transversim tenui striata; anfr. 5, convexis, interdum margin- 



atis; apertura vix obliqua, oblongo ovalis ; labro subrotundato, 



edentate. Pallide rufescente fusca, vel cornea, vel fulvescente. 



Yar. Fasciis tribus, interruptis, cingulata. 



Dimensions. — Long, 17, diam. 10. 



Shell elongately ovate, ratber solid and dull, finely striated 

 transversely ; whorls 5, convex, sometimes marginated ; aper- 

 ture somewhat oblique, oblong oval ; lip flatly rounded, eden- 

 tate. Color plain reddish-brown or yellowish or horn color.

Observations. — 'The above species is decidedly not tseniata, 

 Morch, from the Fiigii's. It is closely allied to P. elongata, 

 Pse., but is shorter, thicker, lip more flat and wider, and colors 

 more plain. 



17. Partula fasciata, Pse.

 nmbilicata, conferte et tenuissime transversim ragoso striata ;

Shell elongate ovate, turrited, rather solid, dull, umbilicate, 

 closely and very finely rugosely striated transversely ; whorls 

 5, roundly convex, last ventricose ; suture well impressed ; 

 peristome widely expanded and reflexed; columella wide,

 except at the sutures. The epidermis is liable to peel off. 



Observations. — -This species is from Marquesas Islands, and 

 quite distinct from any of the Tahitian forms. 



As it has been referred by Mr. Cuming to Ganymedes, Pfr., 

 I fear some change has taken place in labels, or I have given 

 tlie same name to two species in sending to that gentleman.
