CONIDAE 179 



obtuse, with a single spiral thread and above this a flattened ridge; 

 shoulder rounded, sutures slightly canaliculate, edged along the 

 upper margin of each whorl by a narrow band of brown; ground 

 color bluish gray with closely placed revolving chestnut-colored stri- 

 ations, faint near the shoulder, stronger over expanded portion of 

 body whorl, becoming elevated threads over narrowed basal por- 

 tion; aperture oblique, narrowed above, regularly increasing in width 

 to base of shell; outer lip thin, sharp; chestnut stam well within 

 aperture; growth lines exceedingly fine and numerous; periostracum 

 thin and pale brown; operculum thin and small for the relative size 

 of the aperture.* 



Conus sozoni"-" Bartsch PI. 55, fig. 363 



Alt., 17 to 100 mm.; max. width, 42 to 47.5 mm. Color white, 

 with three pinkish brown bands; entire shell encircled with brown 

 spots, which seem darker and more profuse on the bands. On the 

 spire the brown markings are heavier and axially curved. About 

 12 or 13 whorls, spire concavely elevated, sutures distinct, each whorl 

 strongly keeled. Body whorl is smooth, with 8 to 10 spiral ridges 

 toward the base. Most adult shells have had the lip broken and are 

 roughly mended, giving the shell a battle-worn appearance, though 

 the pattern of bands and dots is fairly continuous. Aperture oblique, 

 narrow; the outer lip thin and delicate, convexly curved forward; 

 small, corneous operculum.* 



Beach specimens of C. citrinus and C. verrucosus have been 

 found on the Gulf beaches of western Florida, but there seems little 

 evidence for a local station. 



Conus floridanus Gabb PI. 37, fig. 255 



Alt., to 50 mm. Shell with general characters of C. spurius. 

 About 12 whorls, spire acute, well elevated, ascent of whorls ter- 

 raced; mottled and obscurely banded in yellow and white, scattered 

 brown spots; epidermis thin, brownish.
