Epelys montosus Harger, Eep. U. S. Fish Com., part i, p. 571 (277), 187i.—Idotca 

 monlosa Stiiupsou, Mar. Invert. Grand Manan, p. 40, 1853. 

 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=-Leac7(ia (jramdata G. 0. Sars, Arch. Math, og Naturvid. 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 description appears 



to apply perfectly to the specimens described by myself before seeing 



his paper. 



Sphaeroma quadridentatum Say, Jonr. Acad. Nat. Sci. Phil., vol. i, p. 400, 1818. 



A southern species, scarcely passing north of Cape Cod, but occurring

 Leach, Edinburgh Encyc, voL vii, p. "433, 1813-14"; Trans. Liuu. Soc. Lon- 

 don, vol. xi, p. 371, 1815. 

 This genus was associated with the Asellidce 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 liave placed it in a 

 family by itself, the Limnoriida\ 



The species extends throughout the New England coast.
