MAMMALS CANIDAE CANIS LATRANS. 



117 



The present skull is exactly similar, except in being a little smaller, to that of the specimen 

 upon which Dr. Woodhouse founded his supposed diminutive species of Coyote, under the name 

 of Canis frustror. 



The following table of measurements will illustrate the above remarks. In addition to the 

 absolute dimensions, a column of proportion gives the width of the skull in terms of hundredths 

 of the length from the anterior extremity of the bony alveolus of the incisors to the posterior 

 portion of the occipital condyles. 



Measurements and comparison of the skulls of prairie wolves. 



Length of skull taken from the anterior edge of the alveolar processes of the Incisors to the most backward portion of 

 the condyles. 



Lower jaw measured f:om the anterior border of the incisive alveolar to the posterior edge of condyle. 



NOTE. The second columns under each head gives the length or width in termg of hundredths of the distance from inci 

 sive alveoli to the most posterior portion of the occipital condyles.
