On the Habits of the Volutes. Bj Dr. R. 0. Cunning- 

 ham. 



" In the April number of the ' Annals and IMagazine of Nat- 

 ural History,' which I received not long since, I find at p. 310 

 a note by you on the habits of Volutes, in which you remark 

 that they are rarely collected with their animals, except when 

 they are accidentally thrown ashore after a storm, and that this 

 is owing to their sand-burrowing propensities. This I have 

 found to be the case as regards the species of the genus inhabi- 

 ting the Strait of Magellan, During the first season I spent in 

 that region, I only succeeded in obtaining two live specimens 

 of Voluta magellanica, till the occurrence of a violent easterly 

 gale caused numbers to be thrown on the beach in the neighbor- 

 hood of the Chilian settlement at Punta Arena. That they only 

 existed in comparatively shallow water I considered sufiiciently 

 proved by the fact that I never succeeded in dredging any, 

 though they were evidently far from rare, judging from the num- 

 bers of dead shells to be picked up in most localities in the east- 

 ern part of the Strait. I obtained a second species of Volute, 

 of which there is no specimen in the collection of Magellanic 

 shells in the Museum at Santiago, at low water at Cape Posses-
