30. T. stylata. (pi. xliv. f. 79.) Hinds, 1. c. p. 152. 



Testa subulata, acuminata, polita, olivacea ; anfractibus 

 subplanulatis, integris, numerose plicatis, infra evanidis, prope 

 suturam albidis maculis fuscis interrupts fasciatis, ultimo lsevi- 

 gato, inferne albo anguste fasciato : apertura fusca ; columella 

 laevi, subtruncata. 



The whorls are undivided, and at their upper part furnished 

 with numerous small, almost capillary folds, which disappear 

 about the middle, leaving the inferior portion quite smooth, 

 and, at the sametime, of a paler colour. The folds are crossed, 

 just beneath the suture, with transverse narrow dark spots. 

 The aperture is much darker than the rest of the shell.

31. T. castanea. (pi. xliii. f. 59.) Kiener, 1. c. p. 19. 

 t. 7- f. 14. 



Testa elongate conico-subulata, subturrita, nitida, castanea ; 

 anfractibus planulatis, sulco impresso divisis, longitrorsum 

 acute plicatis; interstitiislaevigatis ; apertura superne attenuata ; 

 columella nuda, rectiuscula, subtruncata ; canali nullo. 



The folds are separated by distinct smooth spaces, and are 

 sharp and nearly straight ; the girdling is effected more by the 

 cessation of the folds, than by any constriction. The colour 

 is a very dark chesnut, with sometimes a slight appearance of 

 white near the sutures ; the last whorl is banded by white, and 

 its base is somewhat tubercular.
