Cordillera de Tole. 



A full description of this species will be found in the ' Ibis,' as 

 referred to above. In coloration this Dipper more nearl}^ approaches 

 North American specimens of C. mexicanns than Mexican, which 

 seem to be always darker. (See Baird's ' Rev. Am, B.' p. GO.) 



Troglodytid^.

Santa Fc and Santiago de Veragua. 



Two specimens sent b}^ Arce agree accurately with one another, 

 the species forming a distinct race from the northern M. philomela, 

 Salvin, P. Z. S. 1861, p. 202.

Microceradus leucostictus, Sclater & Salvin, P. Z. S. 1864, p. 345. 



Santa Fe, Veragua. 



This species seems to enjoy an uninterrupted range from Cayenne, 

 Ecuador, and New Granada to Mexico. I am quite unable to fiud 

 constant characters to separate specimens from the latter country 

 and Gruatemala from those obtained from more southern localities.

Santa Fe and Santiago de Veragua. 



This species has before been noticed on the Isthmus of Panama 

 (Lawr. Ann. N. Y. Lye. vii. p. 320). 



— 12. Thryothorus thoracicus, Salvin, P. Z. S. 1864, p. 580. 

 Santiago de Veragua. 



Three specimens from this locality differ in no way from the typical 

 Costa Rican examples. This species, lil-ce many others hitlierto con- 

 sidered purely Costa Rican, extends as far south as the termination 

 of the higher mountains of that conntrj', and tends to show that the 

 real boundary of the Costa Rican fauna must be sought here.

Thryophilus castaneuSy Baird, Rev. Am. B. p. 133. 

 Santiago de Veragua. 



This species has hitherto been only recorded from the Isthmus of 

 Panama.
