. Review of American birds in the Museum of the Smithsonian Instution. [microform]. Birds; Oiseaux. TEIIETU18TI8. 233 l«t anil longest primarieo, .CO ; length of bill from forehead, .60, from nostril, .37; along gap*), .HI ; tarsus, .80 ; middlu toe and claw, .UG ; claw alone, .20; hinil toe and claw, .46 ; claw alone, .21. This beautiful and hitherto undcscribod species is quite similar to G. vcnuHtuH in appearance, but (litters in a much longer, broader, and more rountler tail. The wing is much graduated ; the 4th and 5th ({iiilis nearly equal; the 3d a little shorter; the 2d about e(|uiil to the 7th; the Ist shorter than the secondaries. The principal (lifftTi'iice in coloration consists in the absence of the black pectoral colhir (although a few concealed spots may be considered as repre- senting it) ; in the pure white of the sides of the breast, instead of plumbeous; in the narrow whitish bands across the wings; the greater amount of white on the tail, etc. From pelzelnii it is guished by the plumbeous crown and white tips of the tail feathers. Tiiis bird is one of a number of new species discovered, during the past winter, by Col. Grayson, on one of the Three Marias, a group of Islands off" the coast of Mexico, about eighty miles from San IMas ; and I cannot more appropriately dedicate it than to Mrs. Grayson, to whose encouragement Col. Grayson owes so much of the persistency and success with which he has prosecuted the study of the ornithology of California and western Mexico. Sinlth- Sa. Collec- tiir'8 No. Sex and Atra. Locality.
