sinus deep, rather narrow, separated from the suture by a 

 distince equal to its width, then convex, with an anterior 

 shallow sinus at the base of the canal. Inner lip inconspicu- 

 ous, applied, smooth, with a callosity at its junction with 

 the outer lip. Sculpture: the first two whorls are closely, 

 regularly, validly, axially costulate, the rest rudely ribbed in 

 the anterior two-thirds ; ribs oblique, rounded, rather wider 

 than the interspaces, becoming- less marked and more distant 

 on the body-whorl, and almost absent on the base, about 14 

 in the penultimate ; sublenticular accremental incisions. 

 Spiral incisions ai'e deep, irregularly slightly wavy, about 8 

 in the penultimate, and 20 in the body-whorl, nearly equi- 

 distant, in places alternately fine and wide. Colour uniform 

 light-straw tint. 



Dim. — Length, 8'5 mm. ; of aperture, 3'25 mm. ; breadth, 

 3 mm. ; of apertiire, 1 mm. 



Locality. — Type in 40 fathoms off Beachport ; in Gulf 

 St. Vincent, depth unrecorded, 7 fresh and dead; in 17 

 fathoms Backstairs Passage, 1 alive, 2 dead. 



Drillia subplicata. n. sp. PL xxvii., fig. 6. 



Shell short, solid, narrowly oval, with a blunt apex and 

 slightly contracted base. Protoconch of two smooth, slightly 

 convex whorls. Spire-whorls four, sloping scarcely convex. 

 Sutures linear. Aperture oval, slightly contracted behind, 

 opening widely into a very short canal in front. Outer lip 

 simple ; with a shallow, round sinus near the suture, a con- 

 vex profile, and a very faint sinus anteriorly. Inner lip a 

 complete, applied narrow glaze. Columella straight, slightly 

 bent to the left in the canal. Faint oblique axial costae, 

 equal to the interspaces ; well-marked crowded sinuous accre- 

 mental striae : no spiral sculpture. Light-brown, with a band 

 of lighter colour on the middle of the spire-whorls, whitish 

 where it crosses the costae ; three light bands on the body- 

 whorl. 



Dim. — Length, 7 mm. ; breadth, 3 mm. 



Locality. — Type 40 fathoms off Beachport ; 110 fathoms, 

 1 moderate ; in 130 fathoms off Cape Jaffa, 1 poor. 



Diagnosis. — Mr. ITedley writes: — "This is not my D. 

 nenia. Yours lacks the ribbing of my shell, is broader, and 

 more solid, the notch is shallower, and the canal shorter."
