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

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

 Notwithstanding these and other differences I do not doubt the 

 identity of the Bermuda example. 



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

 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 Keel's in 37 to 40 

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

 Bahia, Brazil (Miers). 



1 >n ul >t fnl Species. 



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

 parative Zoology, Cambridge, Mass., a -pecimen of Cancer borealis 

 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 Bay, Me., and ranging southward 

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



Boscia ?, sp. 



Willem.-Sllhm states that he collected a species in iicrmuda 

 "allied to JSoscia." No such species \\-as mentioned in the final 

 report by Miers. To what he refers is problematical. Jlnxi-iu is a 

 fresh-water genus {Pseudothelphusa). See Bibliography, below. 



Libinia emarginata Leach=L. <-<ni<i/i<-iiliii<t. 



This species is recorded by Hurdis (Rough Notes, p. ^<J1), without 

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

 identification was erroneous. It is common from Cape Cod to 

 Florida.
