200 BIOLOGICAL SURVEY OF 



by Woods Hole Survey. Reported from Eastport, Casco Bay, 

 from fish off Cape Ann, Grand Manan, Halifax fishing banks, 

 Halifax Harbor, Gaspe Bay, Little Metis, and Kamonraska. 



Calyptraeidae 

 Crucibulum Schumacher 

 C. STRIATUM (Say). {Calyptraea triata Say, 1826, Jour. 

 Nat. Acad. Sci. Phila.; C. striatum, Gould, 1870, Inv. Mass., 

 p. 275, fig. 536.) A common form on rocky bottom. The 

 'cup and saucer' limpet. One 23 mm. in diameter taken. Sta- 

 tions: D39, 62-64, 83, 87, 119, 142, 144. Reported from 

 Eastport to off New London, Grand Manan, Bay of Fundy, 

 to 30 fathoms ; Charlotte Co., N. B., very abundant ; Annapolis 

 Basin, not abundant. 



Crepidula Lamarck 



C. fornicata (Linne). (Patella fornicata Linne, 1767, Syst. 

 Nat.; C. fornicata Gould, 1870, Inv. Mass., p. 271, fig. 532.) 

 One large specimen dredged at station D 63, and some very 

 large specimens taken at spring tides, S 44, with shells very 

 thin. This is the 'boat shell.' Common from Casco Bay to 

 Connecticut. Reported abundant throughout entire Canadian 

 region on oysters, northward to Caraquette Bay. 



C. glauca Say. (Say, 1822, Jour. Acad. Nat. Sci. Phila.; 

 Gould, 1870, Inv. Mass., p. 274, fig. 535.) But two individuals 

 dredged and both at station D 43. Woods Hole Survey re- 

 ports it as C. convexa, while Johnson, in the Fauna of New 

 England, Boston Soc. Nat. Hist., lists it is C. glauca convexa, 

 "a form due to growing on the shells of Alectrion ohsoleta 

 and other convex surfaces." "C. glauca Say, which was 

 included by Willis in his latest list of Nova Scotian shells, 

 was regarded by Dr. Stimpson as a synonym of C. fornicata." 

 (Whiteaves).
