Sjm. Adceon neaxesi p2tnctostnatus , Har. , 4th Ann., &c., 

 p. 121. 



Specific chai'acterization . — General form as indicated by the fig- 

 ure ; whorls about 5, the upper nearly or quite smooth, below 

 however there is a'subsutural spiral line while the greater part or 

 all of the body whorl is covered by spiral striae showing a tenden- 

 cy to alternate in size ; columellar fold strong ; substance of the 

 shell moderately thick. 



This species has much in common with lineatus Lea of the Clai- 

 borne sand, but is more nearl)'- related \.o piinctostriatus Ad., from 

 which it differs in thickness, position and size of columellar fold, 

 and height. A. cubensis is striated somewhat like this but it is 

 much shorter. 



Range in depth. — From 2,552 to 2,871 feet. 



Type. — Texas State Museum.

 No. 37, pi. 41, fig. 14. The Texan specimens are slightly more 

 globose, with a tendency to increase in size upwards instead of 

 downwards ; moreover its columellar plications are stronger than 

 those of bidentata.
