536 NOTES ON COSTA RICAN BIRDS CHERRIE. 



The parrot-oieeu ('ol«>r of the back readily distiugnishes the females 

 of this species from all others of the genus except cyaneocajnJla and 

 suavissinia. The latter is distinguished by the lemon-yellowish belly. 



Pipra leiicorrhoa. 



Females are bright olive or greenish above; below duller, grayish, 

 or with a grayish shading on the throat, and yellowish on the belly. 

 The axillaries are white or pale yellowish. Young males resemble 

 females but have the throat white. 



Pipra leiicocilla, 



Females are bright olive-green above; entire head and nape slate- 

 gray, with j)erhaps an oliv^e shading; below duller, throat with grayish, 

 crissum and belly with whitish or pale yellowish. Bill much larger 

 than in leucorrhoa. 



Pipra mentalis. 



Females are dull olive-green above (almost the color so named in 

 Ridgway's Komenclature) ; below, more yellowish-olive on throat and 

 breast; abdomen and crissum yellowish ; axillaries pale yellowish, inner 

 edges of quills edged with whitish. 



Trogon elegans, Gould. 



Four specimens were forwarded from Costa Rica for identification. 

 Mr. Ridgway has classified the birds as T. elef/ans, Gould, thus making 

 the tenth representative of the Trogouida? found in Costa Rica. The 

 first of these specimens was secured by Alfaroand Cherrie on the small 

 island of San Lucas, in the mouth of the Gulf of Nicoya, in March, 1889. 

 Mr. Alfaro has since secured a fair series of specimens from the same 

 locality. This I believe extends the southern range of the species. 



Antrostomus vociferus (Wils. ). 



A single specimen taken at San Jose (No. 2823, 9 , Museo Nacional 

 de Costa Rica, San Jose, Feb. 24, 1889, Geo, K. Cherrie), and identi- 

 fied by Mr. Ridgway, proved to be this species, thus extending its 

 southern range and adding another species to the list of Costa Rican 



birds. 



Coccygus minor (Gni.). 



This bird is found on both coasts of Costa Rica, and in the interior 

 to an altitude of about 6,000 feet. 



Chloronerpes simplez. 



A single male from the Pacific side of Costa Rica (Pozo Azul), com- 

 pared with an example from the Atlantic side, is decidedly smaller, and 

 there are some color differences ; however, with only the two exami)les 

 before me I am not sure but that the variation is entirely individual.
