SIPTORNIS STEINBACHI Hartert 



Siptornis steinbachi, Hartert, Nov. ZooL, vol. 16, December, 1909, p. 213. 

 (Cachi, Salta, Argentina, altitude 2,500 meters.) 



The skin of a female Siptornis secured March 13, 1921, near the 

 city of Mendoza, is referred to the present species with some reserva- 

 tion. The bird under discussion was taken in the same type of 

 country as that inhabited by the one allotted as S. d. crassirostris 

 and resembles that bird in general appearance, differing in lack of 

 a rufous throat patch, in blackish bill, and deeper rufous on wings, 

 under tail coverts, and flanks. The throat has a faint yellowish 

 tinge in the center, with obscure blackish tips on the feathers. The 

 specimen, apparently adult, is in full molt, and has only three rec- 

 trices, the external ones on the right side. The two outermost are 

 cinnamon, the third is cinnamon save for a blackish stripe, that 

 extends along the middle of the distal half of the outer web and 

 spreads to the shaft at the tip. The skin agrees substantially with 

 the original diagnosis except for the dusky streaks on the lesser 

 wing coverts. The specimen has the following measurements: 

 Wing, 64; tail imperfect; culmen from base, 14.4; tarsus, 22 mm. 

 These correspond closely to the measurements given by Hartert for 

 his type, namely, wing, 66 ; culmen, 14 ; and tarsus, 22 mm. 



The bird does not seem to have been reported before save from 

 the type-locality from which no specimens are available for com- 

 parison. 



SIPTORNIS BAERI Berlepsch 



Siptornis Meri, Berlepsch, Bull. Brit. Orn. Club, vol. 16, May 28, 1906, 

 p. 99. (Cosquin, Cordoba.) 



Five specimens of this species were taken at Victorica, Pampa, 

 on the following dates: December 24, 1920, adult male; December 

 27, immature male ; and December 28, two adult males, one immature 

 female. The species is easily distinguished from S. sordida, which 

 it resembles superficially, by its heavier more robust bill and the 

 darker median rectrices. Skins in juvenal plumage differ from 

 adults in lighter ventral surface, more indistinct throat patch, and 

 fine vermiculations of duslcy on breast. 



The species inhabits the same type of country as that frequented 

 by Synallaxis a. albescens, a species quite similar in general appear- 

 ance. Apparently haeri rears two broods during the season, as 

 adults taken in December were in breeding condition, while a first 

 brood was already on the wing. 



Victorica marks a slight extension in the previously known range.
