Ober’s Researches in the West Indies.—We are glad to hear 
that Mr. F. Ober, the collector for the Smithsonian Insti- 
tution, left New York early last month again for the West 
Indies, to continue his researches into the fauna of the 
various islands, in which he has already made such notable 
discoveries.
