or brownish epidermis. Sculpture consisting of more or less conspicuous growth-striae and more 

 or less close-set spiral rows of rounded punctures, which are especially conspicuous on the 

 ventral side, and, in most cases, much less so towards the aperture, where they have in many 

 instances the appearance of slightly punctured spiral striae; near the base the interstices have 

 nearly the character of lirae. Spire concave, concealed by an enamellous deposit, bordered 

 by an obtuse keel. Body-whorl not very convex. Aperture wide, especially in its lower part, which 

 is much dilated; its upper margin scarcely winged, elevated only a little above the body-whorl; 

 outer margin nearly straight, basal margin regularly rounded. Columellar side of body-whorl 

 not very convex above, covered by a thin layer of enamel, very concave below.

This species, by its shape and short wing, may be the nearest ally of S. cancellatus 

 v. Martens (Die beschalten Gastropoden der deutschen Tiefsee-Exped. 1898 — 99, p. 131, PI. 5, 

 fig. 19), but it is considerably more attenuated above, the body- whorl is much less convex 

 than in the figure of v. Martens, the sculpture seems to be different; however sculpture 

 scarcely seems to be a very constant character, as will be seen in the description of my new 

 species, the development of the punctures differing considerably in some parts of the shell ; 

 in some specimens very fine intermediate rows of punctures are perceptible, scarcely present 

 in other ones, the colour varies from yellow-brown to rather dark brown, even though being 

 quite fresh and containing the soft parts; however these differences can only be individual, 

 otherwise nearly every specimen should be a species. The same observations about sculpture 

 have been made in the preceding species. Likewise the different measurements have been made 

 after the same rule as in 5*. Sibogae.

Shell broadly oval, attenuated above, rather thin, white under a reddish-brown epidermis. 

 Sculpture consisting of folds, more crowded at the beginning of last whorl, more remote near 

 the aperture, and spiral rows of relatively large punctures, occupying a large part of the shell, 

 but less conspicuous towards the aperture and separated by narrow interstices, which are narrower 

 and more raised on the basal half, with true lirae near the base. Spire concave, concealed by 

 a deposit of enamel, bordered by a very low, rounded, white margin. Body-whorl rather convex. 

 Aperture wide, dilated below, upper margin with a small (broken) wing, outer margin regularly 

 but not strongly convex, basal margin regularly rounded, columellar side strongly convex along 

 the body, which is covered by an orange layer of enamel ; lower part or true columella 

 strongly concave.
