in Reeve. Conch. Icon., pi. 1, fig. 1. Brazier, Proc. Linn. Soc,

This species is only represented by the dorsal surface showing 

 two transverse bands. Mr. Sowerby figux'es it in the Thes. Conch, 

 figure 59, as Bulla a7)ipulla, Linn., but in Reeve's Conch. Icon., 

 he re-describes it as Bioda tri/asciata. I believe it to be only a 

 variety of an^ndla.
