authority of Indian traders, that seals have heretofore been seen on the borders of the Lake, 
though the circumstance is one of rare occurrence. A species of seal was captured, some 
years since, near Lynn, Massachusetts, which is mentioned in the newspapers as being beau- 
tifully spotted, especially on the under side, and referred to the P. vitulina. In August, 
1824, a seal was exhibited alive in New-York, which had been taken in a seine in the Che- 
sapeake, near Elkton, Maryland. Dr. Mitchill, who saw it, supposed it to be the P. vitulina; 
although, as he states in a newspaper paragraph, “in the written account, (alluding to a 
“description he had drawn up in 1818 of a seal taken near Amboy,) there is no note 
‘of the natural mark in the breast of the present creature, nor of more than five claws on 
“the fore feet.” What this natwral mark could have been, or what is meant by more than 
five claws, must be left to conjecture, or to await the examination of another individual.

Form and habits of the preceding, but the head is furnished with a dilatable hood. Teeth 
30 ; four incisors above, and two beneath. 
Under the barbarous name of Mirounga, Mr. Gray has proposed to group together several 
species of this family, which are characterized by “ the nose elongated into a trunk, and the 
“teeth with simple roots.” In the present state of our knowledge of this family, we prefer 
the name and characters noted above.
