 kingdom from the difficulty of preserving them. But few collectors 

 have the necessary skill for removing the perishable portions of 

 the animal and leaving only the shell, and thus we do not often 

 find specimens of crustaceans except in educational museums. 

 Even there the collections are defective, and perhaps there is no 

 portion of zoology which makes slower progress. 



The great naturalist of the province, George Everard Rumpf,

 other, and in his Thesaurus Imaginum Piscium Testaceorum, etc., 

 published in Batavia in 1711, figured a good many crabs, lobsters,
