This species is about the size of the Common Partridge. The 
specimens from which the above descriptions were taken are in the 
British Museum, to which they were presented by Lord Stewart ; 
they are said to he from Brazil. 
Specimens of new species of the genera Trochus and Turbo were 
also exhibited, and were accompanied by the following descriptions 
by Lovell Reeve, Esq. 
Genus Trocuus. 
Trocuus asteriscus. Troch. testd obeso-conicd, viridescente, an- 
Sractuum margine squamoso-stellatd, squamis, grandibus cavis, in- 
fimd facie eximié serratd, serris linearibus, parallelis, circulatim 
dispositis ; umbilico tecto, basi roseo-tinctd.

Hab. ——? 
This shell has the base of the columella stained with rose-colour, 
like the Trochus rhodostoma, Lamarck ; there is no danger, however, 
of confounding it with that species ; the under surface of the Trochus 
asteriscus is most elegantly serrated, the serree ranging round with 
peculiar regularity ; and the periphery of each whorl extends into 
large hollow spouted scales. The shell figured in ‘ Conch. Syst.,’ at 
fig. 5 of the same plate, under the name of Trochus pileolum, appears, 
by a figure subsequently published in Delessert’s ‘ Recueil de Co- 
quilles,’ to be the Trochus fimbriatus of Lamarck. 
a 
Trocuus cemmosus. Troch. testd parvd, conoided, luteo et violaceo 
vivide variegatd ; anfractibus leviter convewxis, superficie ubique 
granulatd, granulis obtusis, quasi gemmosis ; infimd facie similiter 
ornatd. 
Reeve, Conch. Syst., vol. ii. pl. 218. f. 9. 
Alt. 2; diam. 3 poll. 
Hab. ? Mus. Stainforth. 
This is a most lovely shell to look upon; it is richly variegated 
with violet and yellow, and the surface being obtusely granulated, 
gives it the appearance of being studded with gems. 
Trocuus Hantryanus. Troch. testd acute conicd, viridi, levis- 
simé nodulosa ; anfractibus planiusculis, peripherid ultimi acutd ; 
infimd facie roseo-tinctd, minutissimé serratd, serris regularibus, 
seriatim dispositis, umbilico parvo.
