124 PROCEEDINGS OF THE ACADEMY OF 



Hepatns decoris. 



Dredged, and found on the beach. 



Hepatus angustatus, White ? 



Hippa talpoides, Say. 



Very common, in sheltered portions of the sandy shore, the 

 sand-bars, clear tide pools, &c. They often gather in large num- 

 bers in the pools among the stone jutties along the beach, actively 

 swimming about in a manner that forcibly recalls the similar 

 sports of the Notonectes, and burying themselves in the sand with 

 remarkable speed. Females with eggs were taken early in May. 



Eupagurus pollicaris, Stimp. 

 Eupagurus longipes, Stimp. 



These two hermits are found in every locality about the harbor, 

 except it be, perhaps, along the open beach, and in the muddiest 

 parts of the marsh. They were dredged in the deepest portions 

 of the channel, and are numerous in the tide-pools along the shore 

 and on the sand-bars. The smaller species is much the most 

 abundant, and finds ample accommodation in Nassa obsoleta, of 

 which there are thousands dead everywhere, Littorina, and shells 

 of similar shape ; the other is usually taken in young Busycons, 

 Fasciolarise, and the Cancellaria reticulata. 



Palaemon vulgaris, Say. 



C? Palsemonopsis carolinus.) 



Peneus braziliensis, Latr. 



The smaller shrimp I only noticed about the pools in the marsh, 

 "where it is extremely abundant. It is not, to my knowledge, used 

 in this locality, as the other fi-equently is. The latter occurs in 

 great numbers along the inner shores of the harbor and about 

 the sand-bars, and more sparingly in clearer parts of the marsh. 



Homarus americamis. 



One specimen was taken during the summer of 1870, the first I 

 ever heard of in this locality ; and it was a question whether it 

 had not been lost overboard from some vessel coming southward.
