Birds of the Island of Formosa. 617 



"Wlien their course ^Yas downwards they resembled nothing 

 so much as a shower of leaves ])lown from one tree to 

 another. The species mostly congregating together were 

 Yuhina hrunneiceps, Alcippe morrisonia, Ailyithaius concinnus, 

 and Paras insperatus, the first-named being by far the most 

 numerous and the most charming in all its habits. P. ater 

 plilosus was among the least numerous, and occasionally the 

 party included examples of the lovely Fire-crest, Reyulus 

 goodfellowi. I always remarked that the flocks were either 

 led or followed by some larger species, usually Actinodura 

 morrisoniana, but sometimes Malacias auricularis. 



" These Coal-Titmice were nesting early in April, and I saw 

 one close to the summit of the mountain, at an elevation of 

 9000 ft., carrying a grub to a nest in a cypress tree. The 

 crest is at all times conspicuous."

Hureites acanthizoides concolor Ogilvie-Grant, Bull. B. O. C. 

 xxix. p. 107 (1912). 



This small Bush-Warbler differs from H. hrunnescens 

 (Hume) from India in having the breast and belly darker ; 

 while from H. acanthizoides (Verr.) from China it is 

 distinguished by having those parts much less yellow. 

 It has been described as follows : — 



Adult male and female. General colour above (including 

 the wings and tail) bro\Ynish-olive, inclining to rufous 

 on the top of the head, nape and mantle, but especially 

 on the outer webs of the secondary quills ; rump washed 

 with yellowish-olive; a blackish patch in front of the eye, 

 above it a pale yellowish-white streak, commencing on the 

 lores and passing over the eye to the occiput ; chin, throat, 

 and chest white, tinged with buff, shading into dull yel- 

 lowish-buff on the head and rest of the under parts. Iris 

 brown ; bill brown, creamy-yellow at the base ; feet dull 

 yellow. 



Male. Total length about 100 mm. ; wing 51 ; tail 47 ;
