Mr. Ancey has identified this species from Cocos Island. 

 He considers Tornatellina pittieri Martens as probably iden- 

 tical. That they are closely related is obvious, and I am dis- 

 posed to concur in uniting them; yet according to the pub- 

 lished figures, pittieri is a somewhat more lengthened shell 

 than cumingiana. 



3. 0. PITTIERI (Martens). PI. 47, figs. 15, 16. 



Shell sinistral, imperforate, conoid-turrite, solid, smooth, 

 glossy, whitish-corneous. Spire elongate, the apex rather ob- 

 tuse ; suture impressed, simple. Whorls 6%, a little convex, 

 the last rounded basally. Aperture slightly exceeding one- 

 third the total length, rather oblique, lanceolate, the outer 

 margin slightly arcuate, thin, convex forwardly, basal mar- 

 gin narrowly rounded, columellar margin strongly arcuate, 

 very distinctly obliquely truncate at the base ; parietal wall 

 provided with a compressed, strong, entering lamella. Length 

 9.5, diam. 4, oblique length of aperture 3.5, width 2 mm.

The type figure is copied, pi. 47, fig. 16. 



A fully adult shell referable to 0. pittieri is figured, much 

 enlarged, on pi. 47, fig. 15. The cuticle is olive profusely 

 streaked and spirally lined with light buff. The apex and 

 sutures are eroded. Within the mouth there is a low but 

 strong entering ridge in the middle of the outer wall. Length 

 10, diam. 4, aperture 4 mm. This shell differs from 0. pit-
