18 REPORT ON ZOOLOGY, MDCCCXLIII. 



character was given by Is. Geoffrey, has now been fully 

 described by him. (Archiv. du Mus. ii, p. 549.) 



The only species belonging to it is Simin Titlfipoin. A second, which he had 

 constituted under the name of M. capillatus, he has now himself withdrawn, 

 since it was founded only on a badly prepared skin. 



He has also (1. c.) given more detailed descriptions of Cercopithecits Iflhiatits, 

 leucampyx, monoidcs, Luhmdii, -pygerytlinis, and rufo-vindis. The last of these 

 (tab. iv), together with C. monoidcs (tab. iii), are also figured. He is still 

 inclined to retain the distinction between C. pyrrJionotus and ruler, simply 

 for the reason that in the former the nose is white, and in the latter black. 



The same naturalist again endeavours to vindicate the 

 specific independence of his Macacus aureus. (Archiv. ii, 

 p. 566.) 



He does not regard the M. aureus, in the voyage of the Bonite, to be tbe 

 true one, neither does he allow it to be identical with M. carlionurius. He 

 is also inclined to look upon an albino (tab. v), from the Philippines, as belong- 

 ing to a distinct species, which he provisionally terms M. plnlippmensis ; 

 another specimen from the same place will agree accurately, neither with 

 M. cynomolgus nor aureus. I observe that the coloured varieties brought 

 by Cumiug from the Philippines arc again different from those above men- 

 tioned, and this great variety in the colour favours the opinion broached first 

 by Schlegel, then by me, and soon afterwards by S. Mullcr, that all 

 these colours appertain to the great group of varieties presented by Inuus 

 cynomolyus. 



How far Macacus arctoides and maurus are identical or not, Is. Geoffrey 

 has not as yet been able to determine with certainty. The latter is probably 

 of the same species as the one I have described in Schreb. Suppl. i, p. 1-1S. 



Is. Geoffroy has now raised his subgenus Cynopitliecus 

 into an independent genus. (Archiv. du Mus. ii, p. 574.) 



" Body short, with tolerably long limbs, hands elongated, external thumbs 

 of moderate length, no tail. Skull moderately wide, superciliary ridges 

 much developed ; snout very long, broad and sloped, its sides at a right 

 angle with the upper surface. Eyes of medium size. Nasal fossoe very much 

 dilated, nose fiat, nostrils not tubular, and not apical. Callosities expanded." 

 Incisors inclined, the middle in the upper jaw very broad, the last inferior 

 molar with five tubercles. I have to remark, that the statement, " point dc 

 queue," must be corrected, -to this extent, that ilic tail is only a very short 

 stump. As the only species, Is. Geoffroy adduces Cynoceplialus niger, Desm., 

 which I have placed at the end of the short tailed Nacaci ; I do not consider 

 a distinct genus for it necessary.
