The pollex and hallux are very well developed. 
In its cranial characters Hemigalea resembles Paradowurus. Its 
bulla is of the same form, but ankylosed into one piece. The par- 
occipital is depending, the mastoid very slightly marked ; there is 
an alisphenoid canal ; and the condyloid foramen is concealed ; but 
the hinder opening of the carotid canal is rather more anteriorly 
situated with respect to the bulla. Its anterior end notches the 
alisphenoid as always hitherto. The postorbital processes are very 
small, that of the malar almost obsolete. When the skull is looked 
at in profile, the dorsum of the muzzle is very concave, and a deepish 
groove runs antero-posteriorly along the junction of the nasal bones. 
There is a peculiar depression or notch in the upper alveolar border 
to receive the apex of 5. 
The teeth are the teeth of Paradozurus ; but the outermost upper 
incisor of each side is more separated from the incisor next it, and 
= are very well developed. P.3 has a distinct internal tubercle ; 
P. 2 
and there is even a very small one to + prop isvery much ex- 
tended vertically, and is received into the upper alveolar notch just 
mentioned. 
Length of head and body about 38'"1; of tail 40!"'6. 
Nothing is said as to any scent-gland in the ‘ Zoology of the Voyage 
of the Bonite ;’ nor do I find any other notice about it. Ina female 
specimen most kindly presented to me by Mr. A. D. Bartlett, and 
which I dissected (portions of its anatomy being preserved in the 
museum of the Royal College of Surgeons), I found superficial folds 
something as in Genetta—two oblique shallow folds extending ob- 
liquely upwards and outwards from near the anus to the vicinity of 
the vagina. The secretion could be squeezed into these folds, just 
as in the specimen I examined of Genetta tigrina. The tongue 
exhibited an oval patch of much enlarged but soft papill on the 
anterior half of the dorsum of that organ. 
A very peculiar plate-like enlargement of the radius is to be found 
on its outer border a little above its styloid precess. Into this are 
inserted the supinator longus, the pronator radii teres, and, espe- 
cially, the large pronator quadratus. 
Hemigalea agrees with Viverra as to the characters so ofter: 
referred to, except Nos. 2 (perhaps), 24, 42, 43, 51, 52, and 53. 
The Binturong (Aretictis), the systematic position of which was 
for a time so much mistaken, is a good example of the small 
value of dental characters as guides to the essential affinity of an 
animal. 
Were it not for Arctogale (which tends to bridge over the dental 
differences between Arctitis and Paradoxurus), the Binturong would 
be an exception amongst the Viverride, something as Proteles is 
amongst the Hyenide. -Arctitis may be confidently affirmed to be 
an aberrant Paradoxure. The animal seems to have been first 
described by Sir Stamford Raffles (as Viverra binturong). in the 
Trans, Linn. Soe, vol. xiii. p. 253.
