Show 108 DR. ST. G. MIVART O N [Mar. 18, As to the teeth, in spite of the imperfection of the specimen figured (pi. xxix. fig. 2), it is plain that P ^ is rather smaller compared with M. l-r-M.2 than even in his C. vetulus. Burmeister himself gives (Reise durch La Plata, p. 407) the proportions as F J = 8, M. 14-M. 2 = 13, or as 100 to 162. Lund gives no figure of the dentition of this species proposed by him. Thus altogether I think we should provisionally identify, as Burmeister was at first inclined to do, these two species of Lund, and they may turn out to be, as Burmeister believes Lund's C. vetulus to be, identical with the C. azarce of Wied. The coloured plate given by Lund might certainly stand for a pale example of C. azarce, and it is higher on its legs than the C. vetulus of Burmeister or the Fig. 4. Surfaces of molar teeth of Lower jaw of Canis parvidens Canis parvidens (right side). (right side). British-Museum skin. The form called C. vetulus by Burmeister must not be so called any longer, and it therefore needs a distinct designation. I propose to call the British-Museum skin and skull - 4 4 . 3. 7. 3 & 821 A-(as the type of the species or variety) C. parvidens, from its most characteristic feature ; and for the present I regard the C. vetulus of Burmeister as probably identical with m y C. parvidens (figs. 3 & 4). In 1869, Philippi published a paper (Arch. f. Natur. xxxv. vol. i. pp. 38-51) referring to the publications of his "much honoured friend" Burmeister. He seeks to know (p. 47) whether the Chilla (C. azarce of Chili), C. patagonicus, and C. fulvipes are or are not all the same species ; and in the second place, whether the animal from Chile (the Chilla) is identical with C. azarce or rather with Bur-meister's C. gracilis. |
