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 carine, 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 coste eleven 
in the penultimate, rather wider than the interspaces, round, 
extending from the suture which they undulate to the canal, 
whose 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 coste near the 
suture, and in the body-whorl just below the periphery. 
Dim.—Length, 64 mm. ; width, 2°7 mm.; aperture, 1°5

Locality.—Type in 40 fathoms off Beachport, with one 
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
