The straw-coloured thin cuticle or periostracum surrounding the 

 \\hite surface is thick with chestnut-coloured spiral lines. In this 

 respect, judging by Mr, Pilsbry's figure (Man, Conch, xv. pi. 50, 

 f. 38), it resembles T. culcitella Gould, from California. The 

 whorls are profoundly, but narrowly channelled, form straight and 

 cylindrical, columella strongly once-plaited, A good many 

 examples were dredged in December 1900, at the above-named 

 locality,
