Dr. Templeton's memoir on some varieties of the Monkeys of 

 Ceylon was then read : — 



"The Cercopitliecus pileatus ('Menageries,' M. sinicus, F. Cuv.) 

 is the common small monkey of every part of the western and south- 

 ern maritime provinces of Ceylon. It is readily distinguished from 

 the Toque by the light tan hue of the face and the black margin of 

 the lower lip. The male is more robust and not so i)layful as the 

 female ; both arc easily tamed, and retain their gentleness and fami- 

 liarity in old age. The figure in the ' Histoire des Mammiferes' 

 represents the animal much too stout, the tail rather short, the di- 

 stinction of colour of the back and abdomen marked by a too well- 

 defined line, and the hairs on the crown of the head not sufficiently 

 copious, long or divergent. In other respects the figure is good. In 

 that excellent little work the ' Menageries,' page 308, are these words : 

 ' with the long hair of the head standing erect, like an upright crest.' 

 This, applied to our animal, I have difficulty in compreliending ; the 

 hair on the head of the adult males and females being flattened down, 

 strikingly divergent from a small central part, and in some instances 

 slightly separated down the middle ; but anything like an upright 

 crest I have never yet seen. There are some slight distinctions of 

 sex and age which it may be proper to note, remarking at the same 

 time that the peculiarities, though obvious enough in the majority, 

 are by no means constant, but shade into each other, especially in 

 the domesticated animals. The adult male, as I have above remarked, 

 has the hair of the crown flattened down, equally divergent in all 

 directions, of the same colour and appearance as that of the back ; 

 that is, rather long, mouse-coloured close to the skin, yellowish 

 brown, or in strong sunlight golden with a shade of chestnut at the 

 tips. The face is light tan-coloured, with scattered black hairs : 

 along the eyebrows a few stiff black hairs projecting straightfor- 

 wards, and above these, and beneath the crowning tuft, a dark band 

 of hair ; the space about the ears whitish, ears fuliginous ; lower lip 

 with a broad black margin; conjunctiva black. Iris reddish brown, 

 pupil black. Anterior surface of the trunk and inner side of the 

 limbs pale. The hands are strong, fuliginous ; the dorsum thinly 

 covered with hairs, like those of the back. Tail thickish at the root, 

 mouse-coloured, not diminishing to a point ; apex light brown or 

 grey ; callosities tan- coloured, with the hair for about an inch sur- 

 rounding them fuliginous ; penis trilobed. The female has the legs 

 and arms of a redder tint, the inside of the upper arms and broad
