PELECANOIDES URINATRIX.

ou finding that these specimens, which from the locality uudonbtedly represent the 

 original F. itritiatrix, are fully up to the dimensions of the suiiposed larger (/arnt><j, from 

 the west coast of South America. Observed variation in the color of the feet, which 

 is one point that has been relied upon, lessens the probability of distinctness, especially 

 as the ascribed coloration does not coincide in every case with the dimensions. The size 

 and proportions of the examples examined, as carefully measured in the iiesh by Dr. 

 Kidder, warrant me in adducing the garnofi of Lesson as a synonym of urinairix ; to 

 which I still refrain, however, from adding the herardi of Quoy and Gaimard. — C. 



List of specimens, with measurements. 



BiXl generally black ; laveuder-blue at quadrate basal portion of lower 

 mandible. Ui^per mandible hooked 5 both much compressed and flat- 

 tened ; square at base. ^N^ostrils placed far back, opening upward by a 

 heart-shaped aperture, divided by a longitudinal partition, as if the 

 upper half qf a tubular inclosure had been cut off, parallel to its long 

 axis. 



Iris ash-colored ; not visible during life, when only the black pupil 

 appears. 



Kead blue-black above ; throat white. 



Body^ upper parts blue-black 5 throat, breast, belly, and under part of 

 tail white. Under down yarn-blue. Skiu of belly naked. Plumage 

 very fine and close. The body is remarkably large and heavy in pro- 

 portion to the length of the wing ; the latter being concave, similar to 

 that of the quail. First and second primaries equal in length. 



Tarsus and foot are placed very far back, nearly in the axis of the 

 body; lavender-blue; not scutellated ; no rudiment of hind toe. 



Claics black ; middle claw turned outward. 



Tail very short, black above, white below.
