Show 190 MR. o. SALVIN ON THE BIRDS OF VERAGUA. [Mar. 24, whether the grounds for their separation are based upon sufficiently constant characters. From Mr. Lawrence's descriptions I gather that S. semicollaris has a white patch on each side of the neck, but no collar interrupting the uniform black of tbe chin, throat, and breast. 5. co/larii has a narrow white collar. 5. hicksi has the throat white and a collar uniting with it. S. fortipes has a white patch on each side cf the neck connected with a narrow collar, and thus differs from 5. semicollaris, but resembles S. collaris, with which it is not compared. Have we here really more than one variable species ? Vo/atinia jacarina. Chitra. Phonipara pusilla. Chitra. Cganospiza ciris. V. de Chiriqui. 58. CYANOSPIZA CYANEA (Linn.) ; Scl. Cat. Am.

CHRYSOMITRIS MEXICANA (SW.) ; Scl. Cat. Am. B. p. 124. This species ranges as far south as Panama (Scl. & Salv. P. Z. S. 1864, p. 353). The presence of C. columbiana, Lafr. (Lawr. Ann. Lye. N. Y. ix. p. 103) in Costa Rica is at present hypothetical. Ocyalus waqlcri. Chitra ; Calobre. 61. OSTINOPS CRISTATUS. Bugaba.
