As to the teeth, in spite of the imperfection of the specimen figured 

 (pi. xxix. fig. 2), it is plain that P- 4 is rather smaller compared 

 with M. 1+M. 2 than even in his C. vetulus. Burmeister himself gives 

 (Reise durch La Plata, p. 407) the proportions as P^ = 8, M. 1+M. 2 

 = 13, or as 100 to 1 62. 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. azaree of Wied. The coloured plate 

 given by Lund might certainly stand for a pale example of G. azaree, 

 . and it is higher on its legs than the G, vetulus of Burmeister or the

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 

 — 44. 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 my G. 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. azaree of Chili), G. patagonicus, and G.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. azaree or rather with Bur- 

 meister's G. (jracilis.
