traction. Whorls 11, scarce perceptibly rounded. Sidure ex- 

 tremely slight, and only a little oblique. Mouth sbort, broad, 

 and rounded, pointed above, and with a broad sballow patulous 

 gutter iu front. Outer lip well and regularly arched ; it is 

 patulous in front, but direct above ; there its edge retreats very 

 much ; it advances in the middle, and retires again toward the 

 base. Inner lip : across the scarcely convex body there is a glaze 

 with a well-defined edge ; the junction of body and j)illar is 

 obtuse-angled ; the pillar is short, with a rounded patulous edge. 

 H. 0-16. B. 0-05. Penultimate whorl, height 0-02. Tip of apex 

 0-03. Mouth, height 0-04, breadth 0-03. 



This species has not the sharp impressed suture, perfectly 

 flat-sided whorls, and high polish of E. intermedia, Cantr. ; is 

 straighter and more symmetrical, the shell is thinner, the base 

 is narrower and longer, the mouth is larger, the suture is more 

 oblique, the apex is small but more equally rounded, not rising 

 on one side as in that other. It is a good deal like a large form 

 of JE. Jeffrey siana, Brusina, but is slimmer, the whorls are not 

 so rounded, the mouth is very much shorter and rounder, and 

 though the apex is about the same size and form, yet the whole 

 spire is markedly more attenuated. -E'. acerrima is slimmer, 

 longer in the base, narrower in the mouth, and smaller in the 

 tip. E. oxytata, besides other difierences, has a far more at- 

 tenuated spire and minute tip. E. ephamilla is a species with 

 larger whorls and an impressed suture ; but its greater size, the 

 absence of young specimens, and its somewhat damaged tip make 

 minute comparison diflBcult.

Sept. 8, 1874. Minder's Passage, Torres Straits. 7 fms. 



Shell. — Squat, with a broad flat base, a rapidly contracting 

 bent spire, a small tip, convex whorls, an impressed suture, 

 and a small pear-shaped mouth. Sculpture none. Colour glassy 

 white. Apex very small, acuminately symmetrically rounded. 

 Spire small and bent above, enlarging very rapidly in breadth, 

 with concave profile-lines. Whorls 9, short, broad, of slow 

 increase, slightly convex. Suture slight, a little impressed, 

 scarcely oblique. Mouth small, pear-shaped. Outer lip arched, 

 its edge retreats above, is rounded in the middle, and is patulous 

 throughout. Inner lip is continuously arched across the body and 

 down the short broad pillar. H. 0-093. B. 0'04i5, Penultimate 

 whorl, height 0-015. Mouth, height 0-029, breadth 0-019.
