ei i solidula, n. sp. Pl. xxv., figs. 7 and 8. bC/ 
Shell small, solid, shining-white, smooth, obliquely 
elongate-oval. Apex blunt, four whorls, sloping convex, 
suture well channelled. Aperture oval, contracting gradu- 
ally to a linear gutter posteriorly, widely open in front, and 
notched; outer lip simple, smooth; inner lip is a narrow, 
thick glaze over the base to the suture, slightly spreading 
over the columella. 
Dim.—Length, 6 mm.; of body-whorl, 4 mm.; width, 
2°3 mm. 
Locality.—Type from 55 fathoms off Cape Borda, with 
1 other; Backstairs Passage, 22 fathoms, 3 specimens; Gulf 
St. Vincent, (?) depth, 3, none alive; Venus Bay beach, 1. 
Diagnosis.—It differs from O. triticea, Duclos, in havy- 
ing fewer whorls, being more solid, not so contracted anter- 
iorly, and in not having a wide callus winding from the inner 
lip over the front of the dorsum; from O. exquisita, Angas, 
which it closely resembles, in being smaller, narrower, and

-Ancilla beachportensis, n. sp. Pl. xxiv., fig. 9. EEO 
Shell solid, oval, of 4 whorls. Apex markedly papillate. 
Spire completely covered with callus, almost obliterating the 
sutures, which are indicated by shallow furrows, between 
which over each whorl are some three low, broad spiral 
ridges. Aperture triangularly-oval, narrow behind, widely 
open in front, truncated, and widely notched. Outer lip 
simple, thin, with a callous thickening in its upper sixth, and 
with a tooth near its anterior end. Inner lip a thick callus, 
extending beyond the aperture, and up over the spire, where 
it recedes in steps just above each sutural groove. Columella 
nearly straight, truncate, with six oblique curved plaits in 
front. The body-whorl has two approximate grooves, wind- 
ing round its base from above the middle of the aperture, the 
upper one to the labral tooth, the lower to just above the 
notch; a third lies above a band of callus extending from 
just above the columellar plaits to the left pillar of the notch ; 
another groove bounds, at its lower edge, the spiral callus 
which spreads down from the suture and thickens the back 
of the outer lip. The body-whorl between these grooves has 
sublenticular axial and spiral scratchings, and has a faint- 
bluish-grey tint, whereas the callus is milk-white. 
Dim.—Length, 20° mm.; of the aperture, 12 mm.; 
width, 95 mm. 
Locality.—Type from 110 fathoms off Beachport, with 
9 others.
