 rounded, inflated, smooth, transversely obsoletely 

 gi'ooved, reticulately striated towards the apex ; colu- 

 mella smoothly plicated and conspicuously granose,

Hab. Barbados. 



The first authentic illustration of this species occurs in 

 Shaw's Naturalist's Miscellany, 1789, with the name Biic- 

 cimmi inflatum. Ten years subsequently an equally cha- 

 racteristic figure of it was published by Chemnitz in his 

 last volume of the Conchylien Cabinet under the title Buc- 

 cinuni cassideum tesselMum. These, however, were over- 

 looked by Bruguiere and Lamarck, who introduced the 

 species with the name granulosa, and referred for iUustratiou 

 to Martini's figm-es, Conch. Cab. v. 2. f. 344—5 and 350- 

 52, which also comprehend the C. ubbremata and saburon. 

 Kiener, following in the steps of his predecessors in 

 adopting the name granulosa, added much to the con- 

 fusion by representing the C. recurvirostrum to be the young 

 of it, and that both were merely varieties of the C. sulcosa 

 of the Mediterranean, arising out of differences of age or 

 sex. It does not appear that this crotchet of M. Kiener's 

 was noticed in the new edition of Lamarck, and M.Deshayes 

 errs in stating that the figm'es above alluded to in Martini, 

 " can only be referred to this species." The shell Fig. 

 344-5 is without doubt a C. IMata, though presenting the 

 unusual feature of a strong lateral varix, but fig. 350, is 

 a variety of C. saburon, distinguished by the dark spots 

 behind the reflected lip, and the shell, Fig. 351 — 3 is a 

 pale variety of Lamarck's C. abbreviata. 



The coronated variety of C. inflatum is very uniform 

 and I am not aware that it exceeds the size of the specimen 

 here figm'ed.
