The young shells of this species are of a whitish brown, with darker coloured strice. They are very fragile and semi-trans- parent. 32. BuLiNus soRDiDus.— No. 803 MSS.

Soon after the return of the expedition, my friend Mr. Broderip, to whose inspection Lieutenant Graves had submitted his collec- tion, observing symptoms of life in some of the shells 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 * Whilst this sheet was printing, the September number of the Annalcs des Sciences made its appearance in England, containing a description of the above shell by M. Sander Rang, accompanied by an excellent figure (Annales des Sciences Naturelles, September 1831, p. 55, pi. 3, f. 1). It is there named Helix multicolor. In my description I have considered it to be a Bulinus, but its specific name has been altered to that given to it by M. Rang.
