["With regard to the relations of the Sivalik species to M. cidtridens^ 

 M. latidens, and M. ixdmidens, nothing can be said at present, as, 

 with the exception of an imperfect specimen of the milk- canine, 

 neither this tooth nor the incisors of the Sivalik species have yet 

 been discovered. M. pahnidens^ however, could he distinguished 

 by the size and form of the two lower premolars.] 



Felis, sp. ? 



The specimen consists of a cranium* deficient in the facial por- 

 tion in front of the orbits. The zj'gomatic arches, brain- case, and 

 its base are beautifully preserved. The specimen is not mentioned 

 in the ' Palseontological Memoirs,' but it is entered as Felis cris- 

 tata (?) in the catalogue of the British Museum, and, as I am in- 

 formed by Mr. Davies, comes from the Sivrdik Hills. The skull 

 belonged to an animal considerably larger than Felis cristata, and 

 of about the same size as the larger varieties of the Eoyal Tiger. 

 The Fagittal crest (slightly damaged posteriori}-) is much thicker
