approach the small race (minor Cherry) of Costa Rica. The 

 material does not, however, allow further discussion of the fact.

This series is of great interest because the colour of the 

 pileum displays such different shades in the different speci- 

 mens. In one of the males it is so dark, that one may feel 

 almost tempted to refer the specimen to the more southern, 

 dark-headed »striaticollis »-group, but there are all intergrada- 

 tions in the others to the same colour as the back. From this 

 the conclusion lies near at hand, that all the different races, 

 that have been described under the heads of »striaticollis» 

 and »olivaceus», only are subspecies of one and the same 

 species. The first of these appears to be the oldest specific 

 name, which originally was given to the darkheaded race of 

 Bolivia. The next with regard to the dark shades of the head 

 is the Peruvian poliocephalus. In which connection this one 

 stånds to hedereceus Bångs, appears rather doubtful, because 

 the just quoted author has not explained, by which character- 

 istics his new form is to be distinguished from poliocephalus. 

 It appears rather probable that a comparison of sufficient 

 material will prove, that poliocephalus and hederaceus merge 

 into each other. Thus a continuous series might be formed 

 from the most dark-headed southern striaticollis to the most 

 light-headed olivaceus in the north. 



The present specimens display a certain variation also 

 in another respect, viz. with regard to the length of the culmen, 

 which measures in three males from the same locality resp. 

 12,5, 13 and 15 mm.
