They comprise a part of the shells and alcoholic inollusca which I col- 

 lected during my travels in the East Indian Archipelago ; also four skel- 

 etons of the sea otter from Alaska. The alcoholic collection contains 

 most of the species found on the shores of Amboyna and the three isl- 

 ands adjacent, in sufficient numbers to afford ample material for study- 

 ing their anatomy. It was chiefly to obtain such specimens and to 

 ascertain beyond a doubt their precise habitat, that I travelled to the 

 Molluccas. Eespectfully yours,
