Mr. Boardman writes me that he has several times collected Ravens’ eggs at Grand Menan, but always found the nest a hard one to take, as they usually build it under some high cliff. They make a very large and bulky nest, and, where not disturbed, use it several years in succession. They also breed very early. He once took a nest with eight eggs on the 10th of April, when the snow all around was quite deep. This was sent to the Smithsonian Institution. Its contents nearly filled a bushel basket. He does not regard the Ravens as migratory. Though they are apparently more numerous in winter than in summer, this is probably because they forsake the woods and come about the open fields and the banks of rivers for dead fish, and thus are more noticed. They are very shy, sagacious, and vigilant, so much so that it is almost impossible for one to get a shot at them. Crows avoid them, and the two are never seen together. The farmers of Grand Menan accuse them of pecking the eyes out of young lambs, and always try to destroy them, and they grow less and less numerous every year. The Ravens, he adds, appear to be on good terms with the Duck Hawks, as he has known a nest of the former within a few rods of one of the latter. An egg of this species, from Anderson River, measures 1.96 inches in length by 1.32 in breadth. Two from Grand Menan measure, one 2.05 inches by 1.30, the other 1.95 by 1.25. The ground-color of two of these is a soiled sea-green, that of the third is a light bluish-green. This is more sparingly marked with dots, blotches, and cloudings of faint purple and purplish-brown, chiefly at the larger end. The others are marked over the entire egg with blotches of varying size and depth of coloring, of a deep purple-brown; some of the markings are not readily distinguishable from black. Corvus cryptoleucus, COUCH. WHITE-NECKED CROW. _Corvus cryptoleucus_, COUCH, Pr. A. N. Sc. VII, April, 1854, 66 (Tamaulipas, Mexico).—BAIRD, Birds N. Am. 1858, 565, pl. xxii.—COOPER, Orn. Cal. 1, 1870, 284. SP. CHAR. The fourth quill is longest; the third and fifth equal; the second longer than the sixth; the first about equal to the seventh. Glossy black, with violet reflections; feathers of neck all round, back, and breast, snow-white at the base. Length, about 21.00; wing, 14.00; tail, 8.50. Feathers of throat lanceolate; bristly feathers along the base of the bill covering it for nearly two thirds its length. HAB. Valley of Rio Grande and Gila. Abundant on the Llano Estacado, and at Eagle Pass, Texas (DRESSER, Ibis, 1865, 494). Colorado (AIKEN). In the white bases to the feathers of the neck, etc., there is a resemblance in this species to the _C. leucognaphalus_ of Porto Rico; but the latter has entirely different proportions, blended instead of lanceolate feathers on the throat, exceedingly short instead of unusually long nasal plumes, and many other differences, and is in every feature totally distinct.
