but readily visible from the outside. The second premolar re- 

 sembles the corresponding tooth in the other species ; the remain- 

 ing molars are not peculiar. 



Lower Jaio. — Incisors trifid, not crowded. Canines small, 

 with a basal cusp on either side. The premolars are rather small, 

 and have minute points at their base, making them appear as 

 though indistinctly tricuspid. Other molars as usual. 



This species has been but imperfectly described by the authors 

 above cited. Fr. Cuvier's diagnosis is quite incomplete, and 

 would be undistinguishable from that of the smaller form of V. 

 subulatus, had it not been that, from having sent the author 

 the specimens from which the description was taken, Major 

 Leconte w-as familiar with the type and afterwards gave a more 

 exact description of the animal in the w^ork above cited. He 

 however was himself in error in some particulars, especially in 

 making the dentition similar to that of V. subidatns, and in assert- 

 ing that the last false molar of the upper jaw was bi-emarginated. 

 I have before me a large series of specimens, some of which have 

 Major Leconte's name attached, but in none of them have I found 

 any internal basal bi-emarginate cusp as described by him. 



Dr. Bachman's description of V. monticola applies well to S. 

 georgianus, excepting in the measurements, which, in the case of 

 the ear and tragus, are entirely too small in proportion to the 

 size of the body. I have an alcoholic specimen, marked V. monti- 

 cola, in the same handwriting as some other specimens purported 

 to have been labelled by Dr. Bachman, which is beyond doubt 

 S. georgimnis — the ear and tragus being of the usual size.
