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 in the more northern and western counties, 

 in the wooded districts, where they prey upon birds and the smaller quadrupeds. 



FAMILY VTII. PHOCID^. 



Teeth various. Feet short and Jin-shaped, not free, the phalanges being enveloped in the 

 teguments. Hind feet horizontal. Rarely leave the water. Piscivorous. 



Obs. 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. Mammce two, pectoral. Tail short and thick. Teeth of three kinds : 

 Incisors, | ; canines, | ; cheek teeth, |J = 34. Cheek teeth trenchant, many-lobed. 



Obs. 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 vmter 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."
