46 SIMIID^. 



The British Museum contains the type of 31. melanotus and the specimen of 

 If. hriimieus which was figured in the Zoological Society's " Proceedings," whilst 

 the type from which the external characters of M. brwmeiis and the details of its 

 anatomy were drawn up is deposited in the Indian Museum, Calcutta. "With the 

 skin and skull of the type of M. melanotus I have compared the first-named specimen 

 of M. brunneus and its skull, also the skull of the type of the species in Calcutta. 

 I cannot detect a single character hy which to separate them. The question now 

 suggests itself, Is this monkey really to he regarded as a native of Southern India ? 

 I think not, and that the prohahle history of 31. melanotus is that it had been 

 taken to Madras from Burma in one of the ships that traded between that 

 town and Eangoon, — two ports which have had for a very long period regular 

 and frequent communication with each other. And what strengthens this sup- 

 position is the circumstance that this form of monkey is unknown in Southern 

 India. It appears to be a case similar to that of the M. leoninus, Blyth, a female 

 of which was imported into the Andaman Islands from Burma, and was described 

 as 31. andamanensis. 



The type of M. melanotus and the specimen of 31. brunneus in the British Museum 

 are both examples of the male sex and of nearly equal size and age, with similarly 

 formed short tails, and in these respects agree with the type of 31. brunneus, which 

 was only slightly younger. On the upper surface of the head and along the back 

 the fm' is dark brown, approaching to blackish ; the sides and limbs are dark brown, 

 being slightly paler in 31. brunneus. In 31. melanotus there is a distinct tendency 

 to annulation on the sides of the neck and body, on the shoulders, and on the 

 limbs, the annuli being pale golden-yellow and brown, and rather numerous on 

 each hair, the terminal points being dark brown or blackish. These annuli are but 

 feebly developed, and require the aid of reflected light to make them clearly visible. 

 The type which I described was a younger animal, and did not show any signs of 

 annulation ; but the other example in the British Museum, and which had shown 

 no annulation, so far as I am aware, before it left Calcutta, had evidently developed 

 it afterwards during its life in the London Zoological Gardens. 



A large, red-faced monkey, with a stumpy tail like the previous specimens, was 

 purchased by the Zoological Society from a dealer in Liverpool, who could give no 

 information regarding its habitat. After living for some years in the Society's 

 Gardens it died, and was deposited in the British Museum, where it is now stuffed 

 and the skeleton and skull are preserved. In its general form it is exactly like 

 31. brunneus, but only much larger, and it differs from it and 31. melanotus in the 

 general annulation of its hair all over the body even to the under parts, which 

 however, are not so distinctly annulated as the upper surface. The characteristic 

 feature of the fur is the regularity and uniformity of the annulation, and the 

 great number of annuli which occur on each individual hair ; I have counted 

 as many as twelve or fourteen. These rings are of the same type as those I have 

 indicated as existing in a subordinate degree in M. melanotus and M. brxmneus. It is
