Descrij?tion. — Type, immature male, No. 173416, U.S.N.M.; Sapu- 

 cay, Paraguaj^, July 21, 1900; William T. Foster. Upper parts deep 

 umber brown, rather paler on nape and rump, more rufescent on the 

 latter; crown and forehead dull blue, the forehead lighter and more 

 greeni,sh; wings and tail sepia brown, the wing-coverts and outer mar- 

 gins of the wing-quills like the back, some blue like that of the head 

 showing on the bend of the wing; sides of the head and neck dull 

 deep brown, with some admixture of l)luish, the lores deep Inifl'; entire 

 under surface brown, much paler and more rufescent than that of the 

 upper parts, lightest on the chin and middle of the abdomen. Wing,

 10.5 mm,; tarsus, 18 mm.; middle toe, 14.5 mm. 



A female taken June 23, 1900, is quite similar to the immature male, 

 except for the lack of all bluish trace, and being of a noticeabl}^ more 

 rufous hue throughout. Wing, 71 mm.; tail, 65 mm.; expo.sed cul- 

 men, 12.5 mm.; depth of bill at base, 10 mm.; tarsus, 21 mm.; middle 

 toe, 15 mm. 



The two specimens of this new species have been carefully com- 

 pared with a good series of ( 'yanoconipsa cyanea from various i)arts 

 of its range, and they are certainly distinct. Unfortunateh^ the male 

 is not adult, but enough of blue shows on the head and bend of the 

 wing to indicate a color as well as a size difference from Cyanocompsa 

 eycnwa. Compared with Cyanocom2)>iCt glaucoccerulea it has a very 

 much larger and differently shaped bill, though in other dimensions 

 there seems to be no material difference; what there is of blue color 

 is darker, decidedlj^ less greenish; the female is also much more deeply 

 colored throughout. In fact this new species is in nearly all of its 

 characters to some extent intermediate between Cyanocomjjsa cyanea 

 and Cyanoloxia glaucocmrulea.
