margin reflexed and thickened, unjbilicus very wide and spi- 

 rally dentate. 



Long Bay, rare. Eev. H. D. Atkinson. This shell is 

 nacreous within, and very near in form to L. discoidea Eeeve. 

 The nodse on the upper carina become little raised hollow 

 rounded squamae on the second whorl. 



MoxiLEA ROSEA. U.S. M. t. miiiuta, turbinata, late umbilicata, rosea, 

 maculis aJbis variegata ; anfractibus 4, 1'otundatis, striis albis viagnis et 

 jjarvls alternantibus cinctis ; apertura Integra, rotundata ; lahro pro- 

 ducto ; labio shnplici ; margine umbilici callo inconspicuo, albo, corrugato 

 instructo. Diam. 3. 



M. shell minute, turbinate, widely umbilicate, rose color, 

 variegated with white spots, whorls 4, rounded, encircled with 

 white alternating large and small strise ; aperture entire, 

 rounded; outer lip produced; inner lip simple; vimbilical 

 margin furnished with a somewhat inconspicuous white cor- 

 rugated umbilicus. 



This small shell is of intense carmine color in some speci- 

 mens. The outer lip is produced very much from the suture 

 so as to give the aperture a sunken appearance. The callosity 

 at the umbilicus is only perceptable under the lens in very 

 good specimens. 



GiBBULA DEPRESSA. U.S. 0. t. depresso-orhiculata, fidvo-purpurea 

 lugubre tincta ; umbilicata, late sulcata, sulcis transversim. striatis; an- 

 fraciibus 5, depressls ; ultimo anfracta permagno, cingulis sex subelevatis, 

 transversis, aliquando tessellatis insigno ; apertura obliqud subquadrata, 

 intus lirata, rosed viridique splendidd irridescente, labro tenui ; labia sub- 

 rejlezo. Diam. 10 mill. 



G. shell depressedly orbiculate, lugubriously-painted fulvous 

 brown and purple, umbilicate, widely sulcate, sulci transversely 

 striate ; whorls 5, depressed, last whorl, which is much larger, 

 distinguished by 6 transverse sub-elevated, and sometimes 

 tessellated belts ; aperture obliquely sub-quadrate, lirate 

 within, and splendidly iridescent with rose and dark green; 

 outer lip thin ; inner lip sub-reflexed. 



Adventure Bay, common. This shell is always more or less 

 encrusted with Polyzoa (Membranipora and Cellepora). It 

 might easily be mistaken for young shells of Trocltocochlea 

 striolata. Its depressed, almost angular, form and interior 

 iridescense, render it easily recognised.
