200 TORNATELLIDES, NEW ZEALAND, ETC. 



conic, a little higher than the aperture. Protoconch globose. 

 Whorls 5, convex, the last rapidly increasing, ventricose ; base 

 rounded. Suture impressed, faintly and narrowly margined. 

 Aperture subvertical, ovate, angled above. Peristome thin, 

 sharp; outer lip moderately convex, basal lip narrower, 

 arched. Columella vertical, not twisted; inner lip thin, 

 broadly reflexed above, and partly concealing the very narrow 

 and not deep perforation. Parietal wall with an entering 

 median small lamella. Diam. 2.2, height 3.5 mm." (Suter). 



New Zealand: Whangarei (type loc., C. Cooper); near 

 Auckland (H. Suter, S. W. Wright). 



Tornatellina subperforata SUTER, Proc. Malac. Soc. London,

 Mollusca, 1913, p. 769. 



The inflated body-whorl, the straight, not tortuous colu- 

 mella, and the narrow perforation separate it at once from 

 T. novoseelandica Pfr. Type in my collection " (Suter). 



The umbilicus is somewhat smaller than in T. simplex; as 

 usual it penetrates to the first whorl, and is therefore as deep 

 as in other Tornatellides. The parietal lamella is rather short 

 in the adult stage. In the neanic stage, 2.2 mm. long, of 4 

 whorls, the parietal lamella is wider and fully a half-whorl 

 long, and there is a distinct though small and strongly ob- 

 lique lamella near the base of the columella (fig. 14). 



la. T. subperforatus kermadecensis n. subsp. PL 44, fig. 16. 



Shell more slender, with a smaller summit. 



Kermadec Is. : Sunday or Raoul Island (Tom Iredale). 



Mr. Suter has reported T. subperforata from Raoul, col- 

 lected by Miss Shakespear. The single specimen- sent by Mr. 

 Iredale is not adult, but it differs from subperforata of simi- 

 lar length by the narrower contour and more slender apex. It 

 is corneous- whitish ; parietal lamella well developed, fully a 

 half- whorl long; 'columella minutely biplicate. Length 2.5, 

 diam. 1.5 mm., 4% whorls.
