352 APPENDIX. 



and summer, in almost daily excursions, with con- 

 stant 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 en- 

 tirely distinct classes, and must therefore be natives

 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, Patrohus and other Carabides, find a 

 cool abode among the stones on the banks of the 

 ice-cold brooks which fall from the snowy summits

 kinds of Xylophagi and some Cerambycidts ; the 

 old mossy trunks of fallen trees afford hiding- 

 places for several kinds of Carabides, as two 

 Cijchrus, Leistus, Platysma; and for Nitidula, Scapki- 

 dium, 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, 

 2ind-Silis; besides Elater of eight kinds, and a ninth 

 living under stones. 



The small standing waters, formed by single 

 cavities, are proportion ably rich in water-beetles, 

 among which is found a Dyticus of the form of
