For the purpose of this catalog we follow Miller, Cabrera, Lydekker, and Flower 
& Lydekker as closely as feasible, using Canis in a rather broad sense and dividing, 
it into subgenera. 
Authors are not entirely in accord in regard to the subgenera of Canis, and it 
is difficult to key these groups unless one uses the factor of geographic distribution.. 
Provisionally, for the purpose of this Host-Catalog, and pending further anatomi- 
cal comparisons by mammalogists, Canis may be divided into the following 
groups (subgenera or genera, according to subjective views as to subgeneric vs. 
generic values) . See #479A.
