270 TORNATELLAR1A. 



species appears to be closely related to T. abbreviate*, of East 

 Maui. It differs, however, in its more conical spire with 

 more convex whorls, smaller umbilicus and lower parietal 

 lamella. 



The species is dedicated to Mr. E. A. Smith of the British 

 Museum. 



The specimens from Kaiwiki differ somewhat from the more 

 widely distributed form. They are more obese, measuring 

 length 3.6, diam. 2.7 mm. The parietal lamella is lower, about 

 0.10 mm. in height. There are two color varieties of this 

 form; the typical vitreous-corneous and a single specimen 

 of a uniform darker corneous color. 



15. T. SHARPI P. & C., n. sp. PL 55, fig. 10. 



The shell is perforate, rather broadly ovate-conic, light- 

 cinnamon; glossy, very weakly striate. Outlines of the spire 

 barely convex. Whorls 6%, convex, the last rotund. Parietal 

 lamella rather high, excised in front. Columellar lamellae two, 

 subequal, the upper emerging to the edge, the lower slightly 

 shorter. Length 3.3, diam. 2.2, aperture 1.4 mm. 



Hawaii: crest of Kilawea crater, about half a mile south 

 of the Volcano House, Dr. Benj. Sharp. 



Similar to T. abbreviata hawaiiensis, but decidedly smaller. 

 T. stokesi of Oahu is less conic in shape. The authors collected 

 over about the same ground in 1913 without finding this 

 species. 



16. T. BALDWINIANA C. & P., n. sp. PL 55, fig. 5. 



The shell is perforate, ovate-conic, corneous, transparent, 

 shining, under a lens distinctly and almost regularly striate 

 with lines of growth. Spire convexly conic, apex subacute. 

 Suture simple, well impressed, indistinctly narrowly mar- 

 gined and minutely crenulate. Whorls 6%, convex, increas- 

 ing slowly and regularly, the last tapering towards the base. 

 Aperture proportionately large, oblong-ovate. Parietal la- 

 mella low, entire, scarcely diagonal. Columella tumid above, 

 with two low folds, the upper slightly stronger than the 

 lower. Peristome thin, acute, uniformly arcuate. Length 3.4,
