SOUTH-AMERICAN CANIDiE.

Length of P^i 1-15, of M.1+M.2 1-50, or as 100 to 130. Thus 

 these molars are relatively larger than in C. azarce, but it is not larger 

 than in the C. vetulus of Lund, which probably is (as Burmeister 

 beheves) the same as Wied's C. azaroe. I can, at present, only regard 

 C.fulvipes as a dark variety of C. azarce from the island of Chiloe. 



(3) Canis griseus is a species first named by Gray (P. Z. S. October 

 1836, p. 88) and first described by him in Nov. 1837 (Mag. Nat. 

 Hist., Charlesworth, i. p. 578) thus : — " Vulpes griseus. Pale grey, 

 with blackish tips to the hairs ; legs pale fulvous ; lips, throat, belly, 

 and front of the thighs white ; tail blackish at the upper part of the 

 base and at the tip. Inhabits Magellan. — Captain P. P. King." 



The skin thus described, the type of the species, is also in the

British Museum (No. 55. 12. 24. 239). It is, however, quite imma- 

 ture, and cannot, therefore, by itself serve (in the absence of some 

 very marked character) for the establishment of a distinct species. 

 The skull is in the skin. 



Dr. Burmeister has also described and figured a Dog, which he 

 has entitled C. griseus, Gray (' Fauna Brasiliens,' p. 48, pis. xxv., 

 xxviii., and xxix,, and description 'Descript. phys. Rep. Argentine,' 

 vol. iii. p. 151); and the question arises, Is, or is not, this a distinct 

 species 1 



Now Dr. Burmeister is a naturalist who very distinctly merits our 

 esteem ; he has long lived in South America, and it is impossible
