NOTES ON THE NATUEAL HISTORY OF FORT MACON, N. C, AND 



VICINITY. (No. 2.) 



BY ELLIOTT COUES. 



As the identification of the Fishes and Insects that were col- 

 lected seems likely to be delayed, our "Notes" are continued^ with 

 lists of the Crustacea Decapoda, and of the Shells, mostly marine, 

 as well as of a few other marine Invertebrates. 



CRUSTACEA DECAPODA. 



The identifications of most of the species were made by Prof. 

 S. I. Smith, of the remainder by Dr. Wm. Stimpson. The ma- 

 jorit}' of tlie specimens referred to, including all those taken with 

 the dredge alone, were collected by Dr. A. S. Packard and myself. 



Libinia canaliculata. 



Dredged in various parts of the harbor, and found common 

 on Bird Shoals. ( Cf. Streets, these Proceedings, 1810, pp. 104-5.) 



Cancer irroratus, Say. 

 Beach and elsewhere. 



Menippe mercenaria. " Stone Crab." 



Common, and highly esteemed as an article of food. It is much 

 less generally distributed than, not so abundant as, the common 

 edible crab. 



Panopaeus berbstii, Edw. 



Panopaeus berbstii var. obesus. 

 Pilumnus aculeatus. 



A few specimens, dead on the beach.

 middle of April.
