spaces varying from two to four times the width of the threads. Whorls 2f, protoconch 

 minute, smooth, inrolled. Outline of whorls bicarinate, flattened above and below but 

 lightly convex between the carinations. Carinations as moderately strong rounded cords 

 which are crenulated by the traversing of the radials. Aperture squarish. Peristome 

 thin, continuous, retractive towards parietal wall. 



Height 0-4 mm.; major diameter i-i mm. (Holotype). 



Habitat: Off Three Kings Islands, St. 933, 260 m. 



This species closely resembles bicarinata (Suter, 1908) in shape, but instead of being 

 smooth it has close radial sculpture, which crenulates the keels. 



Family PYRAMIDELLIDAE 

 Genus Eulimella, Jeffreys, 1847 



Eulimella aupouria, n.sp. (Plate LIV, fig. 9). 



Shell minute, subulate, smooth and polished, semi-transparent white, imperforate. 

 Whorls six, plus a heterostrophe protoconch of two convex smooth whorls. Spire 

 about 3! times height of aperture; outline of whorls very lightly convex, slightly 

 flattened in the middle. Suture lightly impressed, false-margined below. Aperture 

 narrowly ovate, peristome simple, outer lip thin but somewhat thickened at the 

 columella. 



Height 2-25 mm.; diameter 0-58 mm. (Holotype). 



Habitat: Off Three Kings Islands, St. 934, 92 m. 



This and the next species have been separated as new by Dr C. R. Laws who has 

 prepared a monograph of the New Zealand pyramidellids. 



Genus Chemnitzia, d'Orbigny, 1893 

 Type (fide Dall and Bartsch) : Turbonilla inaspectus, Fuchs 



Chemnitzia lawsi, n.sp. (Plate LIV, fig. 8). 



Shell minute, subulate, semi-transparent, polished, white, imperforate. Whorls 6\, 

 plus a heterostrophe protoconch of two whorls, the apex being tilted and almost im- 

 mersed by the first post-nuclear whorl. Spire tall, about 3^ times height of aperture; 

 outline of whorls lightly convex. Post-nuclear sculpture of strong regularly spaced 

 rounded axials with excavated interspaces equal to the ribs in width and terminating 

 just above the suture, the base being smooth. The axials number about sixteen per 

 whorl. Aperture narrowly ovate; peristome thin and sharp, nowhere thickened. 



Height 2-35 mm.; diameter o-6 mm. (Holotype). 



Habitat: Off Three Kings Islands, St. 934, 92 m.
