18/8.] MR. A. BOUCARD ON BIRDS FROM COSTA RICA. 6U 



237. Oreopyra calol^ma, Salv. 



Many specimens of both sexes from Naranjo, April ; Navarro and 

 Ranclio redondo, May. I have not the least doubt that the bird 

 described as Anthocephala castaneiventris, Gould, is the female of 

 this species. These birds are only met with in the forest. 



238. Oreopyra hemileuca, Salv. 



Two specimens, from Naranjo, April. It seems to be a very rare 

 species. 



239. Petasophora cyanotis, Bourc. 

 Petasophora cabanisi, Lawr. 



Several specimens from the Volcano of Irazu, April. Rather 

 common at the altitude of 8000 feet, feeding on the flowers of a 

 small shrub. They take possession of a certain space containing 

 several of these shrubs ; and when not feeding on these flowers, 

 they perch on a dry branch near the place, and fight all the other 

 Humming-birds that dare to intrude. 



240. Heliodoxa jacula, Gould. 

 Helindoxa henryi, Lawr. 



Several specimens from Naranjo, April; Volcano of Irazu, May. 

 One male, although it is not in very fine plumage, has a bright front, 

 and the throat exactly like the specimens from Columbia. Rather 

 rare in Costa Rica. 



241. Heliomaster constanti, Delattre. 



Only one young male, from San Jose, January ; killed while he was 

 Bucking the flower of an acacia tree. 



242. Thalurania colombica, Bourc. & Muls., var. venusta, 

 Gould. 



Several specimens from San Carlos, February ; and Naranjo. 

 April. It perches on very high trees in the forests, and is diffi- 

 cult to get at. It is a rare species in Costa Rica. 



I spent many hours before I could get the pair which I have, 

 from San Carlos. I could not recognize the bird, because it was 

 standing and feeding on the flowers of a parasitic plant very high 

 on a large cedar tree. I thought it was a new species of Microchera, 

 so small was its appearance. When I killed the first I was quite 

 disappointed, and was sorry to have lost so much time for it. 



243. Klais guimeti, Bourc. & Muls. 

 Klais merriti, Lawr. 



Only two specimens, from Navarro, May : a very rare species. 



244. Microchera parvirostris, Lawr. 



Only one specimen of a young male, given to me by Mr. Juan 

 Zeledon. Excessively rare. Although I knew the exact locality 

 where found, I could never find one.
