developed in the Viverride than in the Felide. Comparing the 
cervical vertebrze of the Civet with that of Felis catus, it may be 
remarked that while the plate-like transverse processes of the third 
vertebra are no larger (if not somewhat smaller) relatively in the Civet, 
those of the 4th, 5th, and 6th vertebre are relatively larger; the 
neural laminze are more concave dorsally, and the hypapophyses are 
much stronger, and the hyperapophyses more marked. ‘The Genet 
is more cat-like; but, in the specimens examined, the distal ends of 
the plate-like transverse processes of the 4th, 5th, and 6th vertebre 
project more preaxiad than in the Cat or Civet. Paradowurus pre- 
sents characters intermediate between those of the Cat and the Civet. 
Arctictis is very exceptional as to its cervical vertebrae, their 
transverse processes being so little extended antero-posteriorly, the 
plate-like parapophysial parts of each transverse process of even the 
5th and 6th cervical vertebree being very little broader than the diapo- 
physial part. The distal ends of the transverse process of the vertebrae 
posterior to the third are not all produced preaxiad distally ; never- 
theless the hypapophyses are more marked than in Felis catus. There 
is a distinct rib, with both capitulum and tuberculum, on the left 
side, and a less perfect rib on the other side, of the 7th cervical 
vertebra of the specimen of Arctictis, No. 1200 B, in the collection 
of the British Museum. 
Seventh cervical vertebra of an Aretictis binturong, showing the perfect rib 
on the one side. 
Cryptoprocta differs remarkably from Aretictis in the greater 
antero-posterior extent of its plate-like transverse processes and in 
the preaxiad extension of the distal ends of those of the 3rd, 4th, 5th, 
and 6th vertebree. There are marked hyperapophyses to the first 
two or three vertebra. These processes, as also the cervical meta- 
pophyses, are very distinct on the 2nd, 3rd, 4th, 5th, and 6th verte- 
bree of some Herpestes'. In Felis catus hyperapophyses are not 
only developed above each postzygapophysis of the axis, but these 
become more marked on the 3rd cervical vertebra, less on the 4th,
