Preliminary Report on Mollusca. 7 



by numerous longitudinal striæ; on the top-whorls only ap- 

 pears a regular reticulation; Apex regular, depressed, smooth 

 and glossy. 



Size: L 15, 5 B. 7- 5 mouth incl. canal 9 mm . 



Hab: St. 51, 1120 f and „Porcupine" Expdn. St. 64, 640 fand 

 (35,345 f- (Dr. Jeffreys). 



The above described specimen is a young one, and was the 

 only one met with in the Norwegian Expdn., but at Dr. Jefireys's I 

 have seen some exceeding double the size,from the„Porcupine" Expdn. 



Radula has upwards of 90 joints and the teeth are of a 

 peculiar simple form. Fig. 14.

Form fusiform ; whorls 7, somewhat convex ; the last extending 

 about three — fourths of the length; suture not very deep, mouth 

 piriform, pointed above; columelle varies in four specimens from 

 being almost straight, to being strongly bent; canal somewhat long, 

 outer lip sharp and faintly sinuous, inner lip forming a not very 

 broad, and very thin enamel on the pillar. Shell rather thin, white 

 with a cortical hairy epidermis; structure consists of more or less 

 strong spiral-ribs and numerous fine lines of growth. 



Size : L. 54. B, 25 mouth incl. canal 32. 



Operculum earshaped Fig. 15a. 



Radula has about 90 joints; Fig. 15 the teeth. 



Hab: St. 33,510 f. Three living specimens all enclosed by 

 an Actinia which had eroded the top- whorl. 



Some yellow transparent egg- capsula 7 mm large, of a roundish 

 form, having a broad basis attached to the tube of a S ab el la, I 

 would refer to the above species. The capsule contained only 

 one embryo, and in one instant this no doubt within short time 

 would imerge from its confinement, as a comparatively large, round 

 mark on the one side of the capsule, was very worn and trans- 

 parent so the movement of the animal was visible within. 



On examining Radula I found the lateral teeth most developed 

 but not yet become constant; one having 3 spines, another with 

 the same number, but with the central spine double, and a third 

 having 4. The spines of the central-plate are not yet developed, 

 but there is an indication of 3. Fig. 16. 



Operculum is exceedingly thin, oval; lines of growth only 

 tolerably regular along the upper border, otherwise, they are bro- 

 ken by faint curved folds, radiating from the nucleus, Fig. 16%
