2. Pithecus vetulus nestor, Benn. 



Essential characters as in v. vetulus. General colour of 

 body dark brown. Crown of head paler than rest^ of back, 

 but contrasting less noticeably with the other dorsal parts 

 than in the typical form. Rump-patch normal, silvery grey, 

 but usually less conspicuous than in the other subspecies. 

 Frosting of buttocks and thighs inconspicuous or entirely 

 absent. Hands and feet dusky above. Tail dark grey at 

 base, paling to w^hite or cream-colour distally. 



Skull apparently intermediate between those of v. vetulus 

 and V. phillipsi. 



For cranial measurements^ see table at p. 514. 



Hab. S.W. Ceylon. 



Material examined. — Six^ viz., four specimens, including 

 the type (B.M, no. 55.12.24.12, ex Zool. Soc), without 

 any exact locality; and two (B.M. nos. 72.9.5.2 and 3, 

 presented by the Colombo Museum) from "Ray gam Corola.'' 



Remarks. — Bennett^s type is a mere baby with full milk- 

 dentition. But the other specimens include fully adult and 

 even old individuals; and the material seems sufficient to 

 show that P. V. nestor is a well-marked subspecies, dis- 

 tinguished from the others by its peculiar coloration. 

 Unfortunately, none of the specimens is accompanied by 

 collector's measurements, or by exact information as to 

 locality. " Raygam Corola '^ is a district immediately to the 

 north of " Pasdon Corola " and the Kalutara district ; and a 

 great part of it lies within the " wet area '"' ^. Possibly 

 the present form will be found to represent true vetulus in 

 the northern part of the '^ wet area." 



As to its coloration, dark brown though it be, it can 

 scarcely be regarded as an intermediate between the black 

 V. vetulus and the cold-grey v. phillipsi ; for while in each 

 of the latter forms the contrasts offered to the rest of the 

 dorsum by the crown and rump-patches are as strong as 

 possible, in v. nestor these contrasts are softened down, this 

 subspecies thus showing a well-marked tendency-to produce 

 a general uniformity of colour. 



3. Pithecus vetulus phillipsi, subsp. n. 



Essential characters as in v. vetulus ; distinguished by its 

 much paler general colour and more conspicuous crown- 

 patch. 



General colour of upper parts, including the outer surfaces
