Desmarest, in his ''^ Mammalogie^^'^ includes all 

 the varieties of this species under three grand 

 divisions. 



" I. Les matins. Head more or less elongated ; 

 parietals approximating: condyles of the lower 

 jaw on a line with the superior molars. 



" 2. Les espagneuls. Head moderately elonga- 

 ted ; parietals not approximating from their com- 

 mencement above the temporals, separating on 

 the contrary, and expanding so as to increase the 

 cerebral cavity and frontal sinuses. 



" 3. Les dognes. Snout more or less shortened ; 

 cranium elevated; frontal sinuses considerable; 

 condyles of the lower jaw placed above the line 

 of the superior molars." 



In detailing the characters of the common bull 

 dog, {Cams molossus, Linn. Gmel.) he omits one 

 of the most principal traits, viz. in this variety, 

 the inferior incisors and the lower jaw project 

 beyond the superior teeth and jaw. 



For a detailed account of the varieties of the 

 domestic dog, see F. Cuvier's papers, published 

 in the anal, du mus. d'hist. nat.

 much more savage or imperfectly reclaimed animal than the 

 eommon dog.'"*
