This shell differs from the Cucullaa concamerata, Martini (Cucul- 

 Icea auriculifera, Lam.), as follows: 1. It is thinner and less trans- 

 versally prolonged ; 2, the elevated longitudinal striae are not flat, 

 and not broader than the interstices, as with the other species, ap- 

 pearing subtilely granulated by transversely crossing and very close 

 striae ; 3, the ligamentary area is somewhat flatter ; 4, the internal 

 auricles are smaller ; and 5, there are on the anterior side three and 

 on the posterior four lateral teeth, whilst the other species has on 

 each side one tooth less. {Car dine utrinque subbicostato, Lam.)

The umbones are situated so near the anterior end that the su- 

 perior margin of the shell almost forms the area.
