the sixth, and longest in the wing. Feathers soft and fluffy. 

 This is an extremely curious mountain-form of the Sylviadce, 

 combining many of the characters of Calliope, lanthia, Larvi- 

 vora, Pratincola, &c., with those of the Blue Flycatchers, Niltava, 

 Hypothymis, &c. It is closely allied to M. leucura, Hodgs. 

 (see Jerdon, op. cit. vol. ii. p. 118), but wants the blue eye-streak, 

 and has a shorter and differently marked white and black tail. 

 Jerdon notes a third species, M. diana, from Pegu. 



The third and fourth novelties were brought down on the 

 15th March ; they belong to the families Muscicapida and Tur- 

 dida respectively.

First quill small ; fourth longest in wing. Tail of twelve 

 graduated feathers, with obtuse mucronate tips ; the outer ones 

 about half an inch shorter than the two central, which are 0*2 

 in. longer than the rest, and are narrower, with the shafts 

 more median, the feathers narrowing and ending in blunt tips. 

 Claws rather curved, and laterally cultrate. Some of the feathers 

 of the abdomen and flanks white, with buff tips, the white not 

 showing unless the feathers are disturbed. 



This species seems to be the Formosan representative of the 

 Himalayan Cyornis rubeculoides, Vigors (Jerdon, Birds of India, 

 vol. i. p. 466), from which it differs in its rather larger size and 

 more vivid colouring, in the intense brightness of its blue rump, 

 and in having the chestnut-buff of the breast diffused over the 

 rest of the lower parts. 



Turdus albiceps, sp. nov. s • Capite toto albo : partibus supe- 

 rioribus cum pectore et axillaribus olivaceo-nigris : partibus 

 inferioribus castaneis, lateraliter olivaceis : crisso albo, nigro 

 castaneoque guttato : rostro pedibusque aurantiacis. Long, 

 tota 8-8 poll. ; alse 49 ; caudse 3-3.
