168 PROF. ST.-GEORGE MIVART ON THE £LUROIDEA. [Feb. 7, 
The genus Arctictis was instituted by Temminck, who gives it in 
the ‘Tableau Méthodique’ (1827), p.,xxi, in the beginning of his 
first volume of the ‘ Monographie,’ in the second volume of which, 
p- 305, is a full description, with a figure of the skeleton half the 
size of nature, and one of the skull and dentition of the natural size. 
De Blainville, in his ‘Ostéographie’ (Subursus), gives a figure of 
the entire skeleton on pl. 4, of the skull and dentition on pl. 7, 
with some details of the axial skeleton on pl. , of the appendicular 
skeleton on pls. 9 & 10, with the adult and milk-dentition on pl. 11. 
F. Cuvier has figured the dentition in the ‘ Dents des Mammiféres,’ 
pl. 3 d%s. EF. Cuvier also figured the animal (Mém. du Mus. vol. ix. 
p- 44, t. 4) under the name Paradoxurus albifrons; and another 
figure of a semi-adult individual (under the name Binturong) in his 
‘ Mammiferes,’ vol. ii. Valenciennes has also figured it (under the 
name Ictides albifrons) in Aun. des Sc. Nat. vol. iv. p. 57, pl. 1. In 
the ‘ Journal of the Asiatic Society of Bengal,’ vol. xv. 1846, p. 192, 
there is a short but interesting account of the animal. It is referred 
to in 8. Miiller’s ‘ Zoog. Ind. Archipel,’ p. 32. The anatomy of 
this animal has been described by the late Prof. Garrod in P. Z. 8. 
1873, p. 196, with a further note (as to the occasional absence of 
the czecum’) in 1878, p. 142. 
The animal comes certainly from Borneo ; and some say, from 
Java, Sumatra, and Malacca also. 
The ears are tufted, the tail long and, to a certain extent, pre- 
hensile ; and the tarsus and metatarsus are both entirely naked. As 
to the cranium, the bulla is formed on the type of that of Paradow- 
urus, except that the two parts are completely ankylosed in the adult. 
There is an alisphenoid canal, but no pterygoid fossa. The external 
opening of the auditory meatus is small and oval. The postorbital 
processes are very short and blunt (the malar hardly indicated) ; 
and the cranium is not laterally constricted behind them. The 
condyloid foramen is concealed. The cranial ridges are not largely 
developed ; but the paroccipital process depends, and the mastoid is 
rather marked. The carotid canal opens posteriorly at the middle 
of the inner side of the auditory bulla, while anteriorly it notches 
the alisphenoid. There is no foramen or fissure in the floor of the 
auditory bulla’s anterior chamber ; but there is a very deep pit (to 
receive the cornu of the hyoid) on the side of the bulla just behind 
the external auditory opening. The palate is greatly prolonged behind 
the hindmost molars. The angle of the mandible is very small. The 
zygomatic arches present a rather concave instead of a convex out- 
line medianly when viewed from above or below. The premolars 
and molars are small and separated one from another by small but 
marked intervals. The number of teeth varies slightly, as either 
2 . “4: 
on may be wanting, and (according to Raffles) there may be 
six teeth in the lower jaw; i. e. 5+ is probably present sometimes, 
? That there is much variation as to this part is shown by the record, in 
vol. xv. p. 193 of the ‘Journal of the Asiatic Society of Bengal,’ that the cacum 
is half an inch long.
