which is five or six feet long, a most dangerous antagonist when the fisherman comes in direct conflict with it.
The hand-fishes of the tropics are very small, but their grotesque appearance and hand-shaped fins, suited for creeping, make them very

Nor ought the lump-fish (Fig. 21) to be omitted in this enumeration; for, although it is not specially remarkable in its general aspect, it is very remarkable in at least one portion of its structure. It has
