Genus Peculator, Iredale, 1924 



Type (original designation): Peculator verconis, Iredale, 1924 



Peculator coma (Odhner, 1924). 



1924. Marginella coma, Odhner. N.Z. Mollusca, Papers from Mortensen's Pacific Exped. 



1914-1916, No. 19, p. 42. 

 1926. Peculator ("distantly related to") coma, Odhner. Finlay, Trans. N.Z. Inst., lvii, p. 434. 



Odhner 's type came from 10 miles north-west of Cape Maria van Diemen. Identical 

 specimens were taken at Sts. 929, 931 and 932. Dead shells are pure white as the holotype, 

 but fresh material shows a coloration of orange-brown with irregular laterally elongate 

 splashes of light buff. 



A closely allied species is Mitra hedleyi, Murdoch, 1905. This shell agrees with coma 

 in the details of protoconch, sculpture and even coloration, the main difference between 

 the two being the much narrower proportions of hedleyi. 



Family PYRENIDAE 

 Genus Zemitrella, Finlay, 1926 

 Type (original designation) : Lachesis sulcata, Hutton 

 Zemitrella sericea, n.sp. (Plate LVI, fig. 3). 



Shell small, elongate subcylindrical, thin, pale buff; protoconch, first post-nuclear 

 whorl and base unevenly stained with light brown. Surface silky in appearance, caused 

 by exceedingly fine, dense and regular, axial growth striae on a microscopically pitted 

 surface, the minute punctures being arranged in dense regular spiral series. Whorls 

 five, including a papillate protoconch of 1 J whorls, the tip slightly oblique and the whole 

 surface covered with the microscopic punctate-striae. Spire tall, about ij times height 

 of aperture. Whorls evenly and lightly convex. Body whorl subcylindrical. Aperture 

 narrow, slightly channelled above and narrowly notched below. Outer lip thickened 

 medially but thin at extreme edge. Pillar straight medially, but deeply concave over 

 parietal wall and sloping obliquely to left below. A weak plait borders this inner edge of 

 the base of the pillar. The neck or lower part of the base is sculptured with seven fairly 

 distinct oblique rounded spiral cords with linear interspaces. The uppermost of these 

 cords is strongest and the lowest almost obsolete. 



Height 3-5 mm.; diameter 1-45 mm. (Holotype). 



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



Quite distinct from any of the described species in its silky surface. 



Zemitrella annectens, n.sp. (Plate LVI, fig. 4). 



Shell small, elongate-fusiform, thin, white. Surface silky, caused by exceedingly fine 

 and dense axial growth striae, similar to that of the previous species except that the 

 axial striae are still finer and there is no spiral series of punctate-striae. Spire tall, a little
