ood resting in the library, you need your copy to carry to 
ae Or 32h. dies beatl Was I ever glad to be able to separate 
brittle stars, sea cucumbers, sponges, and some of the puzzling — 
crabs! I like echinoderms and "eureka" all I need (for now) are in 
this one book by Dr. Voss. This is a book for anyone who is she ed 
about sea life along the shore and off the Caribbean islands. an 
SEASHORE LIFE, poisonous or stinging species are each marked wi a 
skull and crossbones; its danger and doctoring are described. 
There is a most friendly preface from author to reader; four pages 
on COLLECTING & PRESERVING -- really super and covering those little 
known creatures so hard to preserve -- ending with a caution for 
conservative collecting action. The author reminds us of the plea- 
sure of looking up the meaning and enjoying the scientific names as 
we move along in our hobby and progress to the full use of then. 
Another great feature is that each drawing again gives the scienti- 
fic and the common name.

THE MOLLUSK 15(2):2 February 1977 
CORBICULA, SPREADING PEST 
A price sheet from a California firm supplying laboratory material 
lists Corbicula leana Prime, 1864 (Lea's Asiatic Clam) at 15¢ each 
for small, 45¢ for large. To quote Dr. David Stansbery, this insures 
that every State has its fair share of Corbicula. Brought from the 
Orient in the 1930's, it is one of the most costly molluscan intro- 
ductions in recent times. It has caused much trouble in irrigating 
ditches, gravel operations, highway construction, etc. (has clogged 
the intake pipes of many water systems and caused failure of concrete 
in construction. It is working its way south from central Florida 
and north from central Ohio). This is a conservation problem in re- 
verse. Marc Imlay suggests that each member write to the Secretary 
of Interior, Cecil D. Andrus, to Dr. Juanita Kreps, Secretary of 
Commerce, and to your Senator and Representative, to have this pest 
mollusk put on the "Prohibited Species List" under the Lacey Act. 
This would at least halt its spread by commercial means.

Among other species of introduced mollusks that have become pests 
are Corbicula manilensis (Philippi 1844) which has become very wide- 
spread, and Corbicula fluminea. The freshwater gastropod, Tarebia 
granifera (Lamarck, T8716), originally from China, is now established 
in Florida and southern Texas. It serves as the intermediate host 
of the trematode Philopthalmus megalurus infecting the nictating 
membrane of a uatic birds. Another Oriental introduction, Melanoides 
puberculatus Muller, 1774), is an intermediate host for a Chinese 
uke. 
These are only a very few of the introduced species that are causin 
trouble -- sometimes by displacing native anbet an Perhaps tHe idee 
publicized was the case of Achatina fulica, the Giant African Snail 
in which it took three years of vigorous work to eliminate the off-— 
spring of three specimens brought in by a child to the Miami area.
