Genus CANIS, Linn.* 
Following Flower’s classification this genus is taken to include 
all the existing Canoids, with the exception of Lycaon, Icticyon, and 
Otocyon ; it also includes the fossil genera Galecynus, Owen, and 
Lycorus, Bourguignat. 
Dentition—In typical forms the dental formula is I. as €: = 
Pm. A M. : ; in some aberrant forms (Cyon), however, the true 
molars are 2 5; and in the fossil C. (Lycorus) nemestrinus the pre- 
molars are reduced to =: The ee embracing this range of 
variation” will be I: 5. U: ; legit oe gaan AE a There is a great 
amount of sean in ae relative proportions of the different 
cheek-teeth ; and in the degree of development and position of the 
inner cusp of the lower carnassial*. There is no entepicondylar 
foramen to the humerus.

44739. Cranium and mandible, wanting several teeth; from Hutton 
Cave, Somersetshire. ‘This specimen is remarkable for the 
circumstance that the first upper premolar of the left side 
(of which the anterior half is broken away) is of an elon- 
gated form like pm. 2, and is inserted by two distinct fangs. 
The first three premolars are in contact with one another. 
In the mandible pm.1 has only a single root; but the 
three preceding teeth are relatively long, and are in 
contact with one another.

2 In C. cancrivorus the molars are =e 5 = ; and Filhol has shown that in the 
long-jawed domestic races like the greyhound ™ 3. is occasionally present, while 
in the short-jawed races like the bull-dog m. 3 is is sometimes absent.
