Of this species, which is reported from Rio Janeiro by Edwards 

 and Dana, and from Cuba by von Martens, two specimens were 

 collected by Prof. Webster, one at Sarasota Bay and the other at 

 Charlotte Harbor. 



Genus Peneus Fabr. 



Peneus constrictus Stm. A single specimen was collected at 

 Marcou Pass. 



Peneus braziliensis Latreille. From Beaufort, N. C, Marcou 

 Pass, Charlotte Harbor, and Sarasota Bay, Fla. I would here 

 say that the specimens described by me as Peneus brevirostris 

 (Proc. Acad. Nat. Sci. Philadelphia, 1878), from the west coast of 

 Nicaragua, prove to be P. braziliensis, thus adding another to 

 the list of species common to both coasts. 



In my " List of Decapod Crustacea of the Atlantic Coast, 

 whose range embraces Fort Macon" (Proceedings Philadelphia 

 Academy, 1878, pp. 316-330), I enumerated sixty-five species, of 

 which fiftj'-three had at that time been reported from Fort Macon. 

 In this paper six more of these species are reported from there, 

 while Poly onyx macrocheles, Lepidops venusta, Hippolysmata 

 wurdemanni, and Concordia gibberosa, which were not enumerated 

 in my list, were found there by Prof. Webster, and Ogyris alphx- 

 rosh'is, from its near locality, may reasonably be expected there.
