While studying for systematic purposes the approximately 

 ninety species of bivalve molluscs which are found in the vicin- 

 ity of the Fisheries Laboratory at Beaufort, N. C, it seemed 

 desirable to consider which were available for scientific work 

 involving the use of living animals. A species represented at 

 the laboratory by a few specimens dredged in the deeper water 

 offshore, or by valves secured on the beaches, would be useless 

 for such research. Also species which might be abundant in 

 the vicinity but of which the habitat is not sufficiently well 

 known to permit of their being collected when wanted would be 

 equally useless. It is the purpose of this paper to indicate 

 which species are available in a living condition, specific local- 

 ities where they may be found, and when possible something 

 in reference to their abundance. A paper of this kind cannot 

 be complete, for further work will necessarily extend such infor- 

 mation. It can only include what is known at the time by the 

 writer. It is hoped that it may be of service to prospective 

 investigators by pointing out what material they would have 

 at their service under ordinary conditions. 



For the identification of the species and for assistance with 

 the literature I am very largely indebted to Doctors Dall and 

 Bartsch of the U. S. National Museum.
