 with blackish slate or dull slate-blackish, the bars narrower and 

 more sparse (sometimes nearly obsolete) on abdomen; under mng- 

 coverts and axillars white, the former narrowly and irregularly barred 

 with deep gray, the latter more regularly barred with darker gray; 

 under surface of remiges deep brownish gray (between deep neutral 

 gray and mouse gi'ay), the subbasal portion of inner web of outermost 

 primary and greater part of inner web of other primaries with broad 

 bars or transverse spots of white — the proximal portion of second and 

 third (from outside), however, immaculate deep gray for a consider- 

 able distance; bill horny black, the mandible bluish in middle, yel- 

 lowish basally; rictus, bare orbital space, and iris yellow; inside of 

 mouth orange-yellow; legs and feet deep yellow;'* length (skins),

Adult female. — Similar to the adult male and perhaps not always 

 distinguishable, but usually (?) " with chest (especially lower portion) 

 suffused, more or less, with pale brownish buffy and showing faint 

 bars of darker; length (skins), 299-300 (299.7); wing, 202-205.5

 20.5-22 (21); middle toe, 18.5-19 (18.8).<* 



« According to Stejneger. 



& Eight Bpecimens. 



c In the series examined there are only three specimens determined by their 

 collectors aa females. Two of these are as described above, the third lacking the buffy 

 suffusion but showing faint grayish bars on the lower chest, the plain pale gray of 

 the tliroat being thus much less abruptly contrasted with the barred under parts 

 than in adult males. A single male (probably immature) has even a stronger suffusion 

 of brownish buffy on the lower chest than either of the females mentioned. 



d Three specimens, from Wa Shan (West Szechuan) and Pekin, iJhina. These may 

 not be C c. telephonus. They are evidently the same form of which measurements 

 of the males are given below, which seem too small to represent this identical form 

 of the species.
