128 KEY. E. BOOG WATSON ON THE 



Shell. — Eather small, broad, blunt, slightly angulated at the 

 periphery, straight, with conical profiles, flat-sided whorls, a 

 slightly impressed suture, and a small angulated mouth. Sculp- 

 ture. There are unequal, close-set, hair-like microscopic lines of 

 growth, and faint broader spirals. Colour glossy ivory-white. 

 Apex very blunt, rounded, with a slight projection of the extreme 

 tip on one side. Spire short, conical, very slightly contracted 

 toward the apex. Whorls 6, of regular increase ; the last is 

 subangulated at the periphery. Suture somewhat oblique, 

 slightly impressed and distinct. Mouth somewhat lozenge- 

 shaped, being pointed above and at the end of the pillar, and also 

 at the periphery of the shell and the base of the pillar. Outer 

 lip thin, angulated at its edge, retreats above and in front, and 

 is prominent at the periphery. Inner lip : a thinnish defined pad 

 stretches across the body, which is flat and expands thinly on 

 the straight shortish pillar. H. 0"15. B. 0'07. Penultimate 

 whorl, height 0'03. Tip of apex 0-013. Mouth, height 0-05, 

 breadth 0-04. 



This is a remarkably short and blunt form, more like an Odos- 

 tomia, but without the characteristic apex of that genus. 



22. EULIMA DISSIMILIS *, U. Sp. 



April 17, 1874. Port Jackson, Australia. 2-10 fms. 



Shell. — Small, translucent, thin, narrow, straight, cylindrical, 

 with a short spire, a blunt rounded tip, whorls of which the 

 earlier are short and rounded while the last two are high and 

 flattened, an impressed suture, and a round mouth. Sculpture. 

 There are faint unequal microscopic lines of growth. Colour 

 translucent, glossy white. Apex blunt, roundly and evenly 

 pointed. Spire short, cylindrical below, roundedly conical above. 

 Whorls 5J ; above they are short, rounded, and of slow increase, 

 but the last two are somewhat long, cylindrical, and of rapid en- 

 largement ; the base is long, slowly contracted, but at last rapidly 

 rounded. Suture distinct, and constricted above ; below it is less 

 so. Mouth short and round, pointed above, patulous but not 

 guttered in front. Outer lip circularly curved ; its thin edge is 

 quite level. Inner lip is very straight, with a thin definite-edged 

 pad on the body and pillar, the latter of which is short. H. 0*11. 

 B. 0-03. Penultimate whor], height 0-026. Tip of apex 0-009. 

 Mouth, height 0-03, breadth 0027. 



* As not like a Eulima at all.
