though I have never seen it. —~, if present, is very small, one- 
rooted, and much less than half the size of Mt M1 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. 
P+ is like that of Paradowurus, 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; 7-2 
is similar but smaller ; and ** may be wanting, but if present is long 
and conical. 5-1 1S WANG,” pop eras and es conical teeth, 
increasing in breadth progressively backwards. 3,5 is much as in 
Paradoxurus, but is broader in proportion to its length. The talon 
does not form quite half the tooth. 3,5 is more rounded than 
generally in Paradoaurus ; it is not much smaller than a. As to 
the milk-dentition, the deciduous upper sectorial (?-8) ig mueh 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

Pr The infraorbital foramen opens above ——. == does not bite

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, however, so much the general appearance and 
character of the Paradoxures (with which it was at first associated) 
that I feel compelled to place it in proximity to them, in spite of the 
very exceptional character 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 Paradowurus. 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 by him as Paradoxurus? 
binotatus (P. Z.S. 1832, p. 68) and P. hamiltonii (P.Z.S. 1852, 
p- 67, and Illus. Indian Zool.). It is the P. binotatus of Temminck 
(* Monographie,’ vol. ii. p. 336), who figures the skull (pl. 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, ‘ Ostéographie,’
