396 A. E. Verrill — Decapod Crustacea of Bermuda. 



Stimpson did not notice the alternation of smaller and larger mar- 

 ginal teeth, but that condition was described by Miss Rathbnn. 

 Notwithstanding these and other differences I do not doubt the 

 identity of the Bermuda examjile. 



The only Bermuda specimen known to me was taken Sept. 30, 

 1905, at Long Bird Island (probably in a fish seine), by the expedi- 

 tion from the Field Natural History Museum. 



Stimpson's types were from off the Florida Reefs in 37 to 40 

 fathoms (Pourtales coll.). Porto Rico, four stations (Rathbun). 

 Bahia, Brazil (Miers). 



Doubtful Species. 



According to M. Walter Faxon there is in the Museum of Com- 

 pai'ative Zoology, Cambridge, Mass., a specimen of Cancer horealis 

 Stimpson, labelled as from Bermuda. 



My belief is that its label is erroneous, or has been accidentally 

 transposed. It is a large northern species, common at low tide on 

 some of the rocky shores of Casco Ba^^, Me., and ranging southward 

 in the deeper water of the arctic current as far as off Cape Hatteras. 



Boscia ?, sp. 



Willem.-Suhm states that he collected a species in Bermuda 

 "allied to Boscia.''^ No such species was mentioned in the final 

 report by Miers. To what he refers is problematical. J3oscia is a 

 fresh-water genus { — Pseudothelp/iusa). See Bibliography, below. 



Liibinia emarginata Leach^^L. eanaliculata. 



This species is recorded by Hurdis (Rough Notes, p. 361), without 

 any notes. It has not been found by anyone else. Probabh^ his 

 identification was erroneous. It is common from Cape Cod to 

 Florida.
