By W. L. MAY. 3 3^ 



Locality: Type from 100 fathoms seven miles east of 

 Cape Pillar, with a number of others. A shell of simple 

 character, very constant in form and colour in the type 

 locality: but some examples taken in 15 fathoms in 

 Geography Strait vary from typical, to others which are a 

 uniform rich brown, and somewhat broader and heavier. 

 In South Australia it varies considerably in size, and 

 sometimes loses the colour bands also. 



Named in honour of Air. C. J. Gabriel, an enthusiastic 

 conchological worker.

 Australia (Dr. Verco).
