appears to be constant ; the latter is more fusiform, and has a 

 narrower aperture ; its spire is longer in proportion to the body- 

 whorl, and generally more or less plicated ; while all the 

 numerous specimens of A^. analogica I have before me are 

 smooth, excepting for the spiral grooves. These differences 

 may appear to be merely varietal, but the comparison of a large 

 number of specunens shows that they are singularly persistent, 

 and the two forms when separated show very little variation. 



Cancellaria PRODUCTA (Plate IV., fig. 5). Shell elongately 

 acuminated, very pale buff colour. Spire narrowly pyramidal ; 

 whorls 7^, the first 2\ rounded, smooth, shining, regular, the rest 

 convex, latticed by numerous spiral lirae, and longitudinal ribs ; 

 the spirals (6 or 7 on the penultimate whorl) form little nodules 

 in crossing the ribs, some of which are spinously raised in prox- 

 imity to the suture ; suture rather deepiy channelled. Last 

 whorl a httle longer than the spire, closeiy cancellated through- 

 out. Aperture sub-ovate, rather small ; columella nearly 

 straight, with 3 oblique nearly equal plic^ ; outer lips sharp at 

 the edge, and slightly thickened by the external rib. 



Length 17; width 7 millim. 



Hab. :— Off L^mhloti River Mouth (Natal) ; depth, 40 fathoms 

 (two specimens only). 



This shell resembles in form some of the species of the genus 

 Phos. 



Epidromus CREBRILIRATUS (Plate IV., fig. 4). Shell nar- 

 rowly oblong, fulvous, faintly banded and variegated with brown, 

 pearly white at the apex. Spire elongately acuminated, slightly 

 convex at the sides; whorls 5^, the first i^ smooth and shining, 

 the rest rather convex, irregularly plicate and varicose ; spirally 

 finely grooved ; suture scarcely impressed. Last whorl oblong, 

 rather straight sided, with a very short rostrum at the base. 

 Aperture rather wide in the middle, and narrow at each end ; 

 columella covered with a thin white callus standing erect over the 

 umbilical region, sliglitly and irregularly pustulate ; canal short, 

 narrow, slightly recurved. 



Length 13 ; width 5 millim. 



Hab. : — Glendower Beacon (near Port Alfred) bearing N. \ 

 \V. ; distant 21 miles; depth, 100 fathoms. Bottom, sand and 

 stone. (Two specimens only.) 



Somewhat resembling a small form of E. lanccolatus, Menke, 

 but quite different in sculpture. 



Scala TENEBROSA (Plate IV., fig. 6). Shell elongately tur- 

 reted, dark brown, with ribs of a somewhat lighter colour. Spire
