CREEPING LOCUSTELLE. Locustella certhiola. Sylvia certhiola, Pal/. Le Beec-fin trapu. We beg leave to express our sincere thanks to Professor Lichtenstein, one of the Directors of the Royal Museum of Berlin, for the obliging manner in which he has entrusted to our care the original specimen of this rare bird, from which Pallas took his description, and which we are given to understand was mounted by that celebrated naturalist himself. In form and general colour, and doubtless in its habits, this species strictly belongs to the.genus Locustel/a, from the two other species of which it may be distinguished by its larger size, and by the greyish white termination of all its tail-feathers. Of its habits and manners no account has been recorded, and we only know that it is found in Southern Russia, where it appears to be very scarce. We may here remark, however, that the secluded habits of this race prevent their being observed unless they are very closely watched, and that by the eye of one accustomed to the investigation of the manners of birds in a state of nature. Feathers on the crown of the head, back of the neck, back and wing-coverts olive brown tinged with red, each feather being dark brown in the centre ; primaries and tail reddish brown, the latter tipped with greyish white ; throat white; stripe over the eye, sides of the head, and all the under surface buff, which becomes very pale on the breast and centre of the abdomen ; bill and feet light brown. The figure is of the natural size. > wae ~
