RENDAHL, BIRDS FROM THE PEARL ISLANDS. 53 



Count Berlepsch in his Revision der Tanagriden (1. c.) 

 referred the San Miguel birds to Tanagra cana diaconus Less. 

 indicating, however, the distinctness of this Central American 

 subspecies as doubtful, and saying also (p. 1136), that from 

 two specimens from San Miguel I. (Bångs' Collection) he 

 could detect no differences when compared with specimens 

 from Bogota, Cali, and Venezuela. 



In consequence of what is quoted above, I find no real 

 grounds for regarding the Pearl Islands birds as belonging to 

 a separate subspecies but follow the arrangement of Berlepsch 

 in referring them to T. cana diaconus of the main. Further 

 researches about this question are, however, greatly to be 

 desired.

The present young male specimen is in a transitory plum- 

 age between that of adult male and female. The color is 

 mainly like that of the male, but paler and intermixed with 

 yellomsh feathers and with most of upper tailcoverts yellowish 

 olive towards tip; the wings however, are of the same color 

 as in the female except the most dorsal of the wingcoverts and 

 some proximal tertials, which are dull red as in adult male 

 Of the rectrices the outermost two pairs are like those of the 

 female, the middle ones red, but duller than in the adult male.
