. 



The varieties A and B are not unfrequently offered for sale in Calcutta, but the 

 latter is rare in Eastern Bengal, the explanation of its occasional presence in 

 the Calcutta mart being that it is brought thither in the course of trade between 

 Calcutta and the ports of Arracan, Burma, the Malayan peninsula, and Singapore. 

 The light-coloured form A, on the other hand, is from Assam, and consequently is
