 of a dull yellowish white. A specimen is deposited in the British

 darker coloured stricB. They are very fragile and semi-trans- 

 parent.

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 Annales 

 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 Helioc multicolor. In my description I have 

 considered it to be a Bulinusy but its specific name has been altered to 

 that given to it by M. Rang.
