Picolaptes affinis, originally described by Lafresnaye from a Mexican specimen in the 

 collection of Mons. C. Brelay i, is now known to have a wide range over the highlands 

 of Mexico and Central America from the State of Vera Cruz to the mountains of Costa 

 Eica and Chiriqui. It also occurs on the uplands of the intervening country wherever 

 the mountains attain a sufficient elevation, 4000 feet being about the lower limit of its 

 vertical range. We note no appreciable variation in specimens from many points of its 

 wide range, notwithstanding that this range must be interrupted in several places. In 

 the lowlands of the same countries where P. affinis occurs, another species {P. com- 

 pressus) takes its place. From that species it may readily be distinguished by the spots 

 on the head being much shorter and bounded outwardly by black, and the streaks on 

 the neck and upper back are not nearly so well" defined ; the marks, too, of the under 

 surface are much more definite. The bill, too, is darker. 



P. affinis is not uncommon in the oak-forests of the volcanoes of Guatemala at an 

 altitude of from 6000 to 8000 feet above the sea.
