142 PROF. ST.-GEORGE MIVART ON THE ZLUROIDEA. [Feb. 7, 
in profile, it differs from the skulls of the varieties F. borealis, F. 
canadensis, F. rufa, and F. maculata in that the part between the 
orbits is more raised and convex, and the nasal bones extend back- 
wards beyond the nasal processes of the maxille. 
Considering the length of time during which we have had power 
in India, it is remarkable that our collection of Indian Cats should 
be so imperfect as it is. I am, however, not without the hope of 
being hereafter able to exhibit here a new collection of the skins and 
crania of these animals. The species known as F. dengalensis espe- 
cially requires investigation, as, if its range of variation both in size 
and markings is not very extensive, several distinct species must be 
included under that name. 
Amongst African Cats that described by Lesson’ under the name 
F. senegalensis was probably but a young Serval. There is unfor- 
tunately no specimen of it in the Paris Museum ; and the type was a 
cat living at the hospital of Rochefort-sur-Mer. We have as yet, so 
far as I know, no specimen of F’, colocollo in this country ; and we much 
need more skins and skulls from America to help us to determine 
the value of the forms distinguished as F. tigrine, F. mitis, and F. 
macroura. 
The second Ailuroid family, the Viverride, presents a great con- 
trast to the first in the great variety of the forms it contains. In- 
stead of being unable to divide it into subfamilies, the difficulty is to 
avoid making too many. Two subfamilies, Viverrine and Herpes- 
tine, must, I think, be instituted for the Viverrine and Herpestine 
sections of the group. In the former must stand Viverra, Viverri- 
cula, Fossa, Genetta, Prionodon, Poiana, Paradoxurus, Arctogale, 
and Hemigalea. In the latter I would place Herpestes, Helogale, 
Cynictis, Bdeogale, Rhinogale, Crossarchus, and Suricata. 
As to Nandinia, Arctictis, and Cynogale, arguments are by no 
means wanting in favour of the erection of each of these three genera 
into a distinct subfamily. I hesitate, however, so far to multiply 
groups of that rank ; and I would retain them all, at least provision- 
ally, amongst the Viverrine. 
The genera of this subfamily seem to group themselves in two sets 
(as was indicated by Mr. Turner *), one set being that of the Civets, 
the other that of the Paradoxures, as follows :— 
A. Viverra, Viverricula, Fossa, Genetta, Prionodon, and Poiana, 
B. Paradoxurus, Arctogale, Arctictis, Hemigalea, Nandinia, and 
Cynogale. 
_ The subfamily Herpestine seems divisible into two sets—one (A) 
including Herpestes, Helogale, and Cynictis ; while the second set (B) 
will comprise Crossarchus and Suricata. 1 cannot certainly deter- 
mine to which set Bdeogale and Rhinogale should belong till more 
of their anatomy is known. 
It is to the latter set that I regard the Hyenide as specially 
allied, while Cryptoprocta (in spite of its claws and dentition) seems
