A REVIEW OF THE VOLUTIDAE 



po3t-nuclear whorls, two and one-half; su- 

 ture distinct; surface covered with strong, 

 longitudinal growth lines; outer lip thin, 

 china-like, extending upon the penultimate 

 whorl almost to suture; columella oblique, 

 with three, feeble plaits; heavy posterior 

 wall callus; ground color brownish gray, 

 overlaid with a sparse pattern of tan, form- 

 ing designs resembling pyramids and arrows; 

 nucleus, colored a dirty yellow; the aper- 

 ture, whitish yellow; a broad zone of this 

 color extends upon surface of body whorl; 

 columella milky orange. 



The nucleus of this shell was re- 

 ported thus by Reeve in his Conchologia 

 Iconica: "This shell is in a very immature 

 state, and there can be little doubt of the 

 swollen apex being a malformation. "
