112 THE DISPERSAL OF SHELLS. 



BULLMUS ROSACEUS.— Four individuals of a large 

 Bulimus from Valparaiso, as related by Sir C. Lyell in 

 the " Principles," were brought to England by Lieu- 

 tenant Graves, who accompanied Captain King in his 

 expedition to the Straits of Magellan ; they had been 

 " packed up in a box, and enveloped in cotton, two for 

 a space of thirteen, one for seventeen, and a fourth for 

 upwards of twenty months," but, when exposed by Mr. 

 Broderip to the warmth of a fire in London, and provided 

 with tepid water, Lyell saw them revive and feed 

 greedily on lettuce-leaves. B. rosaceus seems to be the 

 species referred to, of which Captain King, in a paper 

 on the Mollusca, etc., collected by the ^' officers of H. M.S. 

 Adventure and Beagle employed between the years 1826 

 and 1830 in surveying the southern coasts of South 

 America including the Straits of Magalhaens and 

 the coast of Tierra del Fuego," gives the following 

 note : 



" 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 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 dormant. 

 These shells were all sent to Mr. Loddige's nursery,
