tological Memoirs'*, these have been labelled " Canis,'^^ but have a 

 note of interrogation added. 



The skull indicates an animal of nearly the same size as the 

 Civet ( F. civetta). The third premolar, which is proportionately- 

 larger than the corresponding tooth in the latter, consists of a stout 

 triangular crown, and presents no division into accessory lobes ante- 

 riorly or posteriorly. The cingulum is well pronounced, and sends 

 up a ridge anteriorly, which, meeting with its fellow from behind, 

 divides the crown into two parts, of which the external is much 

 more convex than the internal. The sectorial is like the corre- 

 sponding tooth in the Civet, but proportionately larger. The ante- 

 rior of the two lobes into which its blade is divided is thick and 

 conical, with a small accessory lobule in front, and is mapped off by 

 a notch from the posterior lobe. The internal tubercle is stout and 

 strong, and separated by a deep valley from the outer lobes, as in 

 the Civet. The first tubercular is triangular and tricuspid, and is a 

 little larger than the corresponding tooth in that species. The two 

 subequal outer cusps are ground down into flattened crescent-shaped 

 disks ; and the inner cusp is separated from them by a deep pit. The 

 second tubercular is proportionately longer laterally and narrower 

 .antero-posteriorly than the corresponding tooth in the Civet. 



There are only three other fossil species of Viverra which have 

 been made out with any thing like certainty, viz., V. antiqua and 

 V. exilis of De Blainville and V. sansaniensis of Lartet. The last 

 two are known by their lower jaws only, so that I am not in a 

 position to compare them with the present fossil. It is readily distin- 

 guished from V. antiqua by the proportionately smaller size of the 

 teeth, especially of the hindermost tubercular, in the latter species f. 



In the following measurements the skull of the Civet selected for 

 comparison is a little larger than the fossil : —
