THE SONORAN COLLARED PECCARY 



[Dicotyh's taiacu soiioricnsis) 



The collared peccary inhabiting Arizona and the Sonoran district of 

 Mexico was described in 1897 by Dr. E. A. Mearns as a variety of Cope's 

 D. (iiigulatiis} From the latter it differs by its superior size, relatively 

 larger ears and feet, and paler coloration. In place of being blackish, its 

 colour is greyish, with a sharply contrasting dark dorsal streak. There is 

 also said to be a certain difference in the form of the lower cheek-teeth. 

 It is added that the young are pale reddish brown, with a black dorsal 

 stripe. 



THE COLOMBIAN COLLARED PECCARY 



[Dicotyles tajacu torvus) 



This variety of the collared peccary was named 'rayassi/ torvus in 1898 

 by Mr. O. Bangs,- who regards it as a distinct species. The colour and 

 external characters are the same as in the typical tajacu and its variety 

 angulatus, but the skull is smaller and otherwise different. Among its 

 peculiarities, the skull is characterised by its depression, shortness, and 

 width, and by the evenly rounded and flattened nasal bones. The type 

 specimens were obtained from the Santa Marta district of Colombia. The 

 characters by which this and the preceding races are distinguished appear 

 very trivial.
