76 MR. C. BODEN KLOSS ON 



I have a male Macaque from Trangbom, 30 miles east of 

 Saigon, to which they bear a general resemblance : but until I have 

 compared the specimens from both places with the type of Elliot's 

 race they had better remain undetermined subspecifically. 



All these do not differ in colour from M. i. atrieeps mihi 

 (Journ. Nat. Hist. Soc. Siam, III, 1919, p 347. Koh Kram Id., 

 Inner Gulf of Siam) as much as I thought from Elliot's description 

 of it that validus did. M. i. atrieeps, however, is easily separated 

 from the Cochin-China and Pulo Condore animals in having the 

 black area on the crown smaller and much more sharply margined, 

 while its skull can easily be distinguished by the unusually small 

 size of the orbits : it is further separated from the Pulo Condore 

 examples by the larger molars and more arched, horse-shoe shaped 

 palate, the breadth of which between the last molar.5 is much 

 reduced. 



This is the first time the Pulo Condore " monkey " has been 

 identified as a form of Macaque. 



I give, with the measurements of the present specimens, the 

 dimensions of two more examples of M. i. atrieeps, sent me by Mr. 

 W. J. F. Williamson, which confirm the description of the original 

 series.
