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 from the anterior border of the incisive alveolar to the posterior edge of condyle.
