J. f. Orn. 1860, p. 415. V. de Chiriqui. This appears to be a rare species, as none of the collectors of the Smithsonian Institution have yet met with it. When in Costa Rica, Arce was fortunate enough to obtain two specimens in the Volcan de Cartago ; these are the only others I have seen. With the exception of the tarsi and toes being rather stronger, Pezopetes does not differ from Buarremon, in which genus it might be very properly included. Saltator magno'ides. Calovevora; Chitra ; Mina de Chorcha ; Bugaba ; V. de Chiriqui. Saltator isthmicus. Chitra. 55. HEDYMELES LUDOVICIANUS. V. de Chiriqui. 56. PHEUCTICUS TIBIALIS, Lawr. Ann. Lye. N. Y. viii. p. 478.

S. schistacea, Lawr. Ann. Lye. N. Y. viii. p. 10. Bugaba. Agrees with specimens in Sclater's collection from Cayenne, Venezuela, and Bogota. Spermophila semicollaris. Bugaba. A specimen from this locality is without the white collar across the throat; others, from Calovevora, Chitra, and Mina de Chorcha, have this collar, but to a variable extent: I suppose these last should be called 5. collaris, Lawr. One of the Chitra specimens has the rump quite white. Judging from seven specimens before me, and seeing that the amount of white forming the collaris variable, I find great difficulty in assigning my specimens to the species described by Mr. Lawrence as Spermophila hicksi, S. semicollaris, S. collaris, and S. fortipes, ail of which are found on the Panama Railway-line or at Chiriqui. Concise diagnostic characters of these four birds would be useful, and would afford a better opportunity of judging PROC. ZOOL. Soc-1870, No. XIV. |
