Small examples, some of them built up of exceedingly coarse sand-grains, occur in 

 the three deeper soundings. 



Figure 16 may perhaps be assigned to the present or the last-named species ; whilst the 

 somewhat broken, rough, thick-shelled specimens, figs. 11, 12, and 15, probably belong 

 to the spiral section of the Lituoline group, though too obscure for identification.
