MITRA. 35 



470. mica (f. 591), Reeve. — Like M. exarata, banded with 

 dark chocolate brown, but differing in being narrower and 

 more pyramidal. 



471. ligata (f. 584), A. Adams. — The body whorl does 

 not slope downwards, as in M. exarata, but is more cylin- 

 drical. 



472. rubella (f. 594), Adams et Reeve. 



473. scitula (f. 418), A. Adams. 



474. intertjeniata (f. 154), Sowerby. — Shaped like M. 

 rectilateraMs. The lower part of the last whorl is contracted, 

 and the linear markings do not run over the ribs. 



475. Michaudi (f. 157), Crosse et Fischer. — The ribs are 

 smaller and more finely marked than in M. alauda. 



476. alauda (f. 134, 135, 158), Quoy. 



477. Deshayesii (f. 155, 018), Reeve. 



478. rustica (f. 143), Reeve. — The ribs are broad, rounded, 

 and distant. 



479. armillata (f. 496), Reeve. — Remarkable for the short- 

 ness of the whorls, the last being little more than half as 

 long as the spire. 



480. turricula (f. 647), A. Adams. 



481. oelata (f. 587), Reeve. — The last whorl narrow and 

 very cylindrical. 



482. Colinsoni (f. 621, 2), A. Adams? 



483. hastata (f. 620), Sowerby. — The name casta, having 

 been previously occupied for the well-known cylindrical 

 species, it is necessary to use another name for this species. 

 Mr. Adams, treating " Turricula " as a distinct genus, re- 

 peated an old specific name. 



484. subulata (f. 149, 150), Lamarck. 



485. mackosfira (f. 146), A. Adams.
