SOUTH AFRICAN MARINE MOLLUSKS. 163 



whorl decidedly angulated, marked by a broad spiral cord. Base 

 short, slightly rounded, marked by 14 somewhat flattened spiral 

 cords of somewhat irregular width, increasing slightly in width 

 from the periphery to the umbilical area. The spaces that separate 

 them are also of somewhat irregular width, but in general are almost 

 as wide as the cord. In addition to the spiral sculpture, the base is 

 marked by numerous coarse lines of growth which cut the cords but 

 do not render them tuberculated. Aperture subcircular; posterior 

 angle obtuse; outer lip thin; columella strongly curved and re- 

 flected over the base as a slight callus at the umbilical area. 



The type and two specimens, Cat. No. 249765, U.S.N.M., come 

 from Port Alfred (Coll. No. 1037). The type has a little more than 

 five postnuclear whorls, and measures: Altitude, 12.8 mm.; greater 

 diameter, 12 mm. 



Two additional lots are in the collection from Port Alfred, as fol- 

 lows: Cat. No. 187103, U.S.N.M., one specimen (Coll. No. 647); Cat. 

 No. 249764, U.S.N.M., two specimens (Coll. No. 1036). Another 

 specimen comes from Albany or Peddie, South Africa, Cat. No. 

 97988, U.S.N.M. 



This shell resembles in a general way C. eucosmia, but differs in 

 being much more narrowly conic, and also in detail of sculpture.
