I am not satisfied that it is not found in other countries further east ; at the same time I much question whether the assertion of its being a native of Amoorland, Kamtschatka, and even China be correct; indeed I feel assured that the bird is not found therein, but that the species mistaken for it is probably the one I have called Chelidon Cashmiriensis, which may also be the bird Mr. Jerdon speaks of in his ‘Birds of India,’ under the name of English House-Martin, as having been found by him in small numbers, in one locality, on the Neilgherries. It may, however, extend its range throughout Persia, to the confines of India; but we have no direct evidence of the fact. The Rev. H. B. Tristram states that “it is the last of the Swallow tribe to return to Palestine, where it appears in great numbers about April 5th, and breeds in colonies on the sheltered faces of cliffs in the valleys of northern Galilee.” ‘The chief differences between C. Cashmiriensis and C. urbica is the smaller size of the former, and particularly the darker colours of its axillary feathers. “The ease and rapidity of its flight, however marvellous, excites no astonishment, as we are daily in the habit of witnessing them,” says Macgillivray ; “but a true lover of nature can, nevertheless, contemplate its airy windings for hours with delight. The evolutions of this species resemble, in all respects, those of the Swallow ; but its flight is perhaps somewhat less rapid, although it is certainly very difficult to decide with accuracy in a comparison of this kind. Its sweeps and curves, however, seem to me less bold, or, rather, less extended ; but its dexterity is equally remarkable. The influence of the weather on the flight of insects causes it to observe the same selection of places that they do; so that, in calm and cloudless days it flies more in the open air, in windy weather more in the shelter of hedges and walls, and in damp evenings it skims over the grass and corn.” To give some idea of the numbers of insects which these birds capture to feed their young, besides those taken for their own support, I may mention that one of Macgillivray’s correspondents informed him that a pair of Martins began to feed their young ones, four in number, at twenty-five minutes after four o’clock in the morning ; and at ten minutes after eight in the evening, when they ceased from their labours, they had oe : ; ’ iG ee a 307 times: this was on a bright sunny day ; on a subsequent dull rainy one, they only .
