A pure white shining species, of nearly the same form as 

 G. hijjlicata^ A. Ad., but rather narrower, with the columella 

 only spirally twisted, and the transverse stride finer.

Hob. ? 



This species may be at once recognized by the lacteous 

 bands upon a hyaline ground, and by the peculiar subtrunca- 

 tion of the columella, which almost forms a short channel with 

 the outer lip.

C. testa minutissima, breviter cylindracea, aliquanto medio contracta, 

 superne quadrata, alba, longitudinaliter curvatim lirata ; vertex 

 umbilicatus, margine rotundato ; apertura superne angusta, ad 

 basim perdilatata ; columella spiraliter torta.

Hah. Persian Gulf [Col. Felly). 



This species was dredged by Col. Pelly in great numbers 

 at a depth of 14 fathoms. It is remarkable for its minuteness, 

 the longitudinal curved ridges, and the very dilated aperture 

 towards the base.

C. testa minutissima, elongato-cyhndracea, alba, longitudinaliter 

 curvatim striata ; vertex umbilicatus, carina acuta circumcinctus ; 

 apertiu-a superne angusta, inferne modice dilatata ; labrum pau- 

 lulum medio contractum ; columella spiraliter torta.
