 External Characters. — Much larger than Cerdocyon grisens, and 

 much more strikingly colored. Head pale rufous, varied with gray and 

 black-tipped hairs, the latter more abundant on the face and upper part 

 of cheeks than elsewhere ; back gray strongly varied with black, which 

 is the prevailing tint over the median region from the shoulders to the 

 tail ; underfur fulvous gray ; sides more fulvous, and less varied with 

 black-tipped hairs, passing into strong fulvous or light rufous on the sides 

 of the neck and lower part of sides ; chin dusky ; ventral surface yel- 

 lowish white, passing into pure white on lower part of abdomen ; ears 

 externally deep rufous with a slight admixture of black-tipped hairs over 

 the apical portion, internally yellowish white ; fore limbs bright rufous 

 externally, fulvous internally ; thighs deep rufous red, paler rufous on the 

 legs externally and fulvous internally ; upper surface of tail strongly 

 black on the basal fourth, and for three or four inches at the tip and for 

 six or eight inches on the sides ; middle portion pale fulvous with an 

 abundance of black-tipped hairs ; lower surface pale rufous for its whole 

 length, except for the long black tip. 



This beautiful species is represented by only a single flat skin, obtained 

 by Mr. J. B. Hatcher in the " Southern Andes of Patagonia." Cerdocyon 

 magellanicns is undoubtedly closely related to Cerdocyon cnlpccus (Molina), 

 to which the present specimen may possibly be referable — a point impossi- 

 ble to establish in the absence of other material, especially from Tierra 

 del Fuego, the type region of C magellanicns. The present specimen, 

 however, agrees exceedingly well with Mivart's colored plate of the type. 

 Mr. Brown's manuscript notes contain the following reference to the 

 present species : 



" A large fox, Canis magellanicns, is found in considerable numbers on 

 Tierra del Fuego, and is reported from the Andes on the mainland. This
