188 PROF. ST.-GEORGE MIVART ON THE ZLUROIDEA. [Feb. 7, 
G. elegans is represented in the British Museum by skins and 
skulls ; and there is a skeleton in the Royal College of Surgeons. 
The fur is of one colour, save that the tail is ringed with black, 
the hair notannulated. The length of the head and body is about 
45''*2, and that of the tailis 30’°5. The muzzle seems rather obtuse. 
The claws are long, but considerably,curved, The tarsus and meta- 
tarsus are covered beneath with sparse short hairs, or are more or less 
inclined to be bald, but are not so as in Galidictis. 
The skull is very like that of Galidictis ; but the muzzle and palate 
are narrower relatively, aud the mandibular symphysis is much 
shorter. There is, again, no alisphenoid canal. The condyloid 
foramen is exposed. The palate is flat, and not concave posteriorly 
as in Galidictis. The zygomata are not quite so much arched out- 
wards. The auditory opening is a more elongated oval. In other 
respects the skull is as in Galidictis. 
As to the dentition, it is quite like that of Galidictis, save that 
the canines are smaller, especially the lower ones, the external inci- 
sors less preponderating. *** is smaller relatively. ™? may be 
quite small and placed within the hinder part of “=. 
The preparation No. 2147 B in the museum of the Royal College 
of Surgeons shows that there is a single pair of rather large anal 
glands ; and the anus does not seem to open into any cutaneous de- 
pression. 
The two other species described by Isid. G. St.-Hilaire differ con- 
siderably from G. elegans, as that author himself pointed out, and as 
has been more decidedly indicated by Dr. F. A. Jentink?. I have not 
had any opportunity of examining G. concolor; but, on account of 
its declared resemblance to G. olivacea* (which is represented by 
skins, skulls, and a skeleton in the British Museum), it must be 
separated generically from G. elegans if G. olivacea is to be so sepa- 
rated. Now two courses seem to me feasible: one is to institute a 
new genus for the species ol/ivacea and concolor; and the other is to 
unite Galidia and Galidictis in a single genus. But the differ- 
ences between the last-named genus and G. elegans seem to me to be 
as great as those which separate Cyna@lurus from Felis; and as 
G. olivacea (and, as L infer, concolor) seems to me to differ as much 
from G. elegans as does this last from Galidictis, the more reason- 
able course seems to me to be to separate them, which I now accord- 
ingly propose to do under the generic name Hemigalidia. 
In external characters Hemigalidia differs from Galidia in the 
non-annulation of the tail, in the more pointed muzzle, and especially 
in the less arched (more Herpestine and less Viverrine) form of its 
claws (cf. fig. 14, 5 and x, p. 192), 
In the skull the bulla is rather more decidedly Herpestiform than 
in Galidia. The carotid foramen (for the entrance of the carotid 
artery) is more conspicuous ; the hind part of the palate is not so
