 southeastern Gulf of Mexico, off the Yucatan 

 Peninsula, it was reported from 37 m (Springer 

 and Bullis, 1956) to 78 m (Rice and Kornicker, 

 1965) . In the northern Gulf, this species is com- 

 mon in depths of 32 to 65 m (Parker, 1960); 

 and in the northeastern Gulf, it was reported 

 from 11 to 93 m (Carpenter, 1967) . In the east- 

 ern Gulf, calico scallops were found in depths 

 from 6 m (Bullis and Thompson, 1965) to 46 m 

 (Bullis and Ingle, 1959). Off the Florida east 

 coast, the calico scallop was reported from 9 to 

 74 m by Drummond (1969) , although maximum

 (Cummins) ." Off North Carolina, south of Cape 

 Hatteras, calico scallops were found from about 

 13 m (Bullis and Thompson, 1965) to at least 

 94 m (Cummins, Rivers, and Struhsaker, 1962). 

 At the northern end of its range, north of Cape 

 Hatteras, reported depths of occurrence range 

 from 33 to 44 m (Merrill, see footnote 4). At 

 Bermuda, the calico scallop occurs in less than 

 2 m of water (Kirby-Smith, see footnote 3) . 



The calico scallop inhabits open marine water 

 and does not usually occur in estuarine areas as 

 do the nucleus scallop and the Atlantic bay
