Benson's very incomplete description is given above. The 

 shell is imperforate, cylindric-turrited, with a very obtuse 

 apex; rather solid though thin, straw-colored or greenish- 

 yellow, but slightly translucent, very glossy, sculptured with 

 arcuate and rather weak growth- wrinkles. Whorls 7%, mod- 

 erately convex. Apex rounded, smooth. Aperture oblique, 

 ovate, the outer lip acute, arched forward just below the 

 upper insertion. Columella strongly concave above, w r hite- 

 calloused below, and obliquely truncated at the base, the 

 truncation vertical. Length 20.7, diam. 6 mm., length of 

 aperture 6 mm. 



It is wider and less elongated than T. mandarinus or T. 

 lubricus and is more cylindric and more delicate than T. 

 minis. Specimens from Kuang-tung sent by Mr. B. 

 Schmacker are larger than the form considered typical of 

 erecta by Reeve and Pfeiffer, with 8% strongly convex 

 whorls. One is figured in pi. 2, figs. 24, 25. The lip is ob- 

 tuse, though not thickened outside. Specimens measure: 

 length 24.5, diam. 6.8, aperture 6.7 mm.; length 24, diam. 

 6.7, length of aperture 6.9 mm.
