Show 1870.] MR. o. SALVIN O N T H E BIRDS O F VERAGUA. 191 62. LEISTES GUIANENSIS (Linn.) ; Scl. Cat. Am. B. p. 138. This common South-American species has not hitherto been noticed in Central America. Arce's specimens differ in no way from Guiana and Bogota examples. 63. MOLOTHRUS ^ENEUS (Wagl.) ; Scl. Cat. Am. B.p. 135. Chitra ; Calobre. A Central-American species occurring in Costa Rica, but not yet noticed at Panama. 64. QUISCALUS MACRURUS, SW. 1 Calovevora; Calobre. Two males sent by Arce are smaller than Guatemalan specimens attributed to this species, but do not otherwise differ. They agree in dimensions with a specimen from Panama in our collection. Sturnella ludoviciana. Castillo ; Calovevora ; V. de Chiriqui. 65. CASSIDIX ORYZIVORA (Gm.) ; Scl. Cat. Am. B. p. 142. Calovevora ; Chitra ; Calobre. This common species has not yet been sent from Costa Rica. In Guatemala it is abundant in the lowland forests of Vera Paz in the vicinity of the clearings. 66. CYANOCORAX AFFINIS, V. Pelz.; Scl. Cat. Am. B. p. 145. Calobre; Bugaba. The only member of the Corvidse in Veragua and Panama. Its range does not extend to Costa Rica. Sclerurus mexicanus. Calovevora. This species, now found to inhabit portions of the southern continent as well as Mexico, will almost certainly occur in Costa Rica, where, however, its presence has not yet been discovered. 67. SYNALLAXIS ERYTHROPS, Scl. P. Z. S. 1860, p. 66; Lawr. Ann. Lye. N. Y. ix. p. 105. V. de Chiriqui. The four specimens forwarded by Arce all agree with one another, and with Sclater's type specimens, with which 1 have compared them. W e possess a specimen of Synallaxis from Costa Rica (Carmiol), which agrees accurately with Mr. Lawrence's description of his S. rufigenis (Ann. Lye. N. Y. ix. p. 105). The bird is in immature plumage, and may possibly turn out to be a young state of £. erythrops, though I hardly think so. Still the immature plumages of Synallaxis are so perplexing that I throw out this suggestion to induce a further examination should additional specimens come to hand. |
