Webster. — Remits of Dredging. 307 



canal, which is straight, has about eight faint striations. The 

 space between the suture and the first spiral keel contains the 

 anal fasciole ; a 1 in. objective reveals faint radial striations 

 between the keels, also the reticulation of the protoconch. Of 

 two shells before rne I figure the smaller because it is almost 

 perfect ; both shells have five whorls, but the larger has three 

 keels instead of two, the third being introduced near the suture. 

 The sinus of the type is so little damaged that to draw it perfect 

 can scarcely be called reconstruction. Type : Length, 5 mm. ; 

 breadth, 3mm. Larger specimen: Length, 6mm.; breadth, 

 3*3 mm. 



Newtoniella stiria ( = icicle), n. sp. Figs. 5, 5a, 56. 



Shell acicular, pale-yellow, vitreous, with twenty flat whorls, 

 of which three represent the juvenile stage. A 1 in. objective 

 reveals one smooth and two sculptured whorls ; the earlier of 

 these two is finely radially ribbed, the latter has in addition 

 spiral striations. The sculpture of the rest of the shell consists 

 of three faintly jewelled spirals to each whorl except the last, 

 which has four. The apex diminishes in diameter with the 

 beginning of the definitive sculpture. Sutures scarcely marked ; 

 base smooth ; columella spiral, white ; canal sharply turned to 

 the left. The outer lip is damaged ; a side view therefore 

 shows more of the columella than would otherwise be visible. 

 Length, 9 mm. ; breadth, 2 mm. 



Triphora infelix, n. sp. Figs. 6, 6a. 



Shell of fifteen slightly rounded whorls with a five-whorled 

 juvenile apex. Whorls 6 to 8, have two jewelled spirals, a third 

 being introduced between the other two on the ninth, at which 

 time also a line denoting a fourth spiral appears in the suture, 

 developing into a plain spiral on the last whorl. Sculpture : 

 Oval jewels almost vertically above one another, united longi- 

 tudinally and spirally by a raised band. Protoconch keeled near 

 the centre of each whorl and finely radiately ribbed. Sutures 

 distinguished by a slightly deeper groove ; base with two obscure 

 spirals. Shell rotten, the aperture broken beyond reconstruc- 

 tion ; columella wanting. General outline very slightly convex. 

 Length, 6 mm. ; breadth, 15 mm. 



Rissoia pingue ( = plump), n. sp. Figs. 7, 7a, 76. 



Shell white, of four and a half rounded but slightly flattened 

 whorls, of which a very glossy protoconch occupies the first 

 one and a half. Sculpture : Fine spiral lines, three on the third 

 and four on the body whorl above the aperture ; the spirals are
