developed in the Vivernrhe than in the FeUdce. Comparing the 

 cervical vertebrae of the Civet with that of Felis cuius, it m.ay 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 vertebrae are relatively larger; the 

 neural laminae 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 vertebrae 

 project more preaxiad than in the Cat or Civet. Pnradoxiirus 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 vertebrae 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 oi Arctictis, No. 1200 b, in the collection 

 of the British Museum.

Cryptoprocta differs remarkably from Arctictis 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 vertebrae. There are marked liypcrapophyses to the firs-t 

 two or three vertebrae. These processes, as also the cervical met.*;- 

 pophyses, are very distinct on the 2nd, 3rd, 4th, oth, and 6th verte- 

 brae 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,
