From this Sunfish I obtained a number of curious PARASITES: 
which answered the description and figure of Pennella filosa 
given in Cuvier’s Animal Kingdom.* The head and neck of 
these torturing enemies had penetrated from two to three inches 
into the sides of their victim—indeed, in some places I think the 
most anterior parts must have bored entirely through the flesh, 
as the belly averaged only two inches in thickness. The bushy 
posterior portions when seen hanging from the body of the fish, 
had much the appearance of pieces of seaweed. In extracting 
some from their burrows the heads were broken off and blood 
trickled abundantly from theruptured parts. A perfect specimen 
(in alcohol) measures as follows :— 
Total length when straightened out, 6 inches ; 
Length of portion in fish, about 2°6 inches; 
Length of plumose portion, 1 inch ; 
Length of the two filaments arising from near the poste- 
rior end, 5°8 inches.
