13. Claravis pretiosa (Ferrari-Perez). Blue Ground Dove. 



A pair, Gatun, April 20, 1911. Iris light pinkish-yellow, bill green- 

 ish with a dark line on the culmen and gonys, feet pink. 

 Female was about to oviposit. 



14. Leptotila verreauxi verreauxi (Bonaparte). Verreaux's Dove. 



Two males, Gatun, May 28, and Minti, October 7, 1911. Iris light 

 yellowish-orange, bill black, feet coral red, circumorbital area deep 

 blue. 



The latter specimen is largely in the Juvenal plumage. 



The call of this bird was a single ''coo," very deceptive as to dis- 

 tance, and in quality resembling two notes of a chord. 



15. Lsptotila cassini cassini (Lawrence). Cassin's Dove. 



A male from Gatun, August 6, 1911; female, Trinidad River, March 

 12, 1911. Iris light yellow, bill black, circumorbital space coral-red, 

 feet red. 



Found in the forest along the trails. This bird has a peculiar habit 

 of bobbing the head and tail, but the movement is not a movement of 

 the entire body as in the sandpipers. 



Nest a frail platform of sticks in a large bush, overhanging the trail 

 through a heavily overgrown pasture, at Gatun. Egg, 1.15 x .83 ins. 



[16.] Oreopeleia montana (Linnaeus). Ruddy Quail Dove. 



RALLID^. 

 17. Aramides cajanea (P. L. S. Muller). Cayenne Wood Rail. 



A male from the Chagres River, below Gatun, June 21, 1911, and a 

 female from Gatun, April 28, 1912, are lighter colored than specimens 

 from the Orinoco delta, especially as regards the gray of the throat and 

 fore breast. Iris red, bill greenish at the tip passing into yellow 

 basally, feet deep reddish-pink. 



A nest found April 27, 1913, at Toro Point, on the edge of woods 

 at the head of a small stream, was made from a bunch of leaves and 

 trash lodged on top of the bushes, eight feet up. A few strips of dead 

 banana leaves, some twigs and a few green leaves had apparently 

 been added to the mass already there. There was one egg, 2.06 x 1.34 

 ins. The bird sat very close and would not leave until the bush was 

 shaken. 



*18. Porzana Carolina (Linnaeus). Sora. 



A female from Toro Point, October 1, 1911. Iris reddish-brown, 

 bill yellowish-green, tarsi greenish-olive. 

 Shot on the bare beach at the foot of a cliff.
