PH#OPROGNE, Baird. 
Similar to Progne; the bill and legs weaker. Tail slightly forked, the 
lateral feathers not attenuated, and the wing not reaching beyond its tip. 
Plumage without the metallic lustre of true Proyne. A narrow line of feathers 
attached along basal half or two-thirds of the inner side of tarsus. 
The species of this group have been assigned by authors both to 
Progne and Cotyle, but differ in some respects from both. To 
scattered blue-tipped feathers. A third, perhaps female, has no blue feathers 
beneath. 
It is difficult to say what may be the color of the under parts in the adult male 
bird. It seems as if a jugular or pectoral collar and the sides of body might 
be steel blue, the: chin and throat smoky brown, and the belly and crissum 
white, with more or less concealed dusky shafts to the feathers. Nothing like 
this, in adult plumage, however, is described or known. 
Closely allied to the P. leucogaster, this species differs in considerably larger 
size; paler, almost whitish chin and throat, tendency to steel blue on the 
sides of breast and sides of body, etc. 
(No. 16,834.) Total length, 7.706: wing, 5.40; tail, 3.20; depth of fork, .70; 
difference between Ist and 9th primary, 2.50; length of bill from forehead, 
-49, from nostril, .34; along gape, .90; width, .60; tarsus, .58; middle toe 
and claw, .84; claw alone, .26; hind toe and claw, .50; claw alone, .25. 
This is probably the same species as that referred to by Gray as P. domestica; 
but without specimens from Paraguay, for comparison, I am unable to say 
whether it is the true “domestica,” as based upon a description by Azara. 
Burmeister (Reise La Plata, II, 477), in saying that the adult of domestica, 
from Paraguay, is entirely steel blue, has possibly confounded with it the P. 
elegans, described on a previous page. I see no reason to believe that the 
white belly and crissum are ever wanting.
