MANGIUA EVADNE, new species. 



Plate 23, fig. 2. 



Shell small, white, slender, with a smooth swollen nucleus of one 

 and a half whorls and five subsequent whorls; suture constricted, 

 distinct, not appressed, the whorls sloping flatly toward it on both 

 sides; axial sculpture only of faint incremental lines; spiral sculp- 

 ture of one very prominent keel at the shoulder with one smaller and 

 several still finer threads behind it, the anal fasciole smooth; on the 

 last whorl there are two major threads with much wider interspaces, 

 in front of them about six smaller closer threads to the canal which 

 has about six close-set threads and a marked siphonal fasciole ; aper- 

 ture rather narrow^, the anal sulcus deep, rounded, separated by a 

 single thread from the suture ; outer lip thin, produced, sharp ; inner 

 lip erased, pillar straight; canal distinct, rather wide and recurved. 

 Height of shell, 12; of last whorl, 3.5; diameter, 3 mm. Cat. Xo.

This is an odd and extremely distinct species, which recalls some 

 forms of Cryptogemnm^ but is obviously too small for that genus. 



MANGILIA ERIPHYLE, new species. 



Shell small, solid, whitish, acute, fusiform, with one and a half 

 nuclear and six subsequent whorls; nucleus with a minute apex and 

 a swollen smooth globular succeeding whorl; these are followed by 

 a peripherally keeled whorl, the subsequent turns developing two 

 and then three spiral flattish spiral cords, including the peripheral 

 one and in front of it, while behind the keel the surface slopes flatly 

 up to the appressed suture only interrupted by obscure ridges due to 

 the axial sculpture; on the last whorl in front of the anal fasciole 

 there are about a dozen similar cords extending to the end of the 

 canal with about equal channelled interspaces, the posterior two 

 or three cords more or less nodulous at the intersections; axial 

 sculpture of about 10 more or less prominent riblets beginning in 

 front of the fasciole and extending slightly over the periphery on 

 the last whorl becoming obsolete; the incremental lines not con- 

 spicuous: aperture narrowly ovate, the outer lip somewhat varicose 

 with a large shallow rounded anal sulcus close to tlie suture ; within 

 both inner and outer lips are smooth and moderately callous; canal
