The specimen figured in Am. Ex. Ex. is immature That by 

 Wood 1 mark doubtful. I class exaratus, Pse., as a synonym, 

 contrary to the opinion of the. late Mr. Cuming. Although M. 

 Deshayes, in An. sans Vert., refers to the fig. 56a in Kiener, in 

 illustration of deformis, he cites it in his work on Bourbon shells 

 as P. exaratus, Pse., without reference to Lamarck. If the 

 figure of Kiener is a synonym of deformis, exaratus is also.

Vexilla (s. g. Usilla) fusco-nigra, Pse. 



1860. Proc. Zool. Soc. London, p. 141. 



H. Adams, in P. Z. S. London, proposed the above subgenus 

 for this species. To it should be added Purpura leucostoma, 

 Desh., inhabiting the Island of Bourbon, and also Planaxis cin- 

 gulata, Gld., described from Japan. The latter is closely allied 

 to fuseonigra, Pse. 



Ricinula hystrix, Linn. 



The variety of B. clathrata, figured by Reeve in Conch. Icon., 

 pi. 2, fig. 9a, is a variation of the above species. There occurs, 

 however, at the same locality, a similar variety of R. clathrata.

The elegans varies from its type in the same manner as lobata 

 from digitata, the line surrounding the aperture being of a 

 purple instead of a yellow color. The sculpture is precisely the
