W e have now both sexes of this fine species, of which the male only appears to have been previously known. The female I now describe as follows :- Schistaceo-nigra, a/is caudaque paulo obscurioribus et extus, nisi in rectricibus quatuor mediis, albo transfasciatis: ventre et crisso coccineis. 121. TROGON PUELLA, Gould. V. de Chiriqui. Though found in Costa Rica, this is the most southern locality yet recorded for the occurrence of this species. Trogon aurantiiventris. Calovevora; Castillo. The range of this species, which is abundant in the eastern parts of Veragua (Calovevora & c ) , quite overlaps that of T. puella, a few individuals occurring as far north as Vera Paz. The two species are only to be distinguished by one having the underparts red, the other orange-yellow. Trogon atricollis. Calovevora; Chitra ; Bugaba ; V. de Chiriqui. Trogon clathratus. Calovevora. The range of this species is now shown to extend to Costa Rica (Lawr. Ann. Lye. N. Y. ix. p. 119). Trogon massena. Bugaba ; V. de Chiriqui. Pharomacrus mocinno. Pharomacrus costaricensis, Cab. J. f. Orn. 1869, p. 313. Calobre ; Calovevora ; V. de Chiriqui. In an editorial note to Dr. v. Frantzius's paper on Costa-Rica birds, Dr. Cabanis proposed the separation of the Costa-Rican from the Guatemalan Quezal, and gave the former the name P. costaricensis. One of the distinctions pointed out consists in the number of elongated tail-coverts, the Guatemalan bird having, as stated, six, the Costa-Rican four. The former, too, is said to be of a more golden tinge on the upperside in certain lights, the latter being rather bluish. There can be little doubt that the tail-coverts attain a greater length and breadth in the Guatemalan bird ; but the number which exceed the length of the rectrices is never more than four, though another pair of elongated feathers sometimes reach as far as the extremity of the tail. The length of these plumes varies much |
