Trophon longior, n. sp, PL xxi., figs. 5 and 6. 



Shell solid, narrowly fusiform, of seven whorls. Proto- 

 conch of two and a half whorls, smoothly granular, ending 

 by a distinct scar ; first whorl with two carinas, of which the 

 highest continues as a sharp-corded angulation through the 

 embryonic whorls, the lower fades out on the first whorl. 

 Sutures distinct, barely margined. Whorls convex. Aper- 

 ture obliquely oval; canal nearly as long as the aperture, 

 directed obliquely to the left, concave to the right, slightly 

 recurved. Outer lip thin, simple. Inner lip thin, erect an- 

 teriorly. Columella concave, obtusely roundly angled at its 

 junction with the canal. Sculpture bold ; axial costge eleven 

 in the penultimate, rather wider than the interspaces, round, 

 extending from the suture which they undulate to the canal, 

 w^hose varix they scale ; spirals, four in the penultimate, 

 three in the earlier whorls, nine in the body-whorl, 

 round, crossing the axials. Colour white, just tinted with 

 brown ; deeply scorched spirally on the axial costse near the 

 suture, and in the body-whorl just below the periphery. 



Di7n. — Length, 64 mm. ; width, 27 mm. ; aperture, 1*5

 other example, good, but dead. 



Diagnosis. — It resembles Trophon rudolphi, Brazier 

 (taken by me and kindly identified by Mr. C. Hedley), in 

 its striking protoconch, but is longer and narrower, and
