REVIEW OF AMERICAN BIRDS.

So far as I can ascertain, this species has never received a dis- 

 tinctive 1 npellation. Specimens from ranuma, aj)parontly identical, 

 liave been labelled P. chalybea, by Mr. Cassin and Mr. Lawrence; 

 but as explained below,* 1 cannot agree with their conclusions, or 

 those of Cabanis. 



There are in the collection specimens of a closely allied, though 

 larger species, from Bolivia, which I have referred to the F, do- 

 viestica, named from Azara.'

 Hab. Cayenne. 



Of this species I have never seen a speolmen, or one agreeing nnmistakably 

 with the minute accouut of the above mentioned authors. 



As described by Brisson (L'Hirondelle de Cayenne), it is steel black above, 



with the entire under parts grayiih-browu. Tlie lateral tail featlier exceeds 



the middle by six lines. Length, 6 inches; bill, 9.J lines; tarsus, 5 lines; 



middle toe and claw, 7 lines. Buffon speaks c/ it as lustrous violet black above, 



beneath reddish-gray, veined with brown ; lighter on the lower parts of bell/ 



and crissura. Length, 6 inches ; bill, 9J lines ; tarsus, 5 or lines, etc. The 



size is tbus much as in Brisson's bird ; the lower parts reddish-gray, varied 



with I ^wn, paler behind, instead of grayish-brown. Neither author refers 



to any white whatever on under parts. In size the species agrees better with 



leucogaster than any other true Progne, and it is barely possil)le the two 



may be the same, but I cannot reconcile the apparent differences. It would, 



at any rate, be strictly in accordance with tlie usual law of distribution of 



South American birds to dud the Cayenne species specifically diiTerent from 



the Central American.

(No. 16,834, young male, Bolivia.) Above steel blue, much as in P. stihls. 

 Beneath, from chin to breast, and on sides, smoky brown. Rest of under 

 parts white, the shafts mostly dusky. Feathers tipped with steel blue, form- 

 ing as a kind t>f collar across the jugnium and along the sides of body; no 

 trace of them ou the chin, throat, and abdominal region, not even in the pin 

 feathers. 



A second specimen, also probably young male, is still lighter on the throat 

 and breast, almost white ou the latter, although clouded with brown, aud witk
