The above specimen differs as follows from the male assigned to 

 G. lineatus lineaius: The chest feathers have fine white shaft streaks; 

 the white streaks on the sides of chest are broader and extend down 

 on to the flanks ; above, the fine white Imes appear to be somewhat finer; 

 the unspotted inner web and tip of the middle tail feathers are avel- 

 laneous, not white; the crest is greenish at tip instead of. steely blue. 



Gjddenstolpe ^^ says that authentic specimens have hitherto been 

 collected only in the Meh Taw forest. Gates, in the description of 

 this form, says that while the ranges of this and G. I. lineatus approach 

 each other very closely, sharpei occurs at liigher elevations. Stuart 

 Baker "° gives the range as the South Shan States, East Central 

 Burma, and Siam. 



GENNAEUS LEWISI Delacour and Jabouille 



Gennaeus lewisi Dklacour and Jabouille, Bull. Brit. Orn. Club, vol. 48, p. 125, 

 1928 (Bokor, south Cambodia). — Delacour, Ibis, 1929, p. 202, pi. 5. 



One male, Kao Kuap, Krat, December 25, 1929; one male and one 

 female, Kao Sabap, 3,000 feet, November 13 and 17, 1933. 



Tliis species finds its nearest ally in Gennaeus annamensis Grant, 

 from south Annam, but the pattern of the back is coarser in leunsi, 

 both the black and white concentric marks to the feathers are broader. 

 To accommodate tliis larger pattern the number of white lines on each 

 feather is reduced' in lewisi, and the feathers appear to be larger. 

 Below, in Gennaeus annamensis, the lanceolate feathers on the sides 

 of the neck and chest are either white or white on the inner web, 

 becoming rather broad white shaft streaks on the flanks; this forms a 

 rather broad white line on each side of the black juguhim and chest. 

 In G. lewisi the feathers of the sides of the neck and chest are black 

 with narrow white concentric lines, and the flanks have merely white 

 hair lines along the shafts; in other words, there is no broad white line 

 down the sides to contrast with the black jugulum and chest. 



The female G. lewisi differs widely from the same sex of G. anna- 

 mensis. The back in the latter is a snuff brown; the scapulars have 

 very fine dusky stipphng; the ^\dng coverts are the color of the back; 

 the tail has wavy lines of a lighter color than the basic color and with 

 some dusky markings; below it is a huffy brown with lighter brownish 

 shafts to the feathers. In the female of G. lewi,si the back is chestnut- 

 brown, each feather tipped with light grayish olive and the shaft 

 whitish; wing coverts of the closed wing light grayish oliA^e, with white 

 shafts contrasting with the reddish-brown flight feathers; tail roods 

 brown without markings; lower parts drab with whitish shaft streaks.
