Eeplaces the preceding species for the most part at the north, but 

 found also as far soutli as Long Island Sound. It has been obtained 

 from a depth of 40 fathoms. 



Astacilla granulata = Leach ia grannlatn G. O. Sars, Arch. Math, og Natnrvid. Chris-

 Am. Jour. Sci., Ill, vol. xv, p. 374, 1878. 



St. George's Banks, 1877, and Banquereau, 1878. I have seen no 

 specimens of Sars's species for comparison, but his descri])tion ai)pears 

 to apply perfectly to the specimens described by myself before seeing 

 his paper. 



Spheeroma quadiidentatiim Say, Jonr. Acad. Nat. Sci. Phil., vol. i, p. 400, 1818.

This genus was associated with the AseUidct' by Edwards without an 

 examination of the specimens, and, so far as I know, he has been followed 

 by recent authors. An examination of its structure appears to point 

 unmistakably to affinity with the Sphccromidce. I have not, however, 

 thought best to include it in that family, but have placed it in a 

 family by itself, the Limnoriidcc. 



The species extends throughout the Kew England coast.
