GEEATEE FEIGATE BIED. 
Caribbean Seas, etc,, are in the female, culmen 120 mm., with the wing 
650 mm. 
I name this form 
Eregata minor nicolli, subsp. n. 
From the Seychelles, Aldabra, Gloriosa, etc., the islands comprising the 
Mascarenes, another subspecies can be recognised, the largest measurements 
of a female being culmen 116 mm., and wing 621 mm. These birds vary 
somewhat among themselves, so that it may be two or more subspecies will 
later be recognised from this group. I propose to name this subspecies 
Fregata minor aldabrensis, subsp., 
selecting Aldabra as my type locality. 
From Christmas Island, Indian Ocean, Dr. C. W. Andrews gave me specimens 
of the two species he found breeding there and which had been identified by 
Dr. Sharpe as Fregata aquila and Fregata ariel. The former is a distinct new 
species, hereafter described, while the latter is a form of Fregata mirror. It is 
very small, however, and the female only measures culmen 107 mm., with 
wing 599 mm. 
I name this form 
Fregata minor listeri, subsp. n. 
In the South Mid Pacific probably quite a distinct form exists which will 
bear the name 
Fregata minor palmerstoni Gmelin. 
This cannot be accurately defined as no series are available from the type 
locality of Gmelin’ s Pelecanus 'palmerstoni, but odd specimens from adjacent 
localities do not exactly agree with birds from other places. 
Montrouzier’s T achy petes chamheyroni may be here temporarily associated. 
There is nothing in the description that would make me place Fregata 
aquikv^ with Fregata ariel, as is done in the Catalogue of the Birds in the 
British Museum. , ^ 
Schauinsland collected a fine series of birds at Laysan for the Horn W. 
Eothschild, and these are easily distinguished by many points and will bear 
the name 
Fregata minor strumosa (Hartert). 
Eothschild’s beautiful series from the Galapagos Archipelago prove 
that two very distinct forms live there, as pointed out by Eidgway but 
disputed by Eothschild and Hartert. 
Eidgway’ s Fregata aquila is the bird breeding on the Southern Islands, 
while his Fregata aquila minor is the bird breeding on Culpepper and 
* Lapsus calami for Tachypetes chamheyroni.
