172 TORNATELLINA. 



29. T. PONAPENSIS P. & C., n. n. 



Shell imperforate, elongate, ovate-conic, thin, pellucid, de- 

 licately striatulate, a little shining, pale buff-corneous. Spire 

 rather high, the apex a little obtuse. Whorls 4%, a little 

 convex, the last as long as the spire. Aperture rather oblique, 

 narrowly oval; peristome simple, acute. Parietal lamella 

 rather strong, high, spirally entering a long distance. Colu- 

 mella subtruncate, strongly twisted, provided with a low, 

 spirally receding lamella. Alt. 2.5, diam. 1.5 mm. (Mlldff.). 



Caroline Is,: Ponape (Etscheid). 



Tornatellina pusilla MLLDFF., Journal of Malacology, vii, 

 March 24, 1900, p. 114. Not T. pusilla Gould. 



An unfigured species of uncertain relationships, perhaps 

 belonging near T. nitida. 



30. T. GAYI C. & P., n/sp. PI. 42, fig. 3. 



The shell is narrowly ovate, brownish-corneous, very thin, 

 fragile, transparent, nearly smooth, minutely marked with 

 growth-striae. Outlines of the spire narrowly ovate, summit 

 smooth, somewhat obtuse. Suture well impressed, faintly 

 margined. Whorls nearly 4^, somewhat convex, the last 

 ovate, tapering towards the base. Aperture subauriform. 

 Parietal lamella minute. Columella nearly straight, slightly 

 sigmoid, without a superposed median lamella. Outer mar- 

 gin of aperture thin, arcuate. Length 1.9, diam. 1.0, length 

 of aperture 0.7 mm. 



Kauai: Makaweli, under dead leaves (Cooke). 



Only three specimens of this species were taken, all of 

 which are adult. It is the smallest species of the genus so 

 far reported from the Hawaiian Is. T. gayi seems to be re- 

 lated to T. cylindrica it is smaller, the outlines of the spire 

 are more convex, and the parietal lamella is much less devel- 

 oped. The species is, for the present, located in section Torna- 

 telUnops, but this position is provisional, pending the dis- 

 covery of young shells.
