This little shell may be a dwarf specimen of the Atlantic 

 species (as the authorities have decided ; in which case it is 

 difficult to say how it got into the box of C. arabicula ;) or it 

 may be an allied Pacific form. It has rounded pits along the 

 labral side, and a few at the top and bottom of the labial. One 

 turn of the spire is seen. Colour resembling C. stercoraria on 

 the back ; orange brown at the sides ; light brownish yellow 

 in front. Long. '84, lat. '5, alt. '39.
