 Little Gull Island. 



Our labors extend over a period of more than eleven years, 

 and during that time we have dredged several seasons in Pe- 

 conic and Gardiner's Bays and at Huntington. We regret 

 that circumstances have prevented us from exploring with 

 the dredge the ocean shores of the island ; we have, however, 

 examined nearly all the beaches. Our researches for land and 

 fresh-water shells have been carried on through nearly the whole 

 island. 



We would call attention to the fact of the discovery of a 

 species of Gundlachia, a genus which, up to the present time, 

 has not been found north of the District of Columbia. With 

 regard to two species, Astarte lunidata and t 'orbula contracta, 

 as will be seen in the enumeration, we have not been able to 

 discover any evidence of their being found in the living state 

 north of Cape Ilatteras, though such seems to have been tacitly 

 assumed to be the case. In connection with this subject we 

 will mention the discovery on our ocean coasts, in the dead 

 state, of Area ponderosa of the South. 



It would have been very desirable to have instituted a thor-
