LIST OF SHELLS COLLECTED BY DR. JOHN I. 



NORTHROP IN THE BAHAMAS, IDENTIFIED 



BY PROFESSOR WILLIAM HEALEY DALL, 



SMITHSONIAN INSTITUTION 



The following list was made from Dr. Northrop's specimens which 

 were sent to the National Museum for the purpose. So many shells 

 have been collected at the Bahamas during the last two hundred years 

 that the fauna is fairly well known, and it was not to be expected that 

 any very remarkable additions to it could be made on such a collect- 

 ing trip. Well- identified species, however, always have a certain value 

 for science, in their bearing on geographical distribution, as the locali- 

 ties given by the earlier collectors were often vague or inaccurate. 



That Cyrena floridana and Macroceramus pontificus should occur 

 was interesting, and a number of the other species, though known to 

 belong to the general region, had not heretofore been specifically 

 located in the Bahamas. 



The shell identified as Mitra flammea is bleached and worn, and 

 may be another species. It is not, however, any of those commonly 

 known as Antillean.
