SUTEE : ON MOLLTJSCA FROM NEW ZEAIANB. 257 



Hab. — Hohoura Bay, North Island (R. Buddie). Type in my 

 collection. 



ToRNATINA TENUILIEATA, n.Sp. PL XI, Fig. 13. 



Tornatina pachys, Watson: Murdoch & Sutei', Trans. N.Z. Inst., 

 vol. xxxviii, p. 280 ; not of AVatson. 



Shell small, cylindrical, mucronate, thin, white, with microscopic 

 spiral striae on the lower half. Sculpture consisting of distinct, fine, 

 curved growth-lines and inequidistant microscopic spiral lines on the 

 anterior half of the body-whorl. Colour white. Spire depressed, 

 almost flat, the nucleus only projecting above the last whorl. Proto- 

 conch papillary, smooth and glossy, tilted. Whorls 4, narrowly 

 angled above, the last cylindrical, but little narrowed below. Suture 

 channelled. Aperture vertical, nearly as high as the shell, very 

 narrow above, prominently widened below. Outer lip thin, shai^p, 

 narrowly rounded above, somewhat advancing at the middle, regularly 

 convex at base. Columella slightly oblique, with a deep-seated fold, 

 forming an inconspicuous angle with the moderately convex parietal 

 wall ; inner lip spreading over the latter as a very thin glaze. 

 Diam. 1'6, height 3-2 mm. 



After careful comparison with Watson's description and figure 

 I have come to the conclusion that this species is decidedly distinct. 

 I also wish to state that the wrong identification rests with me alone.

Shell (Fig. 14) auriform, subquadrangular, thin and fragile, spirally 

 finely striated, white. Sculpture the same as in the species. Colour 

 white, iridescent in some parts. Periostracum very thin, transparent, 

 shining. Spire sunken, the outer lip narrowly reflexed over the centre. 

 Body-whorl very large, flatly convex, open from below. Outer lip 

 narrowly convex and projecting beyond the spire above, forming a deep 

 sinus with the body, very little convex in the middle, rounded on 

 joining the basal lip, which is oblique, straight, or lightly convex, 

 regularly arched toward the oblique, high, arcuate, and very thin 

 columella ; inner lip very thin, spreading broadly beyond the pillar 

 and upon the short, strongly convex parietal wall. 



Diam. maj. 7, min. 3-5 ; height 8-8 mm. Type. 



,, 12 ,, 6 ,, 13-5 ,, Large specimen. 



Animal (Fig. 15) flattened, elongate, yellowish-white, the head-disc 

 oblong, with a distinct longitudinal median groove, much longer than 

 the posterior quadrangular mantle -shield, which entirely covers the 

 shell. The parapodial lobes long, but not high. 



The masticatory plates (Fig. 17) are lozenge-shaped, devoid of 

 perforations, dark brown, outer surface hollowed, with a central
