256 TORN ATELL ARIA. 



1. T. LILJ5 C. &. P., n. sp. PI. 54, figs. 1, 2. 



Shell narrowly and deeply umbilieate, ovately turrited, dark 

 corneous, dull, very closely and lightly striated, quite thin. 

 Spire conic. Outlines very slightly convex, apex subacute. 

 Suture simple, hardly impressed. Whorls 7y 2 , nearly flat, 

 the embryonic convex, the last angular at the periphery, with 

 a slightly convex, very short base. Aperture broadly trun- 

 cate ovate, rather small. Parietal lamella low, oblique. 

 Columella simple, expanded over the umbilicus, furnished with 

 two scarcely oblique, thin, corneous folds ; the upper stronger 

 than the lower and extending nearly to the margin of the 

 columella. Peristome thin, above the obliquely angled peri- 

 phery nearly straight, arcuate below. Length 3.9, diam. 2.5, 

 axis of apert. 1.5 mm. Height of parietal lamella 0.14 mm.

 Type locality, ridge west of Kolekole Pass on the Leilehua 

 side. Type no. 18424 Bishop Museum, cotypes 13666 B. P. B.

Belated to T. newcombi, but broader in proportion to its 

 length, with a larger umbilicus, flatter whorls, of which the 

 last, in adult specimens, is angular at the periphery, and a 

 much shorter base. It is wider than T. adelince, and differs 

 by the angulation. 



In T. lilce the umbilicus is larger relative to the diameter 

 of the shell than in any other species of the genus except 

 T. adelintz, being %-% of the basal diameter. The upper 

 columellar fold is stronger than the lower. The embryonic 

 whorls are encircled with about 10 spiral striae. The parietal 

 lamella is 0.14-0.22 mm. in height and is minutely serrate 

 along its margin. 



2. T. ADELINE P. & C., n. sp. PI. 54, figs, 3, 4. 



The shell is umbilieate (width of umbilicus contained nearly 

 six times in the diameter of the base), pyramidal, pale brown ; 

 very finely but sharply striate. Outlines of the spire are 

 barely convex, nearly straight, the individual whorls being 

 very slightly convex. Apex rounded. The last whorl is 

 rounded peripherally and most convex around the umbilicus.
