I have named the sh.e.l.l after my s.h.i.+pmate and friend, Lieutenant Thomas Graves, whose zeal and a.s.siduity in a.s.sisting and increasing my collections of Natural History was as unwearied as the alacrity and ability which he displayed in the primary and more important objects of the voyage, of which, in his Majesty's s.h.i.+p Adventure, he filled the appointment of a.s.sistant surveyor. To Lieutenant Graves I am princ.i.p.ally indebted for my land-sh.e.l.ls, and I therefore take the opportunity of recording the valuable a.s.sistance he rendered me during the whole period of his serving under my command.

The body-whorl of the older specimens of this sh.e.l.l is rather roughly striated or wrinkled, the last but one slightly so, and the remaining whorls are quite smooth. The colour is whitish, with {553} purple spots more or less obsolete: the old specimens are sometimes of a dull yellowish white. A specimen is deposited in the British Museum.
The young sh.e.l.ls of this species are of a whitish brown, with darker coloured striae. They are very fragile and semi-transparent.

_Habitat ad oras Americae meridionalis_ (Chile). _Mus. Brit., nost., Brod., Geo. Sowerby, &c._
Soon after the return of the expedition, my friend Mr. Broderip, to whose inspection Lieutenant Graves had submitted his collection, observing symptoms of life in some of the sh.e.l.ls of this species, took means for reviving the inhabitants from their dormant state, and succeeded. After they had protruded their bodies, they were placed upon some green leaves, which they fastened upon and ate greedily. These animals had been in this state for seventeen or eighteen months, and five months subsequently another was found alive in my collection, so that this last had been nearly two years {554} dormant. The sh.e.l.ls were all sent to Mr. Loddige's nursery, where they lived for eight months, when they unfortunately all died within a few days of each other. Soon after the sh.e.l.ls were first deposited at Mr.
Loddige's, one got away, and escaped detection for several months, until it was at last discovered in a state of hybernation; it was removed to the place where the others were kept, when it died also. The upper surface of the animal when in health is variegated with ruddy spots and streaks on an ash-coloured ground.
