torn of the same character. Four other specimens (/'), two males 

 and two females, one of which was carrying eggs, were dredged near 

 these localities, August 31, 1878, latitude 42° 33', longitude 69° 35', 

 in 100 to 115 fathoms, mud and stones. Fragments of a large speci- 

 men were also found in the stomach of a cod-fish taken in ninety-eight 

 fathoms, soft mud, fourteen miles southeast of Cape Ann, September 

 2, 1878. 



The G. tridens was described by Kroyer (Naturhistoi*isk Tidsskrift, 

 i, p. 10, pi. 1, 1836) from specimens taken on the coast of Denmark. 

 It has since been reported from Christiania Fiord, in ten to twenty 

 fathoms (G. O. Sars, Christiana Videnskabs-Selskabs Forhandlinger 

 for 1873, p. 393) and a few other Scandinavian localities, and from 

 off Velentia, Ireland, in 159 fathoms (Thomson, " Depths of the Sea," 

 p. 87, fig. 9, 1873). Like its American representative, it seems to be 

 a deep-water species rarely taken in the dredge. 



Panopeus depressus Smith. 



Provincetown ! (1872), Massachusetts, to the Gulf of Mexico! 

 (Col. E. Jewett, et al.). This and the next species are apparently 

 regular inhabitants of Cape Cod Bay. They are both, but more 

 particularly this species, very abundant upon oyster-beds everywhej-e 

 south of Cape Cod and are often carried alive long distances amono- 

 oysters, so that it is diificult to determine their exact northern range. 



Panopeus Sayi Smith. 



Provincetown ! (1872), Massachusetts, to the Gulf of Mexico! (Col. 

 E. Jewett). Apparently less abundant, at least on the New England 

 coast, than the last. 



Panopeus Harrisii Stimpson ex Gould. 



Massachusetts Bay! (Coll. Boston Soc. Nat. Hist.) and Long Island 

 Sound ! to St. John's River, Florida ! (G. Brown Goode). This 

 species, originally described by Gould, from Charles River, Massa- 

 chusetts, is apparently a thoroughly brackish-water form. The 

 specimens from the St. John's River, as 1 am informed by Mr. 

 Goode, were taken at Arlington Bluffs, twenty-two miles from the 

 mouth. It was associated at this place with Sesarma cineria, Palce- 

 raonetes vulgaris, and a JBopyrus which infested the branchial cavity 

 of nearly every specimen of the latter species. Mr. Goode Avrites 

 that these species were taken in water perfectly fresh to the taste, 

 though brackish water is sometimes driven by the wind up the river 

 to where they occurred.
