4. PRINIA POLYCHROA CATHARIA Reichenow 



Priiiia catliaria Reichenow, Ornith. Monatsber., vol. 16, p. 13, 1908 ("Ta-tsieng- 

 lu-ting in Setschuan"). 



Range. — Szechuan and NW. Yunnan. 



Feathers of front, crown, nape, and mantle blackish brown, suf- 

 fused with chestnut and margined brownish ashy to give a boldly 

 streaked appearance (summer) ; equally boldly streaked, but the 

 feathers overlaid with a rich dark rufous wash which masks the light 

 margins and gives the bird a generally darker appearance (winter). 



Two examples from Kiangyin, Kiangsu Province, agree perfectly 

 with a series of catharia and not at all with a series of panuiistriata. 

 If these birds are not abnormal, it would seem that catharia follows 

 the Yangtze from Szechuan to its mouth. 



5. PRINIA POLYCHROA PARUMSTRIATA (David and Oustalet) 



Suya parumstriata David and Oustalet, Oiseaux de la Chine, p. 259, 1877 

 (Fukhien). 



Range. — East Yunnan, Kwangsi, Kwangtung, and Fukhien. 



Olivaceous brown above, lightly washed with rufescent or ochra- 

 ceous, the feathers of front, crown, nape, and mantle with faintly 

 darker centers which scarcely appear as broad streaks (summer) ; 

 much like catharia in winter but without the strong dark rufous wash 

 and with the dark centers of the feathers much less clearly defined, 

 especially on nape and mantle (winter). 



Two specimens from Hunan Province are intermediate between 

 catharia and parumstriata, having the obsolescent streaking of the 

 latter race combined with the rufous suffusion of the former. 



Parumstriata possesses considerable interest in that the summer 

 dress shows its close relationship to the following more southern races, 

 while the winter dress shows its equally close affinity with the pre- 

 ceding forms. 



6. PRINIA POLYCHROA STRIATA Swinhoe 



Prinia striata Swiniioe, Journ. North-China Branch Roy. .\siat. Soc, vol. i, 

 p. 227, 1859 (Hongsan, NW. Formosa).
