Note 13 — Chapter XXXV

I am indebted to Dr. William Stimpson for a careful examination and comparison of this collection, the results of which were published by him in the "Proceedings" of the Academy of Natural Sciences of Philadelphia, for May, 1863. The collection contains little that is wholly new; but, as Dr. Stimpson has remarked, "They possess great interest from having been found, in great part, in localities much nearer the Pole than any previous expeditions have succeeded in reaching on the American side of the Arctic Circle. They include some species hitherto found only on the European side; and, we may add, the number of species collected by Dr. Hayes is greater than that brought back by any single expedition which has yet visited those seas, as far as can be judged by published accounts." The collection embraces, of Crustacea, 22 species; Annelida, 18 species; Mollusca, 21 species; Echinodermata, 7 species; Acalephæ, 1 specie; and, besides these, a considerable number of Nudibranchiata, Actiniæ, etc., which cannot well be determined from alcoholic specimens.
