39. Centurus aurifrons hofTmanni (Caban.). 



The common Woodpecker of Costa Eica. Found everywhere except 

 on the more elevated monu tains. Iris white. 

 Two specimens. 

 No. 156. 5 ad. March 31. 

 No. 197. $ juv. April 16. 



40. Momotus lessoni Less. 



Not so common on the coast as in the interior. In the former locality 

 it seems to prefer the thick woods, while in the latter it Is often seen in 

 the more open fields. Generally a silent bird, but not shy. 



One specimen. 



No. 320. $ ad. May 5. 



41. Eumomota superciliaris (Sw. ). 



This exquisitely-colored Motmot is common throughout the coast re- 

 gion, where it bears the rather insulting name of " Bobo" (stupid). The 

 natives account for this name by saying that the bird hasn't sufficient 

 sense to tly away at the approach of the hunter. In truth it seems to 

 be quite fearless, and seldom disturbs itself on account of human prox- 

 imity. Although a very silent bird (I never heard its voice), its peculiar 

 spatulate tail-feathers are apt to attract attention. It seems to be soli- 

 tary in its habits, and not very industrious, as it is most often seen 

 sittiDg on a limb not far from the ground apparently engaged in deep 

 meditation, from which it is not aroused by the presence of the collector. 

 Iris brown. 



Three specimens. 



No. 199. $ ad. April 16. 



No. 207. S ad. April 17. 



No. 288. S ad. April 29. 



42. Ceryle torquata (Liun.). 



Common. Habits almost precisely the same as C. alcyon, but not so 

 noisy, as a rule. 

 One specimen. 

 No. 137. $ ad. March 30. 



43. Ceryle americana cabanisi (Tsclindi). 



Abundant. The collector is sure to meet with them while following 

 along the streams of that region. They are quite fearless and are not 

 at all disturbed by the presence of man, but pursue their fishing after a 

 short but emphatic expostulation at his api)roach. Iris brown.
