 i, p. 346, (figure), 1841 ; Ayres, op. cit., p. 143 ; Pourtales, op. cit., p. 13. Caudina 

 (Molpadia) arenata Verrill, Proc. Boston Soc. Nat. Hist., vol. x, p. 345, 1866. 



Vineyard Sound to Chelsea, Massachusetts. Sometimes abundant on 

 Chelsea Beach, after storms. Wood's Hole (H. E. Webster). Selenka 

 gives " Grand Manan " (? from specimens in Mus. Comp. Zool.), but 

 after very careful search during several excursions to that island, I have 

 never been able to find it there, and believe this to be an error. Stimp- 

 son knew it only from Massachusetts Bay.

New Jersey to Massachusetts Bay. Common in Long Island Sound, 

 at Savin Bock, and other localities near New Haven, in sand at low- 

 water ; abundant in Vineyard Sound, on Xaushon Island, etc. ; Cape 

 Cod; Chelsea Beach, Massachusetts. Sag Harbor, Long Island, 

 (Ayres). Selenka erroneously gives " Cape Florida" as the locality for 

 8. Girardii. It was based on Massachusetts specimens.

Body long, slender; integument translucent, filled with numerous 

 minute, scattered, opaque, light-red spots, oval or sub-circular in form ; 

 perforated plates smaller than in the preceding species ; anchors rela- 

 tively much longer, with a very slender, elongated shank. General
