Of _Zoophytes_, some presented themselves of the genera _Antipathes_, _Millepora_; _Cellaria_, _Flustra_ two species, _Melobesia_, _Retepora_, _Acamarchis_, _Lafoea_, _Aglaophenia_, _Dynamena_ fives species, _Clytia_ four species, and _Folliculina_, two species. The _Antipathes_ consists of a simple stem resembling wood, which grows to the length of ten feet: it grows at a great depth in the open bay, and is often accidentally drawn up in fishing. Although of all insects of this island the beetle is the most numerous, yet during the whole spring and summer, in almost daily excursions, with constant fine weather, only one hundred and six kinds were found. On the whole, it may be observed, that none among them belong to any of the species which have been hitherto considered as peculiar to America; yet there are some of them which form entirely distinct classes, and must therefore be natives of the north-west coast of America. The result of close examination was, that none of those found here are to be met with either in the north of Asia or in Europe, and only seven species are to be found even in Unalashka. The Fauna is adapted to the climate and the soil; _Nebria_, _Patrobus_ and other Carabides, find a cool abode among the stones on the banks of the ice-cold brooks which fall from the snowy summits of the mountains; in the fir-woods, live several kinds of _Xylophagi_ and some _Cerambycides_; the old mossy trunks of fallen trees afford hiding-places for several kinds of Carabides, as two _Cychrus_, _Leistus_, _Platysma_; and for _Nitidula_, _Scaphidium_, _Agyrtes_, and _Boros_. On the skirts of the woods, shrubs and tall plants nourish some insects belonging to various families; as two _Homalisus_, _Omalium_, and _Anthophagus_, _Anaspis_, _Cantharis_, and _Silis_; besides _Elater_ of eight kinds, and a ninth living under stones.
