have been made, the mollusks can be preserved in as small a 

 quantity of alcohol as the bulk of the animal. 



Care should be taken in preparing shells of mollusks for ship- 

 ment to avoid injury or breakage. Delicate specimens should 

 be wrapped in paper or other soft material. Place a label written 

 in pencil with each lot, giving locality, date, and collector.

When packing small living mollusks, wrap the label in cloth to 

 prevent the animals from eating it. 



For shipping, all should be packed in wooden boxes with paper, 

 excelsior, clean, dry grass, or other packing to keep them from 

 jostling. In tropical countries fragile specimens may be packed 

 in joints of dry bamboo (which make excellent mailing tubes). 

 Empty cartridge shells also make good containers.
