5. Emarginula sublaevis n. sp. PI. VII, fig. 9. 



Stat. 280. 8°i7'.4S., 127 t,o'.j E. 1224 M. Probably hard bottom. 1 Spec. 



Shell oval, moderately depressecl, front and side slopes convex, posterior slope concave 

 in the upper part, slightly convex below. Colour yellowish-white, with a row of small, brown 

 spots at each side of the slit and fasciole. Apex placed posteriorly, at about n / ls of the total 

 length, with a whorl on the right side. Sculpture consisting of rather numerous, thin, radiating 

 riblets, about 33 on each side, which are alternately stronger, with broader interstices, with 

 commonly 3 smaller intermediate riblets. This radiating sculpture is crossed by numerous con- 

 centric ridges, giving to the shell the appearance of being covered by elongate granules. Slit- 

 fasciole narrow, laying deep, by the strongly elevated margins, sculptured by rather remote 

 arched lamellae and intermediate striae. Slit long about 3, large nearly 1 / 2 Mill., its margin 

 thickened interiorly, a rather shallow groove, deep near the slit, with a rather strong rib at 

 each side, runs towards the apex. Interior slightly grooved, white in the centre, yellowish towards 

 the slightly crenulated margin, which is a little raised at the sides. 



Long. 13, lat. 9 1 /.,, alt. 7 Mill. — — 



I know 110 species to which this one is closely allied, its weak though very beautiful 

 sculpture is very peculiar. 



6. Emarginula dubia n. sp. PI. VII, fig. 10. 



Stat. 95. 5°43'.5 N., U9°4o'E. 522 M. Stony bottom. 1 Spec. 



Shell oval, sub-depressed, yellowish-white, front slope very, side slopes slightly convex, 

 posterior slope slightly concave, much so below the apex, which is placed at about 6 / 7 of the 

 total length, and has a whorl on the right side. Sculpture consisting of numerous radiating riblets 

 about 116 in number, with a smaller one in the majority of the interstices; they are crossed 

 by thin concentric ridges, forming beads on the riblets. Slit-fasciole rather deep, with numerous 

 lamellae crossing it. Slit long 2, large l / s Mill., its margins thickened interiorly, a flattened rib 

 runs towards the apex. Interior smooth, yellowish, margin crenulated, with slightly raised sides. 



Long. 7, lat. 5 1 /,, alt. 3^ Mill. 



Resembling the figure of E. bcllula Adams, in Pilsbrv's monograph (Man. of Conch. 

 Vol. XII, PI. 28, fig. 37) but the apex is placed more central, the slit-fasciole is not punctured 

 etc. I am however not quite certain, that this species of simple characters has not been 

 described, but have failed, even with the assistance of Mr. E. A. Smith, to identify it with any 

 known species. 



7. Emargimila foveolata n. sp. PI. VII, fig. 11. 



Stat. 105. 6°8'N., 121 19' E. 275 M. Coralbottom. 1 Spec. 



Shell oval, broader behind, conical, colour grey (probably not the natural colour), front 

 slope strongly, side slopes slightly convex, posterior slope concave, apex curved, placed at about 

 3 /., of the total length, the apex being slightly worn, 110 whorl is visible. Sculpture consisting
