Cercoleptes caudivolvnlus (p. 245), add : — 



The Kinkajou was formerly considered a Lemur ; and the manner 

 in which it uses its feet as hands might well mislead a casual ob- 

 server. I saw one the other evening in the Zoological Gardens 

 resting on its rump with the tail coming out in front between its 

 hind legs. It was holding in its fore feet a sUce of bread; and 

 every now and then it would take off a piece with one or the other 

 of its fore feet, and hold it as in a hand to its mouth, or take from 

 it small pieces with the other hand like a child eating a cake, and 

 quite as handily ; yet this animal has no opposite thumb on any of 

 the feet, and only short fingers and toes webbed nearly to the claws.

Rhiuaster keitloa (page 317). 



A skeleton of a full-grown female animal in the British Museum, 

 collected by Mr. Jesse in Abyssinia (wanting the hinder horn). 

 The front horn is 16 inches long; it is nearly circular at the base ; 

 the upper half is much more slender, tapering and rather com- 

 pressed at the end. The hinder horn is said to have been about half 

 the length of the front one, compressed and rather sharp-edged, the 

 section in the middle of the horn being about three times as long as 

 wide. 



Compared with the skuU and horns of a younger animal of B. 

 hicomis in the British Museum, received from Mr. Petherick. 



The horns differ in being more compressed and the front horn 

 more slender at the upper part ; but this may depend on the sex. 



The skuU differs from R. hicomis in being much broader in front, 

 at the hinder part of the base of the front horn, and especially be- 

 tween the orbits ; the face is much more bulky and convex on the 

 sides, not flat and tapering in front as in JR. hicomis. The hinder 

 occipital crest is more expanded backwards, the forehead flat and 

 broad behind, but wide, convex, and shelving on the sides under 

 the base of the hinder horns. There can be no doubt of this being 

 a distinct species. 



Length from nasal to condyle 23 inches, from nasal to occipital 

 crest 22 inches, from nasal to orbit 10 inches, nasal to condyle of 

 jaw 19 inches 6 lines, of teeth-line 10 inches 6 Unes, of lower jaw 

 18 inches ; height of skull 18 inches, of ramus of lower jaw 8 

 inches; width at occipital end 9 inches 8 lines, between zygomatic 

 arches 12 inches 6 lines, of forehead 9 inches 6 lines, of nose 

 5 inches 6 lines. 



The skull of B. Tceitloa described by Camper is in the Museum at 

 G^roningen. — Vrolik, Ann. Sci. Nat. vii. p. 24.
