356 DR. ST. G. MIVART ON THE ARCTOIDEA. [Apr. 21, 



tooth I have seen, approaching nearest to the first upper molar of 

 Procyon, and the fourth upper deciduous molar of Cynogale. The 

 tooth is broadest behind. It has one principal external cusp with 

 an accessory one in front of it, and another behind it. There 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 of the first and 

 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 in 

 Nandinia. The circumvallate papillaj 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-njarginal sulcus does not run on into the cranial 

 sulcus. The sagittal gyrus is more complicated than in Procyon. 



Cercoleptes". — 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 umcommonly 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 ^Eluroids ; 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
