[Apr. 21, tooth I have seen, approaching nearest to the first upper molar of Procyon, and the fourth upper deciduous molar ot Lynogaie. ine tooth is broadest behind. It has one principal external cusp with an accessory one in front of it, and another behind it. ltiere is also a strongly marked internal cingulum. The fourth deciduous upper molar is like the first upper true molar. The fourth lower deciduous molar is like the first lower true molar, but with a larger keel, so that its form is intermediate between that ot the nrst ana that of the second lower true molars. The submaxillary gland is small, but the parotid is exceedingly small. The tongue has a well-developed lytta. All the papillae are small except the flattened papillae, which are a little larger than m Nandinia. The circumvallate papillae are very small, in two rows forming an acute angle open forwards. The liver resembles that of Procyon, except that that part of the right central lobe which is on the left side of the gall-bladder is smaller and not furrowed, and that the caudate lobe is larger. The two anal glands are very peculiar. Each has four small pouches, which recede from its fundus, and are surrounded by glandular structure. The brain * shows but a very indistinctly marked Ursine lozenge, and the calloso-marginal sulcus does not run on into the cranial sulcus. The sagittal gvrus is more complicated than in Procyon. Cercoleptes2.-The'kinkajou is found from Central Mexico down to the Rio Negro of Brazil. Messrs. Godman and Salvin remark that it is not rare in Guatemala, and ranges up to 4000 or 5000 feet. One, which was met with there, feeding on fruit in a tree overhanging the river, and which was wounded, fell into the river, the stream of which it swam in without difficulty. It is an animal easily tamed, living in captivity on oranges and bananas, which it greedily eats. It is not uncommonly found in holes of trees, where it lies concealed during the day, issuing forth at night in pursuit of small animals and birds. Its thick, somewhat woolly fur is much valued, and skins are brought to the market. Dampier in his • Voyages' (vol. ii. p. 59) observes :-"The skin is covered with short, fine, yellowish hair. The flesh of it is good, sweet, and wholesome meat. We commonly skin and roast it, and then we call it Pig, and I think it eats as well." In this animal we again meet with the median nasal groove so generally present in iEluroids ; the head is broad and round, with a short muzzle, the ears short and rounded. The body is long with short limbs, very long and prehensile tail, and the claws very long 1 See the paper on the Convolutions before referred to, p. 11, fig. 1. 2 Viverra caudivolvulus, Pallas in Schreber's S'augeth. iii. p. 453, pi. 1 2 5 B.
