Shell club-shaped, with rather long spire and slender canal, white, thin, rather smooth. 

 Whorls 6 or 7, of which about i 1 /., nuclear ones, form a smooth convex-whorled top; sub- 

 sequent whorls convex, separated by a conspicuous but shallow suture, angular about the middle 

 of upper whorls, obliquely declining from suture till angle, nearly straight below the angle and 

 somewhat narrower at the lower suture. Varices laminar, 1 2 on last whorl, each on the angle with 

 a hollow spine, which is slightly directed upwards, body-whorl with about 6 obtuse spiral lirae, of 

 which the upper one at the angle unites the spines, the other lirae make the margin of varices 

 undulate, 2 or 3 lirae are visible on the upper whorls. Aperture ovate, with arched, thin peristome, 

 interiorly slightly thickened, smooth, white: columellar margin with a thin, appressed layer of 

 enamel. Canal long, directed towards the right, sculptured by the continuation of the varices.

This species much resembles T. Goodrichi Forbes, as figured by Sowerby (Thes. Conch. 

 Vol. IV, Trophon, PI. I), but the spire of the new species is higher, the canal is less tortuous, 

 above all the species has been described as smooth, I see in the figures no traces of spiral 

 lirae or undulated varices. Many of the hollow spines are broken in the largest specimen, that 

 has served for description and in that specimen the nuclear whorls are wanting. One of the 

 specimens from Stat. 271, has a more oblong shape and the lirae have disappeared, as however 

 the 2 accompanying specimens, though young, agree with those from other localities, I think 

 these differences will be only individual, the wanting of lirae will probably be due to the state 

 of erosion of this specimen, which contains however the soft parts. 



The radula has a median tooth (M) with broad base of which the anterior margin is 

 convex in the centre and at the sides, the posterior one has sharp angles ; of the five denticles 

 the distal ones are larger than the median cusp, with a small intermediate denticle on each 

 side; the laterals (1) have a rather narrovv base and a slender cusp, a little curved at the point. 

 Number of rows a little more than 100.

Shell fusiform, thin, white, with moderately long spire. Whorls 7, of which about i 1 /, 

 convex, smooth ones form the nucleus. Subsequent whorls convex, angled above the middle, 

 convexly declining above the angle, contracted towards the deep suture. Sculpture consisting 

 of fine laminate varices, 14 — 16 on last whorl; these are simple above the angle, where they 

 form free laminae; at the angle they form open spines, which are directed outwards and are 

 slightly upturned, below the angle are 2 rather obtuse lirae on the upper whorls, 5 or 6 on 

 last whorl; in being crossed the laminae bear short spines, decreasing to scales near the base 

 of last whorl. Canal moderately long, with nearly straight lamellae, corresponding to those of 

 last whorl. Aperture triangularly rounded, upper margin convex, outer margin slightly thickened 

 at some distance from the thin rim ; columellar margin enamelled, appressed; canal open.
