194 MR. o. SALVIN ON THE BIRDS OF VERAGUA. [Mar. 21, some other members of the genus, as its name would imply, but even exceeds Bogota specimens of X. trochilirostris in our collection. The sexes, as determined by Arce, are quite alike. 82. OXYRHYNCHUS FRATER, Scl. & Salv. Ex. Orn. p. 131, t. 66. Calovevora ; Chitra. For a full account of this bird see our plate, I. c. Cymbilanius lineatus. Calovevora ; Calobre ; Mina de Chorcha. 83. THAMNOPHILUS IMMACULATUS, Lafr.; Salv. Ibis, 1870, p. 114. Calobre; Calovevora ; V. de Chiriqui. This species, of which Arce has sent both sexes, is also found in Costa Rica as well as in New Granada. It has not yet been noticed at Panama. 84. THAMNOPHILUS PUNCTATUS, Cab. J. f. Orn. 1861, p. 241. Mina de Chorcha, Bugaba, V. de Chiriqui. Originally described from Costa Rica, whence we have a single skin collected by Carmiol. The bird appears to be commoner in the district of Chiriqui, where Arce has obtained us a good supply of specimens. 85. THAMNOPHILUS RADIATUS, Vieill. Chitra ; Calovevora. Specimens from these localities agree with others from Panama ascribed to this species (see Scl. & Salv. P. Z. S. 1864, p. 355.). Thamnophilus affinis, Cab. T. doliatus, Scl. P. Z. S. 1856, p. 141. Bugaba. Specimens agreeing with this northern race having been sent from the district of Chiriqui, it follows that Bridges's specimens must also he ascribed to the same race. Thamnophilus bridgesi. Mina de Chorcha ; Bugaba. On reaching the Chiriqui district, the original habitat of this species, Arce at once obtained specimens. The same species also occurs in Costa Rica (Lawr. Ann. Lye. N. Y. ix. p. 107). 86. THAMNISTES ANABATINUS, Scl. & Salv. P. Z. S. I860, p. 299. Calovevora; Bugaba. Arce's determination of the sexes of this species confirms the view originally taken, that the individuals wh-ch possessed the ferruginous dorsal spot were males. Costa-Rican and Veraguan specimens agree with the types from Vera Paz. Dysithamnus semicinereus. Calovevora; Chitra ; Calobre; V. de Chiriqui.
