interrupts tranversim exculptis ; apertura subquadrata, bre- 

 viter canaliculata. 



Shell elongated, subulate, subturrited, yellow, varying to 

 brown ; whorls flat, longitudinally plicate, traversed trans- 

 versely in the intervals between the folds by impressed lines, 

 of which one larger and deeper than the rest represents the 

 girdle. The intervals between the folds of the superior area 

 is richly painted of a deep reddish brown. A short but 

 distinct canal. 



This is one of those shells with which the earlier Concho- 

 logists were familiar, and it is far better figured by Born than 

 in other more recent works ; indeed, Kiener's figure is scarcely 

 recognizable. Yet though so long known, it continues far from 

 common in collections, and we are ignorant of its native 

 country. Fossils from Bordeaux and the south of 

 Europe have been assigned by Basterot and Bronn to 

 this species.

The girdling is here distinguished by the presence of a 

 punctuation between each fold. The folds are large and 

 broad, and with the interstices striated. The prevailing colour 

 is white, but the shell is handsomely painted with large irre- 

 gular orange-red spots or blotches, and the base and aperture 

 are of the same uniform colour. The last whorl is banded 

 v/ith white. Native country unknown. 



34. T. alveolata. (pi. xlv. f. 120.) Hinds. 1. c. p. 151. 



Testa turrito-subulata, attenuate acuminata, nitida, fusca ; 

 anfractibus subplanulatis, superne cingulo tuberculato cinctis, 

 infra plico-costatis, interstitiis striatis ; cingulo et an- 

 fractu ultimo albo fasciato, maculis quadratis runs arti- 

 culato. 



The description is drawn up from a somewhat young speci- 

 men in the collection of Sir E. Belcher, and the mouth and 

 last whorl have not yet attained their full development. The 

 character of the shell is, however, very conspicuous. In 

 this genus the last whorl will be found very frequently
