General Assembly, to encourage the destruction of wild-cats ; and in 1745, it was still found 
necessary to renew this act. At present, it is believed that they are entirely extirpated from 
this and the adjacent counties. They are still found inthe more northern and western counties, 
in the wooded districts, where they prey upon birds and the smaller quadrupeds. 
FAMILY VII. PHOCID:. 
Teeth various. Feet short and fin-shaped, not free, the phalanges being enveloped in the 
teguments. Hind feet horizontal. Rarely leave the water. Piscivorous. 
Oxs. Some of the species are of great bulk, and all contribute in various ways to the wants 
of mankind. I am acquainted with the type of but one genus within this State. 
GENUS PHOCA. Cuvier. 
Head rounded. No external ears. Eyes very large. Feet with five toes, connected by a 
thick membrane. Mamme two, pectoral. Tail short and thick. - Teeth of three kinds: 
Incisors, &; canines, 2; cheek teeth, +4 = 34. Cheek teeth trenchant, many-lobed. 
Oss. To this genus, as restricted by Cuvier, belong at present about thirteen species, more 
or less perfectly indicated. The difficulty of examining the individuals of this family must be 
very great. A recent English writer states, that “little more is known of the Common Seal, 
“though an inhabitant of our own seas, than of those which are met with in the most distant 
“latitudes.”
