This bird agrees well with the plate cited above, upon which the 

 species was based. The description is taken from an adult female col- 

 lected by Lieut. Wirt Robinson at San Julian, Venezuela, August 8, 

 1900 (Coll. of E. A. & O. Bangs). 



Crypturus soui mustelinus Bangs. 



Crypturus soui mustelinus Bangs, Proc. Biol. Soc. Wash., Vol. XVIII (June, 

 1905), p. 151. 



Lower parts richer and darker than in C. s. soui, being rich cinna- 

 mon-rufous throughout, almost chestnut on lower throat and chest ; 

 throat cinnamon-ochraceous, chin white, feathers tipped with ochra- 

 ceous ; upper parts decidedly chestnut-brown throughout, interscapular 

 region and rump finely vermiculated with dusky ; edgings of wing 

 and upper tail-coverts bright chestnut like the sides of the chest, and

 webs. Wing about 127 mm. 



Crypturus soui panamensis n. subsp. 



Type, adult 9, Loma del Leon, Panama, Mar. 25, 1900, W. W. 

 Brown, Collector. Collection of E. A. & O. Bangs, No. 7055. 



General coloration similar to C s . soui, differing as follows: Chin 

 and upper throat white, feathers slightly tipped with buff on lower por- 

 tion ; lower throat and upper chest dusky grayish-brown, extending 

 around on sides of chest and neck where it becomes darker, blending 

 with color of the back ; rest of lower parts more like C. s. mustelinus in 

 the intensity of the coloring, but there is always a slight grayish-brown 

 cast. Upper parts very similar to C. s. soui, except that the pileum 

 is much darker, being deep sooty, without grayish tinge. Wing aver- 

 ages 130 mm. in $, c? averages smaller. 



Young birds resemble somewhat the adults of C. s. modest us, but 

 may be distinguished by the white throat and paler upper parts. 

 Eight specimens.
