Adult. Similar to C fucipliaga, but much darker underneath, 

 the chin and throat especially are dark smoky brown ; feathers in 

 front of the eye very dark brown, the bases being light brown instead 

 of pure white ; upper surface very dark smoky brown, only the wings 

 and tail with slight metallic gloss. Wing 5 inches, tarsus 0*4 . 



Hah. Tahiti and Marquesas. 



Easily distinguished from the true C, fuciphaga by its long wing, 

 which is as long as in the subspecies C brevirostris from the Eastern 

 Himalayas, but the latter has the face and sides of neck and the 

 whole under surface much lighter.

* Though the name leuco2)hcea of Peale is most ill chosen, it cannot be denied 

 that he referred to the present species. 



t The name " CoUocalia ci7ierea " cannot be accepted, because it is the 

 Hirundo cinerca, Gm. S. N. ii. p. 1026 (1788), which is, acoordiiig to Sharpe (Cat, 

 B. X.), a Swallow, a conclusion which is perfectly correct. Keilher the Hirundo 

 IK'Tuviana of Brissou (Orn. ii. p. 498, 1760) nor the "Petite hirondelle noire a 

 ventre ccndre" (Buiil Hist. Ois. yi. p. 673) can with any certainty be referred 

 to the CoUocalia from Tahiti. Hartlaub'.s Heme forsteri (J. /. O. 1854, p. 169, 

 without description) is referred by this author himself as a synonym to Coll. 

 spodiopygia. Gray (Ann. & Mag." Nat. Hist. 1866, xvii. p. 123) quoted it as 

 " ? CoUocalia forsieri."
