PERNANDEZIA. 97 



Juan Fernandez. Type no. 10166 A. N. S. P. 



This species has more whorls than bulimoides or consimilis, 

 and a smaller aperture. The lateral outlines of the spire 

 are almost straight. 



Named for Dr. T. B. Wilson, who gave the specimens to 

 the Academy. 



6. F. TRYONI n. sp. PI. 14, figs. 12, 13. 



The shell is subimperforate, oblong-conic, thin, translucent, 

 pale yellow, glossy. Spire conic, the apex obtuse and 

 rounded. Whorls 6, but slightly convex. First iy 2 whorls 

 smooth, following whorls of the spire very finely and weakly 

 though quite distinctly striate, the striae curved. Suture bor- 

 dered by transparence. Aperture irregularly ovate, the outer 

 lip obtuse, whitish. Columella rather wide, concave above 

 and excavated below a very oblique fold. Parietal callus 

 thin and straight. Length 6.6, diam. 3 mm.; length of 

 aperture 3 mm. 



Juan Fernandez (no. 10167 A. N. S. P.). 



The smallest species of the group as now known. It is 

 much smaller than F. conifera, with fewer whorls. 



7. F. INORNATA n. sp. PI. 14, figs. 14, 15. 



Shell oblong-conic, imperforate, thin, pale brownish yellow, 

 glossy, somewhat translucent. Spire with very slightly con- 

 vex outlines and obtuse, rounded apex. Whorls 6%, but 

 slightly convex, the first 1% smooth, the rest sculptured with 

 short, low folds below the suture, and very weak, irregular 

 growth-lines. Aperture serrr.jvai, the outer lip white, blunt, 

 with a smooth finish. Columella short, concave above, ex- 

 cavated below the oblique, somewhat lamellar fold. Length 

 9, diam. 4.25 mm. ; length of aperture 4 mm. 



Juan Fernandez (no. 10168 A. N. S. P.) 



Closely related to F. philippiana, but of narrower shape, 

 with a more obliquely entering columellar fold. In the type 

 specimen (pi. 14, figs. 14, 15) this fold is rather weak, but 

 in another shell, which I refer for the present to the same 

 species, it is strong and lamellar.
