Obs. Horeites brnnnescens (Hume), from India, has the 

 breast and belly paler, while H. acanthizoides, from China, 

 has these parts much yellower than in H. a. concolor. 



Brachypteryx goodfellowi, sp. n. 



Adult male and female. Very similar to the female of 

 B. cruralis (Blyth), but the forehead, lores, and feathers 

 round the eye are olive-brown like the rest of the crown, 

 instead of rust-red ; the general colour of the upperparts is 

 dark olive-brown and the tail is darker, with hardly a trace 

 of rufous. The concealed white eyebrow-stripe is well- 

 developed, extending from above the lores to the occiput. 

 The underparts are of a rather more olive-brown, and the 

 middle of the breast and belly more distinctly white. Iris 

 brown ; bill black ; feet brown.

Obs. The Chinese species B. carolince, La Touche [c/. 

 Bull. B.O.C. viii. p. ix (1898)], also has the plumage of 

 the sexes similar or very nearly so, but it is a much smaller 

 and more brightly-coloured bird, with the middle of the 

 breast and belly white. 



Parus ater ptilosus, subsp. n. 



Adult male and female. Near P. ater insularis, Hellmayr, 

 but distinguished by having the median black feathers of 

 the occiput considerably lengthened (about 19 mm.), ex- 

 tending conspicuously beyond the other feathers and forming 

 a marked crest. Iris brown ; bill black : feet slate.
