directed towards the front-side, apparently slightly incised in the centre (this is not certain, the 

 margin not being quite intact) ; a thin slitcallus seems to exist. 



Long. 6, lat. 5, alt. 3 1 /,, Mill. 



This interesting species will be easily distinguished by its beaded sculpture, I find in 

 litterature only P. agger Wats. (Challenger Gastrop. p. 40, PI. 4, fig. 6) which has a similar, 

 but still different sculpture, and may be distinguished by its shape, slit, septum, etc. 



1. Piincturella (Cranopsis) gigantea n. sp. PI. VII, hg. 4. 



Stat. 122. i°58'.5N., i25°o'.5 E. 1165 — 1264 M. Stone. 1 Spec. 



Shell depressed, conical, base oval, apex curved. Front slope convex, posterior and lateral 

 slopes concave, the apex shows about one volution at its right side, placed at nearly 2 /., of the 

 total length. Sculpture consisting of close-set, radiating riblets, which are alternately stronger and 

 are crossed by concentric ridges, which make the riblets crenulated, the weaker riblets come 

 near to, but don't reach the summit. Slit-fasciole rather deep, long about 7 Mill. crossed by 

 thin lamellae, orifice about 4 Mill. in length, perhaps largest above (or slightly broken) ending 

 in a blunt point, at J S L Mill. from the front margin. Interior white, with shallow, radiating 

 grooves, corresponding to the exterior riblets, and making the thin margin crenulated ; from the 

 summit runs the septum, closing the upper part of the slit-fasciole, thickened at the sides of 

 the fasciole and along the orifice, below this follows a rather strong, interior rib. 



Long 29, lat. 2 2 1 /,, alt. 1 2 1 /, Mill. 



Allied to P. (Cranopsis) aethiopica v. Martens (Die beschalten Gastropoden der deutschen 

 Tiefsee-Exp. 1898 — 99, p. 128, PI. 5, fig. 9) but much larger, more elongated, with (according 

 to the figure) much finer sculpture, the apex more terminal; the slit is more regular and sym- 

 metrical, I think however this last character has not much value, as it may bè individual, like 

 v. Martens suggested. 



Rimula Defrance. 



1. Rimula carinifera n. sp. PI. VII, fig. 5. 



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



Shell depressed, conical, with curved apex, base oval. Front slope very convex, side 

 slopes moderately convex, posterior slope slightly concave, apex with about one volution, visible 

 at the right side; it is placed at about 9 / u of the total length. Colour white. Sculpture consisting 

 of rather strong radiating ribs and a few intermediate ones, and weaker concentric ridges, 

 making the ribs crenulated and leaving in the interstices subquadrate pits. Perforation oblong, 

 oval, long s / 4 , broad l j. i Mill. Slit-fasciole just above the perforation shallow, higher 11 p the 

 shell prominent, so as to make it carinated; the fasciole crossed by rather thin, slightly curved 

 lamellae, which towards the perforation are transformed in scales. Interior white, smooth, but 

 having the appearance, by the transparency of the shell, of being grooved ; margin crenulated, 

 slightly elevated at the sides, apex deeply pitted.
