S. SIGNUM, Reeve. PI. 5'5, fig. 370. 



Yellowish, marbled with gray or light brown, with five or six 



narrow brown revolving bands. Length, 2 inches. 



S. Japan. 



Very like S. Cassidarineformis in shape, but smooth, and more 

 produced and contorted inferiorly. 



S. concinna, A. Adams, may be synonymous, as suggested by 

 Kobelt.

Light brown, ridges profusely stained with small spots of 



deeper color. Length, 46 mill.

 somewhat narrower ; the canal also, is a little more produced.

Whitish fawn, sparingly streaked longitudinally with brown, 

 and ornamented with sub-equidistant revolving dark brown lines. 



Length, 1*6 inches. 



Corea, 70 fathoms. 



I have not seen this species ; the figure of it appears very 

 closely related to the preceding, and it is probably .synonymous 

 with it.

chocolate within the aperture. Length, 40 mill.

The very short canal and smooth surface as well as the peculiar 

 color-markings almost suggest Eburna rather than Siphonalia.

 Yellowish white, more or less stained with rust-red.
