556 FUNAFUTI ATOLL. 
nodose lyra, then a furrow, followed by the smooth raised margin 
of the narrow oblique umbilicus. Aperture, oblique, circular 
with a double lip, one within the other, and an expanded, trifid 
wing-like varix. Length 1:6; breadth 1:4 mm. 
One specimen dredged off Tutaga Islet in 50 — 60 fathoms. 
Named in honour of Mr. G. H. Halligan, who procured most 
of the deeper water species mentioned in this supplement. 
EULIMA DIAPHANA, sp. nov. 
(Fig. 69.) 
Shell narrow, subulate, transparent. Whorls seven, 
rapidly increasing, wound more obliquely as the growth 
proceeds. Surface smooth, most glossy, through it is 
seen every detail of the columella. Aperture some- 
what claw-shaped, narrow and curved, acuminate 
posteriorly, broadest and truncate anteriorly. Outer 
lip sharp sinuous. Columella slightly curved, spread- 
ing a callus on the preceding whorl. Length 1°'8; 
breadth ‘44 mm. 
One specimen dredged at 45 — 52 fathoms off Tutaga. 
This species appears to be widely different from any 
hitherto figured. 
EULIMA SAMOENSIS, Crosse. 
Tryon, Man. Conch., viii., 1886, pl. Ixx., fig. 78. 
One specimen collected by Mr. W. Poole on the lagoon beach 
was by him presented to the Australian Museum. The species 
was previously only known from Samoa. 
ODONTOSTOMIA ROBUSTA, sp. nov. 
(Fig. 70.) 
Shell small, strong, ovate. Colour white. 
Whorls four ; exclusive of the smooth, prostrate, 
heterostrophic two-whorled apex. Sculpture— 
sixteen strong, smooth, outstanding, longitudinal 
ribs sinuate the suture and reach to the extreme 
point of the base. Similar ribs extend con- 
tinuously across the upper whorls. Between 
these ribs appear the broken lengths of about a 
dozen, delicate, widely parted, raised, spiral 
threads. Aperture ear-shaped, effuse anteriorly. 
Columella massive, entering in a strong, spiral 
twist. Lip formed by the last rib. Length 1:2; 
Fig. 70. breadth -65 mm. 
One specimen dredged off Tutaga Islet in 45 — 52 fathoms.
