Eusarsiella americana (Cushman).—Poulsen, 1965:83 [in key].

LECTOTYPE.—USNM 113357, male designated by Kornicker (1967).

TYPE-LOCALITY.—Cushman (1906:366) reported collecting specimens used in describing the species from a channel across from Woods Hole Harbor, known locally as the “Gulf of Canso.” Fish (1925: 141) referred to that locality as the “Gut of Canso.” On the United States Coast and Geodetic Survey map of Woods Hole (no. 348; reissued 1917) the locality is designated “Gate of Canso.”

MATERIAL.—From the Cape Cod Bay quadrat area, 251 specimens (the number of specimens at each station is listed in Table 1); 1 male from a water depth of about 10 cm at low tide at Grays Beach, Kingston, Massachusetts, and 2 specimens from a water depth of about 10 cm at low tide at the inlet to Jones River, Kingston, Massachusetts.

An example of an American species being introduced into European waters probably in association with oysters. It was first recorded by L.S.Kornicker.
