_ Near the preceding, but of smaller size, thinner, the suture not white, but of the 
same pale yellow colour as the rest of the shell. Owing to the kindness of M. A. 
Morelet, I have been enabled to compare directly his original specimens of S. meridana 
(fig. 25) with the type of S. cobanensis, Tristr. (fig. 26), and with the figure of Fischer 
and Crosse’s S. cornea; Morelet’s type is only a little smaller, comparatively more slender, 
and paler in colour, without any marked difference. The statement “length 18 millim.” * 
is a misprint for 13 millim., as shown by the specimens themselves.
