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. UOV. 

 (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, pi. 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.
