Mr. Palmer adopts the name unalaschkeiisis from Gmelin, 

 Gmelin's name being based on Latham.^ Latham's description 

 is as follows : 



" Length four inches and a half. Bill very short, dusky : the plumage 

 above dull black, without gloss : beneath, and sides of the head, dusky 

 ash-colour, the last darkest: rump dirty white: tail forked: each feather 

 round at the end: legs dusky. 



"Inhabits Aoonulashka." — Latham, General Synopsis of Birds, Vol. 

 II, Pt. ii, 1783, p. 571. Described from a specimen in the Leverian 

 Museum. 



According to Sharpe (Mon. Hirundinidse, Introd., i8g , p. xl) 

 Gmelin's Hiruiido unalaschkcnsis, "has not since been identified," 

 and, it hardly need i^e added, is never likely to be. That it is 

 not a form of Hirimdo erythrogaster is perfectly evident. Hence 

 if the form proves to be recognizable it will have to be rechrist- 

 ened, Gmelin's name being untenable in this connection
