This species seems to have been first collected by Blanchet, who 

 sent specimens to Moricand. The latter took them for a bandless 

 variety of clausus Spix ; so that what he actually recorded in vol. vii 

 of the Memoirs of the Geneva Society was turbinatus, though from 

 the record there given it would appear to be clausus; the true state 

 of affairs was seen by Beck, but no explanation was made public 

 until Moricand's Third Supplement appeared, which, although sub- 

 mitted to the Geneva Society in May, 1845, was not published until 

 1846, and, therefore, after Pfeiffer had described the species as T. 

 turbinatus.

Shell compressed-turbinate, with a rather short, arcuate umbilical 

 suture, thin, brownish-corneous, sculptured with light growth- 

 wrinkles and delicate spiral lines. Spire conic, the apex obtuse ; 

 whorls 4^, convex, the last but little distorted, deeply constricted and 

 grooved behind the basal lip, having an oblique, curved impression 

 behind the outer lip. Aperture small, slightly oblique, subtriangular, 

 nearly closed by seven lamellae and folds, the angular lamella run- 

 ning out to the end of the upper lip and somewhat connected there- 

 with, the plate-like fold within the outer lip very deeply entering.

Smaller than T. turbinatus, with fewer whorls and a more deeply 

 entering palatal fold. The umbilical chink is arcuate. The follow- 

 ing form is hardly separable, even as a variety.
