though I have never seen it. ^, if present, is very small, one- 

 rooted, and much less than half the size of '-^. —^ is much like 

 the same tooth in Paradoxurus, but is less transversely extended in 

 proportion to its length ; it has three tubercles and three roots. 

 -^- is like that of Paradoxurus, save that it is modified by the very 

 great reduction of the foremost and hindmost outer cusps, which are 

 each connected by a ridge (the cingulum) with the largely-developed 



inner cusp. -^— is a trihedral tooth with rounded angles ; -^— 

 is similar but smaller ; and — ^ may be wanting, but if present is long 

 and conical, p-^ is wanting, p-g, p-g, and p-j are conical teeth, 



increasing in breadth progressively backwards, j^ is much as in 

 Paradoxurus, but is broader in proportion to its length. Tlie talon 

 does not form quite half the tooth, jj-5 is more rounded than 

 generally in Paradoxurus ; it is not much smaller than p-^. As to 



the milk-dentition, the deciduous upper sectorial ('^-) is much more 

 sectorial than is the permanent sectorial tooth. It is very narrow 

 from side to side, having either a mere rudiment of an internal cusp 



or none. -^— is quite like — ^, g-^ is rather more sectorial than is 

 =— . The infraorbital foramen opens above ^. p-^ does not bite 



at all against — ^ but against ^^ and -^—. 



The pollex and hallux are very well developed. The claws are 

 strongly arched and pointed {cf. fig. 14 C, p. 192), and more or less 

 retractile. 



There is a prescrotal gland, which exudes its secretion into a naked 

 cutaneous invagination placed, like a vulva, in front of the anus. 



Arctictis agrees, so far as I can ascertain, with Viverra, except 

 in the characters numbered 9, 17 (sometimes), 24, 28 (sometimes), 

 33, 37, 43, 45 (often), 47, and 50. 



The next form is one the nature and affinities of which are to me 

 doubtful. It has, liowever, so much the general appearance and 

 character of the Paradoxures (with which it was at first associated) 

 that 1 feel compelled to place it in proximity to them, in spite of the 

 very exceptional ch.aracter of the auditory region of its cranium. 

 Indeed the non-ossification of parts of its bulla may be taken as a 

 great exaggeration of that separate, movable condition of its hinder 

 chamber which we have seen to be the case in Paradoxurus. Its 

 claws are like those of the last-mentioned genus, as also the naked 

 condition of its tarsus and metatarsus. 



The genus Nandinia was instituted by Gray (P. Z. S. 1864, 

 p. 529) for the species previously described bv him as Paradoxurusi 

 binotatus (P. Z. S. 1832, p. 68) and P. fiamiltonii (P. Z. S. 1852, 

 p. 67, and Illus. Indian Zool.). It is the P. binotatus of Temminck 

 (' Monographic,' vol. ii. p. 336), who figures the skull (pi. 65. figs. 7, 

 8, & 9) and refers to it in his 'Esquisses Zool.' p. 119. Its external 

 form is represented in Gray's ' Illustrations of Indian Zoology.' 



The skull and teeth are figured by De Blainville, ' Osteographie,'
