EUGLANDINA. 203 



70. E. TRYONIANA Pilsbry, n. sp. PI. 27, figs. 46, 47. 



The shell is ovate-conic, rather solid, olivaceous, with some 

 faintly darker streaks. Spire conic, with hardly convex out- 

 lines and obtuse summit. The first two whorls are smooth, then 

 fine vertical strise gradually begin; the last four whorls are 

 sculptured with very fine, sharp, unequal strige with scratch- 

 like intervals. There is no spiral sculpture. Whorls 7, mod- 

 erately convex, the last well rounded. Suture well impressed, 

 not crenulate, and appearing margined by transparence, in 

 some lights, but without true margination. Aperture vertical, 

 small, the outer lip forming a regular arch, very blunt, with 

 a pale edge, a trifle arching forward in the middle. Colu- 

 mella short, concave, white. Length 27, diam. 12.5, longest 

 axis of aperture 13 mm. 



Central America (J. S. Phillips), exact locality unknown. 



This species resembles E. undenvoodi and E. chiriquiensis 

 in shape, but differs from them in the fine, sharp sculpture. 

 All of these species are distinguished by the regularly and 

 strongly arcuate outer lip, giving an unusually open shape to 

 the aperture. 



71. E. LANCEOLATA (v. Martens). PI. 27, figs. 38, 39, 40. 



Shell fusiform-lanceolate, thin, irregularly striatulate, some 

 striae more prominent, like varices, glossy, uniform yellow; 

 spire regularly tapering, the apex rather obtuse. Whorls 7, 

 the suture lightly plicatulate and margined, last whorl slowly 

 tapering downwards, slightly more than half the total length, 

 lanceolate; outer margin nearly straight, columellar margin 

 deeply excavated, transversely truncate. Length 30, diam. 

 12, aperture 14.5x7 mm. (Marts.).

"Recognizable by the thin, glossy shell of yellow (not red- 

 dish or brownish) color, and the distinctly attenuated spire."
