102 Bangs — Birds from Costa Rica and Chiriqid. 



with his accustomed generosity, told me to keep a series for my 

 own collection and to arrange the duplicates for exchange — 

 probably with the National Museum. 



As was to be expected there proved to be several new forms 

 and several new records for Costa Rica in the Underwood collec- 

 lection, besides which the fine material from the neighboring 

 country gave me an opportunity for comparison of Chiriqui 

 birds — collected by Brown — that I never before had had, result- 

 ing in the discovery among them of one or two new forms. 



The following nates and descriptions are the results of my 

 work on the Underwood collection, which also meant going over 

 again all of Brown's Chiriqui collections. 



Botaurus lentiginosus (Mont.). 



One 9 taken at Reventazon, November 5, 1 899,' appears to be the first 

 Costa Rican record for the species. 



Ereunetes pusillus (Linn.). 



One 9 from vicinity of San Jose, September 15, 1898, adds this species 

 to the Costa Rican ornis. 



Heteropygia bairdi (Cones). 



Baird's sandpiper must also be given a place in the Costa Rican ornis, 

 on the strength of one 9 taken by Underwood at Cerro de la Candelaria, 

 near Escazii in October, 1900. 



Leptotila cassini vinaceiventris (Ridg.). 



In the Underwood collection are two doves, both adult males, labeled 

 Leptotila cassini, one of them so identified by Salvin, one from Volcan Mi- 

 ravalles, September 11, 1895, the other from Juan Vinas, March 20, 1902. 

 The Miravalles specimen is tyi)ical vinaceiventris, exactlj^ matching Hon- 

 duras examples. The Juan Vinas ))ird is not quite typical, api)roaching 

 cassini in its grayer breast and slightly darker and more lustrous upper 

 parts. Compared, however, with a pretty extensive series it seems rather 

 nearer to vinaceiventris than to cassini. 



Qeotrygon costaricensis Lawr. 



In 1902* I recorded Geotrygon costaricensis from the Volcan de Chiriqui, 

 on the strength of four adults taken there by W. W. Brown, Jr. 



I was somewhat surprised a little later to see my record discredited in 

 Biologia Centrali-Americana,t where my Chiriqui specimens are referred to 

 Gr. laivrencei Salvin, and this done without seeing my skins or even writing
