from Tahiti. Simultaneously Sharpe {Hist. Coll. Nat. Hist. Brit. Mus., Vol. II., 
1906, p. 199) from an examination of Forster’s drawings in the British Museum 
wrote : “ PI. 68. — Hirundo peruviana {Forst. Descr. Anim., p. 240, 1844 : 
Otaheitee). 
This figure is intended to represent Collocalia francica (Gm.).” 
Hartlaub provided Herse forsteri {Journ. fur Ornith.y 1864, p. 169) for 
Forster’s species, so there is a name available should it be yet recovered. 
Further, geographically it is impossible for a subspecies to occur on Samoa 
and Fiji with a different subspecies inhabiting the Tonga group. 
The subspecies admitted would then read : 
Zoonava francica francica (Gmelin). 
Mauritius and Bourbon. 
Zoonava francica inexpectata (Hume). 
Andamans and Malay Peninsula. 
Zoonava francica germaini (Oustalet). 
Mergui Aj-chipelago northwards to Philippines. 
Zoonava francica infuscata (Salvadori). 
Temate and other Moluccan Islands. 
Zoonava francica subsp. 
New Guinea. 
Zoonava francica terrceregince (Ramsay). 
North Queensland. 
Zoonava francica oherholseri subsp. n. 
Fiji Islands and Solomon Islands. 
Zoonava francica townsendi (Oberholser). 
Tonga group. 
Zoonava francica spodiopygia (Pease). 
Samoan Islands. 
Zoonava francica forsteri (Hartlaub). 
Tahiti. ? Extinct. 
This tentative classification shows improvement on the preceding, but 
will still further be emended when more birds are procured. 
The Fijian birds are noticeably smaller and paler both above and below 
than the Samoan birds, while apparently darker than the Tonga form. There 
is a fine series (over twenty) in the British Museum from Fiji, collected by 
Layard and others, while there are specimens enough to show the variation 
from the other places. There is only one immature skin from the Solomons, 
so that the status of the form living there cannot be proven, but it is probably 
a distinct subspecies.
