Family CONIDAE 

 Genus Conus Linne 1758 



Conus spurius atlanticus Clench Alphabet Cone 



Plate 14P 



Florida and the Gulf of Mexico. 



2 to 3 inches in length; spire slightly elevated in the center. Top of 

 whorls smooth, except for tiny growth lines. Color white with spiral rows 

 of orange-yellow squares. Interior of aperture white. A rather common and 

 attractive species found in shallow water. True spurius spurius Gmelin from 

 the Bahamas and Antilles differs only in having the spots merging into occa-

 sometimes smaller and a rather dark bluish purple.

Tortugas to off Yucatan, Mexico.

 more slender. Characterized by several spiral bands of light-yellow. Dredged 

 in several fathoms of water. Uncommon to rare. It is possible that this spe- 

 cies may be only a freak color form of spurius.
