M. atronitens, Cab., of Guiana, is not the same, as supposed by Cassin, but a smaller species, of the same size as 31. bonariensis. 147. HYPOPYRRHUS PYRRHOGASTER (De Tarr.) ; Bp. Consp. p. 425. Envigado, Sta. Elena. (Mus. P. L. S. and S.-G.) Iris white. Eggs (no. 121) pale greenish grey, spotted and streaked with lilac and dark brown: axis 1*22, diam. *82. (See PlateXLIII. fig. 4.) " A restless bird, seldom seen alone, but in small parties of six or eight. In the breeding-season, however, its habits are solitary. The nest is composed of large dead leaves and sticks, and is placed loosely in the fork of a small tree."-T. K. S. 148. CASSIDIX ORYZIVORA (Linn.) ; Scl. Cat. A. B. p. 142. Concordia, Antioquia, Remedios. Iris white. Eggs (no. 152) white: axis 1*45 and 1*15, diam. *93 and *86. There is a remarkable difference in the size of the two eggs sent of this species. 149. CYANOCORAX INCAS (Bodd.) Xanthura yncas, Sharpe, Cat. B. iii. p. 129. Xanthura incas, Scl. Ibis, 1879, p. 87. Retiro, Concordia, Sta. Elena. (Mus. P. L. S. and S.-G.). Iris yellow. Mr. Salmon's skins have the head quite white, and belong to the typical form from Ecuador and Peru. Eggs (no. 120) greenish grey, thickly mottled with darker shades of the same colour : axis 1*15, diam. *85. " Has much the habits of the English Jay, being ever on the move and seldom silent, except when near its nest or when at mischief. It robs the Indian corn-fields before the grain is ripe, but at other times subsists on grubs and insects. The nest is made of sticks and roots, and is placed in a high bush. The number of eggs is four."-T. K. S. 150. CYANOCORAX AFFINIS, Pelzeln; Scl. Cat. A. B. p. 45; Sharpe, Cat. iii. p. 121. Cauca, Remedios. (Mus. S.-G.) Iris yellow. Eggs (no. 159) clay-brown, thickly spotted, especially at the larger end, with spots of several shades of yellowish brown: axis 1*35, diam. *97. "The nest is composed of sticks; and all I have seen have been placed with considerable skill in places difficult to find, generally a good way out on a branch. Though a noisy bird at all other times, it is usually quiet when near its nest."-T. K. S. |
