This is the ordinary " Bogota" form, and is, we suppose, that figured by Gray and Mitchell, as above quoted; but no description is given. It is much nearer to the last than to the succeeding, having no greenish tinge to the blue. But the throat is lighter, tbe head paler, and the upper surface generally not quite so dark. Mr. Wyatt's skin from Pamplona belongs strictly to this form. y. QUINDIUNA. Of this form Mr. T. K. Salmon has lately sent us many examples from the Cordillera of Quindiu. The forehead is of a more intense blue than in the Bogota bird ; and this colour is continued over the head and shoulders. The lower back, wings, tail and belly below are of a more greenish blue ; but the throat within the black collar is of nearly the same tint as in 3. P.S.-Since this paper was written we have received from Mr. Lawrence a separate copy of his paper entitled " Description of a new Species of Jay of the Genus Cyanocitta, and of a new Species of the Genus Cyanocoraxi'' read October 11th of last year before the Lyceum of Natural History of New York. So far as we can tell from Mr. Lawrence's description, his Cyanocitta pulchra, from Ecuador, there described, is a species with which we are not acquainted. But the Cyanocorax, for which the name C. ortoni is suggested (Ann. L. N . Y. xi. p. 166), is, in our opinion, none other than Cyanocorax mystacalis, Geoffr., of which name C. uroleucus, Heine, J. f. Orn. 1860, p. 115, is a synonym. Sclater's collection contains a skin of this species from Loxa in Ecuador, which agrees in every respect with Mr. Lawrence's description of his supposed new bird. The association of C. mystacalis with C. cayanus (by Bonaparte and others) is a great error, as may be seen by reference to the original types of the former now in the Paris Museum and Philadelphia Academy, both of which we have inspected, or even to the sufficiently accurate figure in the ' Magasin de Zoologie.' Whether C. bellus of Schlegel is really referable to C. mystacalis (as suggested, Ibis, 1868, p. Ill) is perhaps not quite certain; for, as pointed out by Mr. Lawrence, Schlegel describes the outer tail-feathers of his C. bellus as having their bases blue. An examination of the typical specimen will be necessary to decide this question; but it will, in our opinion, probably turn out to be the case that the assertion made in the ' Ibis' is correct. |
