than the lilac-breasted male, but not so dark as dull violet-blue. It 

 is just becoming slightly bluish on the crown, the rest of the pileum 

 is washed with greenish, grayish olive on the occiput. Nevertheless, 

 I think the lilac-breasted male a younger stage than the dull violet- 

 blue male; these parts have somewhat faded in the former. The 

 dull violet-blue-breasted male was taken in May, but it never would 

 have faded to the lilac stage. There is naturally some variation, 

 either individual or age.

Collocalia inopina pellos Thayer and Bangs. Mem. Mus. Comp. Zool., vol. 40, 

 no. 4, p. 158, 1912 (Washan, west Szechwan). 



One female. Noon forests, east of Muli, 11,000 feet, southwest 

 Szechwan, August. 



The above specimen agrees with skins from the type locality of the 

 race. The wing measures 137 mm. 



60. MICROPUS PACIFICUS PACIFICUS (Latham) 



Uirundo pacifica Latham, Index oruithologicus, Suppl., p. 58, 1801 (Australia). 



One unsexed, Petien or Barongomba, one day's trip northeast of 

 Baurong, 11,000-12,000 feet, southwest Szechwan, no date. 



61. mRUNDAPUS NUDIPES (Hodgson) 



Chaetura nudipes Hodgson, Journ. Asiat. Soc. Bengal, vol. 5, p. 779, 1836 

 (Nepal). 



One adult male, Shouchu Valley, 12,000 feet, southwest Szechwan, 

 August. 



This bird is very different in plumage from Hir^ndapus caudacu- 

 tus, and their ranges apparently do not meet at any point. For these 

 reasons it seems they should be treated as separate species. Hh^n- 

 dapus nudipes resembles H. caudacutus in color but is much darker 

 throughout ; the forehead is dark brown, only a little paler than the 

 crown, not white ; and it is larger. The above specimen has a wing 

 208 mm. long.
