The general tendency is to put the larger specimens of Canis 

 with the species C. dims Leidy.* Prof. W. B. Scott in his 

 new book (16.204) mentions C. dims and C. indianensis, 

 which he considers synonymous. It seems quite fitting, there- 

 fore, that the first seven specimens, including group I of the 

 Peabody Museum fossils, be placed under C. dims Leidy.

* J. A. Allen (1.49) was probably the first to point out the precedence of 

 the name C. dims over C. indianensis (10.368), which was a later name 

 applied to the type to which the preoccupied name of C. primcevus (7.200) 

 was first given by Leidy.
