This species is slill allied lo tlu; precedin^ onc, bul as ihc uiipcr pari of apcrtuie has 

 been broken and repaired diirinj,' life, it is iinpossible to j^mvc a sufficiL-iu descriplion, ihe 

 spiral sculpliire is nuuh finer iliaii in llu- prccedin^ species.

Slat. 193. Sanana-bay, East coast of Sula Hcsi. 22 M. Mud. i Spec. 



Shell cvlindrical, rounded al bolli emls, slij^dnly iruiualcd above, ralhcr soHd, opaque, 

 whittf. Sciilpture consistinjj of hair-like i^rowth-striae, a few ralher coarse, groovelike, spiral 

 striae above. and some more superficial ones below, these lalter occiipying a larger space 

 than ihe upper ones, about one third of the sheli is not spirally striatcd. Spire narrowly but 

 deeply umbilicated, ihe ui)])er pari of tlie umbilicus enamelled, bordered by an acute keel. 

 Aperture narrow above, larger below, its up|)er margin scarcely ascending, outer margin rounded 

 at first, then nearly straight, slightly conlracted, a little dilated below, basal margin regularly 

 rounded. 'Columellar side, along the body, convex at the ends, straight in the median part, 

 enamelled; columella scarcely concave, formed by a thick, scarcely contortcd fuld, covering the 

 umbilical slit. 



Alt. from margin of spire to base of apert. 5, lat. 2; apert. alt. 5'/,, lat. above '/,, 

 below I Mill. 



Same observation as for N" i: it is no agreeable task, lo describe new .species in such 

 a large genus, the danger of redescribing known species is not small, bul I have in vain tried 

 to identify them; from C. Javanica it is easily separableby its smooth median part. 



4. Cylichna sji. 



Stat. 139. 0° I r S., 127° 25' E. Near Katjan. 397 M. Mud. stones and coral. i Spec. 



This specimen is incomplete, part of the columellar side is wanling, so 1 have not 

 named il. though probably it will be new.

The brown zones are rather narrow and less deeply colourcd, but otherwise I see no 

 dififerences with the descriptions and figures, quoted above. 



6. Cylichna {Mnestia ?) sp. 



Stat. 105. 6°8N'., 121° 19' E. Sulu-archipelago. 275 M. Coralbottom. i Spec. 

 The only specimen seems to bc allied to the preceding .species, but it is a worn shell.
