354 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 150 



In laboratory examination of 6 stomachs it was found that ap- 

 proximately 90% of the food was vegetable. In part this was a 

 mass of fiber that was not identified. Mixed with it were seeds of a 

 grass (Panicum) , sedges (including Scleria and Fimbristylis) , spurge, 

 and Solanum. The animal food included spiders, Orthoptera, a va- 

 riety of beetles, flies, and ants. 



The label on a specimen in the British Museum (Natural History) 

 received with the Salvin-Godman collection reads "Veraguas, 1876, 

 Arce" and is so listed (without the date) by Sharpe (Cat. Birds 

 Brit. Mus., vol. 23, 1894, p. 142). Inasmuch as Arce at the date in 

 question had transferred his collecting to Chiriqui, the bird probably 

 came from that Province, where this rail is locally common. There 

 are no records from the Pacific slope of Veraguas, as the bird has 

 not been found between eastern Chiriqui (Las Lajas) and eastern 

 Code (El Valle). It is also unknown at present from the entire 

 Azuero Peninsula. 



Outside of Panama this race is found north on the Pacific slope 

 to the Gulf of Nicoya in southwestern Costa Rica, and to the south 

 from Antioquia, in western Colombia, to western Ecuador. 



In spite of the widespread abundance of this subspecies nothing is 

 recorded of its nesting.

These rails are fairly common near Changuinola and around the 

 western border of Almirante Bay. On the Chiriqui Lagoon they 

 have been recorded on Isla Bastimentos and at Chiriquicito and 

 Cricamola. H. von Wedel secured specimens also at Guabo near 

 Chiriqui Grande. Specimens taken by Benson on the Rio Calovevora
