FERNANDEZIA. 99 



There is some doubt whether the species described and 

 figured by Pfeiffer is identical with that of Anton. Anton 

 gives the locality "Opana," meaning the island Opara or 

 Rapa, one of the Austral Group. He gives the shell 5 whorls. 

 Pfeiffer 's description follows: 



"Shell ovate-conic, thin, striatulate, glossy, olivaceous- 

 corneous; spire conic, apex rather acute. Whorls 6 to 7, a 

 trifle convex, the last about as long as the spire. Columella 

 twisted, very obsoletely truncate. Aperture oblong-oval; 

 peristome simple, acute, columellar margin reflexed in a callus 

 which often spreads outwardly. Length 7.5, diam. 3.5, 

 aperture 3.5 mm. long, 1.66 wide." 



"Island of Juan Fernandez (Cuming)." 



This form was also recorded by Mr. Smith as collected on 

 Juan Fernandez by the Challenger expedition. 



Pfeiffer's figure in the Abbildungen of Philippi is copied, 

 pi. 14, fig. 9. Reeve's figure agrees with this except that the 

 columella is more curved and prominent at the base. In the 

 Concliylien Cabinet Pfeiffer figures a more ventricose and 

 Bulimoid shell, which certainly looks like a different species, 

 but gives the same description. I have copied this figure 

 also, pi. 14, fig. 10. 



10. F. LONGA n. sp. PI. 14, fig. 6. 



The shell is imperforate, oblong-turrite, thin, pale brown- 

 ish-yellow, somewhat transparent, glossy. Spire long, with 

 nearly straight sides, the apex obtuse and rounded. Whorls 

 7!/2, but slightly convex, the first 1% smooth, the rest regu- 

 larly sculptured with straight vertical, fold-like striae, which 

 weakly crenulate the very narrow prominent border below 

 the suture. The striaa became less regular on the last whorl 

 or two, and the sutural border loses its prominence. In some 

 places a very minute spiral striation may be made out in 

 favorable light. The aperture is irregularly ovate ; outer lip 

 simple; columella subvertical above and somewhat excavated 

 below the low, oblique, sublamellar fold. Length 9.9, diam. 

 4 mm. : length of aperture 4 mm.
