cephalopterus, silenus purpuratus, porphyrops, and latiharha 

 (all based primarily upon Pennant^s Parple-faced Monkey) ; 

 and latiharhatus and leucoprymnus (based upon more recently 

 collected material) refer to the form A. This is, tberefore, 

 the typical subspecies P. v. vetulus ; and of it the British 

 Museum possessed but two examples before the arrival of 

 the fine series collected at Anasigalla by Mr. Phillips. 

 These older specimens are : — one presented by the Colombo 

 Museum from the district of Pasdon Corola (79. 9. 5. 1), and 

 one collected by the Bombay Natural History Society^s 

 Mammal Survey at Kottawa in the Southern Province 

 (15.3.1.7). 



On the other hand, Bennett^s nestor (of which the type 

 is novv before me, B.M. no. 55.12.24.12) is based upon 

 form B ; and of it SchlegePs kelaarti would appear to be a 

 synonym. 



With regard to Presbytes thersites,^\Y\oi and Blyth, based 

 upon a living specimen obtained by Dr. Templeton at 

 Nuera-kelavva to the west of Trincomali, there is some 

 doubt, which can only be resolved by a re-examination of 

 the type in the Calcutta Museum. By Blyth "^^ Anderson t, 

 and more recently by D. G. Elliot J, thersites has been 

 treated as a synonym of P. priamus -, while Blanford §, 

 finding nothing in the description to distinguish the type 

 from ^' cephalopterusy" could not ^^ help suggesting that the 

 so-called Presbytes thersites was really a variety of Semno- 

 pithecus cephalopterus , perhaps approaching the variety 

 called S. kelaarti by Schlegel.^'' Blytli || (who saw the type 

 in life, as v.ell as after its death and preparation) describes 

 thersites as having no crest of hair upon the head ; and its 

 "whiskers and beard more developed than in the other 

 entelloid Indian species, and very conspicuously white, 

 contrasting much with the crown and body, which are 

 darker than in P. priamus J' In these respects^ no doubt^ 

 thersites^ as described, resembles vetulus ) but Blyth states 

 that the crown is darker and not lighter than other portions 

 of the dorsal surface, and he makes no mention of the 

 rump-patch so characteristic of all the known forms of 

 vetulus. There is no other evidence of the occurrence 

 of vetulus in N.E. Ceylon, while P. priamus is there a 

 common species. It is quite possible that thersites is really
