Salado, as well as in the lakes that border them ; and is also found 

 further south along the rivers of the Provinces of Buenos Aires and the 

 Banda Orientale, sometimes as far as the mouths of the rivers, near 

 where they enter the ocean. The only record I know for its occurrence 

 in the Straits of Magellan is that by Thomas (P. Z. S., 1889, p. 198, 

 footnote, and p. 199, in text), who states that one of Dr. Coppinger's 

 specimens taken in the Straits of Magellan, and first referred to L.felina, 

 proved on a later examination of the skull to be really L. paranensis. 

 Its range thus meets that of L. felina, and hence occurs on the coast and 

 in the rivers of Southern Patagonia. 



Family CANID^. 



The South American Canids are more or less unlike typical representa- 

 tives of either Cains'^ (C lupus <gxo\x^^= Lupus Frisch, 1775) or Vulpes, 

 and various names have been proposed for their generic or subgeneric 

 designation. For the twenty species and subspecies which seem more or 

 less well entitled to recognition at least five generic or subgeneric names 

 (excluding synonyms) have been proposed. Of these Speothos Lund 

 {id>2,9= Icticyon Lund, 1843, apud T\\om^.s) is widely different from any 

 other member of the family, and was formerly referred by some authors 

 to the Mustelidae; it includes the "Bush Dog" {S. venaticus) of Brazil, 

 and one or more extinct cave forms from the same region. 



Another very distinct group is that to which Matthew and Wortman 

 intended to apply the name NotJiocyon, but which, through the peculiar 

 circumstances attending the original publication of the name, is not avail- 

 able in this connection. The type of Nothocyon'^ was intended to be 



' By the process of elimination Canis Linn., 1758, is restricted to C. faDiUiaris, the first of the 

 seven species given by Linnseus under Canis. These species are : 



1. familiaris, type of Canis, s. s., Ham. Smith, 1840; Gray, 1868. 



2. lupus, type of Lupus F"risch, 1775 ; also of Oken, 18 16, Gray, 1868, etc. 



3. hyana, type oi Hycena Brisson, 1762. 



4. vulpes, type of Vtdpes Frisch, 1775, and of several later authors. 



5. alopex,= C. vulpes Linn. 



6. lagopus, type of ^/^/ir.r Kaup, 1829, diV\d o{ Leucocjou Gray, 1868. 



7. aureus, type of Titos Oken, 1816; Vulpicatiis Blainville, 1837; Sacalius Ham. Smith, 

 1839; Oxygoi'is Yio^gsor^, 1841 ; .? Z?<'/'«/?<.r Gervais (ex Blainville), 1855. 



^ Nothocyon was first proposed by Matthew (Bull. Am. Mus. Nat. Hist., XH, pp. 20, 62, 

 March 31, 1899) without characterization (/. c., p. 20), although later in the same paper (/. c., p. 

 62) three fossil species, previously described by Cope, from the John Day (Lower Miocene)
