Miralda austro-pacifica n. sp. Fig. 21. 



Description oj Type Specimen. — Shell ovate, apex blunt. Whorls 5|, 

 flattened, suture deep. Aperture ovate, peristome not continuous. Outer 

 lip thin. Inner lip thin, narrow. Columella with a small oblique plait, 

 not reaching to the margin of the inner lip. Sculpture: Protoconch of 

 1 whorl, smooth. Adult whorls with 3 spiral ribs, increasing to 4 on the 

 penultimate and with a fifth on the base. Upper two ribs nodulous, the 

 remainder smooth. Nodules in the upper row smaller than in the lower 

 row. There are faint microscopic axial growth-lines on the lower portions 

 of the whorls. Colour white. 



Height, 2-2 mm. Diameter, 0-9 mm. 



This species appears to be closely related to Odostomia scopulorum 

 Watson, from Hawaii. 



Habitat. — Dead shells dredged in 10 m. to 30 m. on gravelly bottom off 

 Sunday Island. 



Hinemoa n. gen. 



Shell ovate. Protoconch 1-whorled. Aperture ovate. Columella with 

 a feeble plait. Sculpture of spiral ribs only. 



Type. — Hinemoa punicea Oliver. 



Hinemoa punicea n. sp. Fig. 22. 



Description of Type Specimen. — Shell ovate, apex obtuse. Whorls 4 J. 

 Aperture broadly ovate. Outer lip thin. Inner lip anteriorly raised with 

 a slight umbilical chink between it and the body- whorl. Columella-plait 

 small, oblique. Sculpture : Protoconch of 1 whorl, smooth, polished. Shell 

 with high rounded equidistant spiral ribs, 2 on each whorl, the distance 

 between them equal to their width, and equal to the distance between those 

 on each side of the suture, which is not distinguishable. Three additional 

 low spiral ribs on the base. Otherwise the surface is quite smooth. Colour : 

 Protoconch ruby-red, shining ; shell light pink, whitish within the aperture. 



Height, LI mm. Diameter, 0-6 mm. 



Habitat. — Dead shells dredged in 10 m. to 30 m. off Sunday Island ; not 

 common, but easily overlooked. 



Pyrgulina insularis n. sp. Fig. 23. 



Description oj Type Specimen. — Shell ovate, apex obtuse. Whorls 5, 

 flattened, angled at the suture, which is deep. Aperture rhomboid-ovate. 

 Outer lip thin. Inner lip separated from the body-whorl below, leaving 

 a deep umbilical chink. A feeble plait on the columella within. Sculpture : 

 Protoconch smooth. Adult whorls with rounded longitudinal ribs, about 

 20 on the body- whorl. Interstices nearly twice the width of the ribs. On 

 the body-whorl the ribs terminate at a spiral groove below the periphery,
