ins almost innumerable, there is aconsiderable amount of uniformity in its forms of animal life.From the Ladrone islands on tlie west, to the Marquesas on thecast, a distance of more than 5,000 miles, the same characteristicgenera of birds prevail; and this is the only class of animals onwhich we can depend, mammalia being quite absent, and reptilesvery scarce. The Sandwich Islands, however, form an exceptionto this uniformity; and, as far as we yet know, they are sopeculiar that they ought, perhaps, to form a separate sub-region.Tlioy arc, liowever, geographically a part of Polynesia; and amore careful investigation of their natural history may showmore points of agieement with the other islands. It is thereforea matter of convenience, at present, to keep them in the Poly-nesian sub-region, wliich may be divided into Polynesia pro))erand the Sandwich Islands.
