Mr. Robert Damar, of Weymouth, England, a well-known naturalist and geologist, died May 4th, in his seventy-fifth year. He was an extensive traveler and assiduous collector. Among the collections he made were a series of fossil fishes from the cretaceous beds of the Lebanon, Syria; the most complete specimen of the extinct Steller's sea-cow, from Behring Island; and a series, called complete, of the fishes of the Caspian Sea.

He was the author of a work on the "Geology of Weymouth and the Island of Portland." He was contemplating, at the time of his death, another trip to Siberia, to procure an entire mammoth's skeleton.
