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 are 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, 325 mm. ; breadth, 
3 mm. ; of aperture, | 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. 
4457TRODrillia subplicata. n. sp. Pl. xxvii, fig. 6. 4b 
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 coste, 
equal to the interspaces ; well-marked crowded sinuous accre- 
mental striz ; no spiral sculpture. Light-brown, with a band 
of lighter colour on the middle of the spire-whorls, whitish 
where it crosses the coste; 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. Tedley 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.”
