1870.] MR. O. SALVIN ON THE BIRDS OF 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. Arcé’s specimens differ in no way from 
Guiana and Bogota examples. 
63. MoLorurus &NeEvs (Wagl.) ; Scl. Cat. Am. B. p. 135. 
Chitra ; Calobre. 
A Central-American species occurring in Costa Rica, but not yet 
noticed at Panama. 
64. QuiscaALUS MACRURUS, Sw. ? 
Calovevora ; Calobre. 
Two males sent by Arcé 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. Cassiprx oryzrvora (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 Corvidee 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 con- 
tinent 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. 8. 1860, p. 66; Lawr. 
Ann. Lye. N. Y. ix. p. 105. 
V. de Chiriqui. 
The four specimens forwarded by Arcé all agree with one another, 
and with Sclater’s type specimens, with which 1 have compared them. 
We possess a specimen of Synallaxis from Costa Rica (Carmiol), 
which agrees accurately with Mr. Lawrence’s description of his 8, 
rufigenis (Ann. Lyc. N. Y. ix. p. 105). The bird is in immature 
plumage, and may possibly turn out to be a young state of S. ery- 
throps, though I hardly think so. Still the immature plumages of 
Synailaxis are so perplexing that I throw out this suggestion to 
pesace a further examination should additional specimens come to 
and.
