(Plate xlvii., fig. 72.) 



Shell rather tliiu aud light, biconical, tiirreted, and sharply angled 

 at the shoalder. Colour baff, with riifous .stains on the columella, the lip 

 insertion, and along the suture. Whorls eiglit, including the protoconch, 

 which has two small smooth whorls, aud a third larger depre.ssed and 

 crossed by sharp arched riblets. Sculpture: — The adult whorls carry 

 discontinuous prominent spaced ribs, which arise at the suture and 

 continue to the base, those on the spire being perpendicular and set 

 closer together, at the rate of ten to a whorl, those on the last whorl 

 being wider spaced at eight to a whorl, and flexed forward below the 

 shoulder; these cords gradually become smaller and closer; the whole 

 shell is over-run by very fine aud close hair-lines which, decussated by a 

 corresponding spiral sculpture, [)roduces a fine grained surface. Aperture 

 wide, protected by a [)rominent varix ; sinus wide and shallow ; canal shox't 

 and open. Length 9 mm., bieadth 3 mm.

Shell small, ovate-lanceolate, with rounded whorls. Colour orange, 

 with a white median zone. Whorls eight, including a protoconch of three 

 whorls, and of the usual pattern. Sculpture : — On the last whorl are 

 twelve spirals, the anterior ones being fine threads on the snout, aud the 

 median ones represented by cresceutic beads on the riblets ; there are four 

 spirals on the penultimate ; radials discontinuous and perpendicular, 

 amounting to twelve on the last whorl. A pi'oniinent varix extends a free 

 limb towards the aperture; within it are five small tubercles; the pillar 

 lip has two transverse plaits ; canal short ; sinus broad and effuse. Length 

 5'5 mm., breadth 22 mm. 



E. catapasta may be briefly described as a miuiatuie of E. opsi)iiatlies 

 Melvill and Standen,''o with which it closely corresponds in sculptui'e and 

 colour, but from which it differs by being a thii-d of the length, having a 

 whorl less, broader form, and more delicate sculpture.
