ON A COLLECTION OF CRUSTACEA FROM VIRGINIA, NORTH CAROLINA, 

 AND FLORIDA, WITH A REVISION OF THE GENERA OF CRANGONIDJE 

 AND PAL-EMONIDJE. 



BY J. S. KINGSLEY. 



The specimens enumerated below were collected, with a few 

 exceptions, by Prof. H. E. Webster, of Union College, at North- 

 ampton County, Virginia (eastern shore, Atlantic side), beach of 

 Chesapeake Bay, opposite Fort Monroe, Ta., in the vicinity of 

 Beaufort, N. C, and Marcou Pass, Florida Bay, Harbor Key, 

 Plantation Ke} r , and Key West, Southern Florida, and Oyster 

 Bay, Charlotte Harbor, Sarasota Bay and Little Sarasota Bay, 

 on the west coast of Florida. I have endeavored to indicate to 

 a certain extent the geographical distribution of the species by 

 giving, in most instances, a list of localities from which specimens 

 have been reported, with the authority for the statement. In cases 

 where I have personally examined specimens, I have placed an 

 exclamation mark (!) after the locality followed by the name of 

 the collector. The arrangement followed in the Maioidea is that 

 of Miers (Jour. Linn. Soc'y, xiv. pp. 634-673, 1879). In the re- 

 maining gi'oups of the Brachyura, mainly that of Dana, the Ano- 

 mura, according to Stimpson (Proc. Acad. Nat. Sci. Philadelphia, 

 1858, pp. 225-238), while the order of the Macrura is essentially 

 that of Dana. A short notice of some of the new forms will be 

 found in the American Naturalist, vol. xiii. p. 584, September, 

 1879.
