ME, O. THOMAS OK NEW SPECIES 



In the lower jaw the incisors are very small, the two middle ones nearly 

 horizontal, slightly spatulate, and each with one external secondary cusp ; 

 second and third pairs, and the canines, each consisting of one large an- 

 terior and one small posterior cusp. Premolars and molars all about equal 

 in height, and very similar in general form to those of Centetes ; but the 

 posterior ledge of the last molar has a well developed cusp, half the height 

 of the main anterior one, so that externally this tooth appears to be twice 

 the size of any of the others. 



Skull with united nasals, a ring-shaped tympanic bone, and a well- 

 marked lacrymal canal. Clavicles well-developed. Tibiae and fibulae 

 anchylosed together for their distal halves. 



Vertebral formula — cervical 1 , dorsal 16, lumbar 5, sacral 2, and 

 r 44 in ilf. longicaudata.
