Article XI. — A SKULL OF DINOCYON FROM THE 

 MIOCENE OF TEXAS. 



By W. D. Matthew. 



Among the valuable specimens brought back l)v Mr. |. W. 

 Gidley from his collecting trip for the American Museum last 

 summer, were the skull and part of the skeleton of an enor- 

 mous carnivore which on extraction from its matrix proves 

 to be a Canid of the Amphicyonine group. It appears to be 

 a very aberrant species of Ditiocyoii, a genus hitherto known 

 by teeth and fragments of the jaw of D. thcnardi descrilied bv

This sijecimen is more complete than any Amphicyonine 

 hitherto described, not only in this country, l)ut in Europe, 

 wJTcre Amphicyons have long been known. The skull and 



' Comptes Rendus de I'Institut, LI 1 1; Bull, des Socictos savantcs (1X62). Another 

 species, Amphicyon goriadiensis Toula, is referred to this genus by Prof. Deperet. Dr. 

 vSehlosser prefers to place it with Hemic yon, probably identical with H. sansaniensis 

 Lartet. It would seem to be an intermediate form, like Dinocyon in the carnassial, 

 like Hemicyon in the tuberculars.
