42. T. CASTA, (pi. xliv. f. 84.) Hinds, 1. c. p. 156. 



Testa obeso-subulata, subturrita, albescente, leevigata? 

 polita; anfractibus integris, planulatis, superne plicatis et 

 lacteo fasciatis, infra Isevigatis, strigis longitudinalibus pallide 

 fuscis nebulosis ; anfractu ultimo sub-elongato, lacteo fasciato 

 columella brevi, subrecta ; canali nullo. 



The milky white colour is broken by longitudinal markings 

 of a pale brown ; a narrow l^anding, however, of uninter- 

 rupted white transverses the superior part of each whorl, and 

 also the last whorl. The folds are delicate and numerous, 

 disappearing towards the middle of the whorl. Aperture 

 effuse. Columella truncate. No canal. Tliis species is not 

 girdled, though from the distribution of the colouring, it 

 might at first appear so ; and it will thus be readily distin- 

 guished from T. rajihanula, Avhich is decidedly so.

43. T. RUDis. (pi. xliii. f. 60.) Gray, 1. c. p. 60. T. Petitii, 

 Kiener, 1. c. p. 37, t. 13, f. 32. 



Testa elongate conico-subulata, acuminata, turrita, pallida ; 

 anfractibus planulatis, subangustis, superne sulco divisis ; plicis 

 subrectis, brevibus, lineis duabus vel tribus impressis decus- 

 satis ; apertura utrinque attenuata ; columella nuda, contorta ; 

 breviter canaliculata. 



So closely allied to 7'. plicata, that description must fail to 

 distinguish them ; yet on comparison, they are conspicuously 

 distinct. The present is more elongated and coarser, the 

 M'horls are narrow and provided with short solid ribs, nearly 

 or quite straight ; and these are crossed by two, or perhaps 

 three transverse lines. T. plicata is highly polished, the ribs 

 are longer, delicate and sharp, placed somewhat at a 

 distance, and very regularly crossed by three or sometimes 

 four lines. New York and Philadelphia : Kiener. 



44. T. PLICATA. (pi. xliii. f. 61.) Gray, 1. c. p. 61. 



Testa conico-subulata, acuminata, turrita, pallida, nitida ; 

 anfractibus planulatis, superne cingulatis, longitrorsum ])lica- 

 tis ; plicis acutis, subarcuatis, transversim lineis definitis, 

 circa quatuor, exsculptis ; apertura oblonga, subquadrata ; 

 columella nuda, contorta, acuta ; breviter canaliculata. 



Shell conical subulate, acuminate, turrited, of an uniform 

 pale cream-colour, shining ; whorls flat, with slightly sinuous 

 folds, girdled above, with about four transverse very regular
