BY W. L. MAY. 97 



lowish. Whorls five ; protoconch swollen, with a flat- 

 tened summit. Whorls convex, widest anteriorly. On 

 the body whorl a strong, median keel develops and extends 

 to the lip. There is another small keel on the base. 

 Aperture round, completely margined by a raised edge, 

 and surrounded by a broadly flattened lip. Outer lip 

 strongly varixed behind. 



Length 2. Breadth 0.6 mill. 



Type, with 12 others, from 40 fathoms, off Thouin Bay. 

 An interesting addition to the genus. Nearest in general 

 appearance to E. verconis, Tate, but easily separated by 

 the peculiar keel.

CROSSEA CONSOBRINA, Sp. Nov. 



Shell small, white, rotund, with a small spire. Whorls 

 three and a half, the apical one and a half smooth. The 

 adult sculpture consists of numerous narrow spiral keels, 

 about twelve on the body whorl, separated by spaces of 

 about twice the width. These latter are crossed by nu- 

 merous fine axials, irregularly spaced, forming a delicate 

 cancellation. Base narrowly descending, forming a cor- 

 rugated funicle behind an umbilical crevice. Aperture 

 rounded , the columella lip expanded over the umbilicus, 

 with a. straight edge, developing anteriorly into a broad, 

 flattened projection. Outer lip denticulated by the 

 sculpture. 



Height 1.7. Diameter 1.9 mill. 



Type, with five others, from 40 fathoms, off Thouin Bay. 

 This interesting addition to our fauna is a close ally of 

 C. cancellata, Ten .-Woods, from which it is separated by 

 the very different form of the front of the columella, which 

 in cancellata is rounded, and has a distinct channel, and has 

 also a larger umbilicus, and is more strongly cancellate. 

 It is well figured bv Tate and May, Pro. Linn. Soc, N.S.W., 

 1901. PL XXIII, fig. 1.

CIRSONELLA TRANSLUCIDA, Sp. Nov. 

 Shell small, white, translucid, smooth, except for growth 

 lines, elevated. Whorls three, thei apical very minute, 

 rapidly increasing; the last very large. Aperture large, 

 nearly round, slightly pointed above. Columella lip ex- 

 pands over a deep, narrow umbilicus, sometimes covering 

 it, below which it suddenly contracts, and the expansion 

 is very slight. Outer lip simple, thin, expanded above.
