of Neptune Islands, with 9 good and 24 poor; also in 40 
fathoms off Beachport, 3 fresh; in 90 fathoms off Cape Jaffa, 
1 good, 3 poor; in 110 fathoms off Beachport, 1 good, 1 poor ; 
in 130 fathoms off Cape Jaffa, 3 moderate. 
When fresh there is a walnut-coloured band over the 
middle third of the body-whorl, less extensive in the inter- 
costal spaces. This appears above the suture in the spire- 
whorls; the coste are dotted above, and there are curved 
axial lines of dots on the lire at the base. The size may 
reach to—Length, 73 mm.; of the body-whorl, 3°6 mm. ; 
breadth, 3mm. The ribs in the longer form may be much 
narrower, and may be obsolete before reaching the body- 
whorl. i 
This species approaches very close to Mangilia, and may 
belong to that genus.

Shell, minute, solid, of 44 whorls, including a blunt pro- 
toconch of 2 whorls, which are convex and apparently smooth, 
but microscopically granular, separated by a linear suture; 
it ends abruptly, and from within it issue the spirals of the 
first spire-whorls. Perfect specimens show the granules in 
very close-set spiral rows. Spire-whorls slightly convex, with 
eight spiral lire. Sutures simple. Body-whorl large, taper- 
ing anteriorly. Aperture elongate-oval, rather widely open 
in front; outer lip simple, crenulated outside by the sculp- 
ture, slightly convex in profile, with a minute round, shallow 
sinus close to the suture; inner lip is a complete narrow 
glaze; there are twenty-three spiral lire, flat-topped, half 
as wide as the interspaces, axially faintly incised. Colour is 
cinnamon-brown, lighter in a band on the prominence of the 
whorls. 
Dim.—Length, 3 mm.; of the body-whorl, 2°1 mm.; 
breadth, 135 mm. A second example is 3°8 mm. by 1°5 mm. 
Locality.—Type from Gulf St» Vincent, depth unre- 
corded, with 70 others in good and moderate condition ; in 22 
fathoms Backstairs Passage, 4 alive, 5 dead. 
It is not unlike Plewrotoma (Thesbia) eritima, Watson, 
Chall. Reps. Zool., 1886, vol. xv., p. 329, pl. xxiii., fig. 2, 
but is larger and has spirals half, instead of twice, as wide 
as the grooves.
