Alectrion (Hima) catallus Datt, n. sp. 
Plate 11, figure 11. 
Shell short, solid, acute-conic, pale brown, with a tendency to darker bands, 
whorls eight and a half, of which three and a half are nuclear, rapidly increasing, 
sharply reticulately sculptured; suture very distinct, deep but not channelled ; 
nucleus as in the next species, and the character of the sculpture similar to that 
species, but closer and finer; on the last whorl are about twenty axial riblets 
continuing over the whorl from the suture to the siphonal fasciole; on the spire 
between sutures six, and on the last whorl sixteen strap-like spirals ; aperture 
rounded-quadrate ; outer lip with a strong varix, inside of which about ninetcen 
fine elevated lirae extend into the throat; body with a thick whitish callus and a 
low, rather distant subsutural ridge; pillar short, arcuate, smooth, with one or 
two elongate pustules near the anterior obliquely truncate edge which bears a 
strong keel; canal very short, contracted, strongly recurved, with a longitudinally 
striate siphonal fasciole, behind which, separating it from the base of the whorl, 
is a deep sulcus. Lon. of shell, 14.0; of last whorl, 9.5; of aperture, 6.0; max. 
diam. 8.5 mm.

A very compact and elegantly sculptured shell of the group to which the 4. 
ambigua Montagu belongs, but, like most of the non-littoral species, of a more 
earthy and less porcellanous consistency. The nucleus is of about the same 
character as in the species from moderate depths. 
Alectrion (Hima) miser Da t, n. sp. 
Plate 4. figure 1. 
Shell of moderate size, pale straw-color, with a smooth polished nucleus having ° 
a very minute swollen apex and three and a half rapidly enlarging rounded whorls 
followed by an abrupt change to the adult sculpture, which is borne by about five 
and a half subsequent whorls; shell solid, strongly reticulately sculptured ; suture 
distinct, not channelled; axial sculpture of (on the last whorl about twenty) 
narrow rounded ribs, extending completely over the whorl, with slightly wider 
interspaces and fairly distinct lines of growth; spiral sculpture of (between the 
sutures four and on the last whorl seven) flat, strap-like, elevated bands which 
override the ribs and are about equally elevated in the interspaces as on the 
summits, where on the earlier whorls at the intersections, the intersections are very 
slightly swollen; between the anterior spiral and the siphonal fasciole is a wider 
sulcus ; aperture subquadrate ; outer lip somewhat varicose, thick, with, in the 
adult, eight strong spiral lirae, extending into the throat; body with a thin layer 
of callus and a faint subsutural ridge; pillar very short, concave, smooth, callous, 
with a strong keel just behind its anterior, obliquely truncate edge; axis not
