The land flora and fauna of Jamaica are stated on good authority to be the richest of the Antilles, while the coral reefs and marine fauna, although possibly

The Tortugas reefs, while not so rich in corals, are richer in fishes and invertebrates than are those of the Bahamas and probably of other West Indian Islands. The nearness of the Pourtales plateau would give the station an enviable opportunity for deep-sea dredging, while the remarkable purity of the ocean water surrounding the Tortugas would provide the laboratory with an almost unique advantage in the rearing of larvæ, and prosecution of physiological work.
