carries the second molar in an excellent state of preservation, and 

 exhibits the alveolus for the last molar and a portion of that of 

 the first. The species can be readily distinguished from V.palustris 

 by its smaller size and the less laterally compressed character of 

 the second molar. 



Procynodictis vulpiceps, gen. et. sp. nov. 



This genus is proposed upon two specimens in the Museum 

 collection, one of which (No. 2514) includes one upper and both 

 lower jaws, together with the greater part of a hind foot, and the 

 other (No. 2506) includes a part of the skull and the greater 

 portion of the right fore foot. Besides these there are two frag- 

 ments of jaws (Nos. 1895 and 1995) which we refer to the same 

 species. 



The dental formula is the same as in Viilpavus and Cynodictis, 

 there being but two true molars above, and the systematic posi- 

 tion of the genus is entirely intermediate between these two. In 

 the structure of the superior molars it agrees with Vulpavus in 

 that there is a great extension of the antero-external part of the

 as in the modern Dogs, but the great antero-external extension is
