Collectors of Specimens.
Students of the crustacea often find the cod a useful assistant collector. Thus the circular crab seems to be a favorite food of cods and rays, and it was chiefly from the stomachs of these fish that some of the older naturalists obtained specimens.
Another hunting ground of the naturalist is the sailing ship which has been in foreign parts. In this way Dr. Clark has been able to add a tiny Chilian crab to the Cornish crustacea. It was obtained by Vallentin on the sides of a bark from Patagonia in a coating of seaweed and barnacles.
The crab itself may become a collector of specimens for the zoologist, for it is often covered with various species of sponges, hydroids and bryozoa. Sometimes the species found thus are such as are not easily obtainable otherwise. One species of crab, indeed (Maia squinado), is regarded in Cornwall as the provider of material for the naturalist.—The Zoologist.
