[Eeceived July 2, 1877.] 



Procellaria albigularis, sp. nov. 



Head, quills, and tail sooty black ; back, shoulders, and wing- 

 coverts lighter, more of a sooty brown ; the largest row of the upper 

 wing-coverts at the tips washed with light brown, forming an ill- 

 defined narrow cross band ; the black of the head covers the sides and 

 the chin-margin ; below the latter is a semilunar white space, ex- 

 tending laterally to below the ear-region and bounded below by a 

 very broad sooty black cross band, which commences at the junction 

 of the wing ; below this the remaining undersurface is white, as is 

 the hind portion of the rump and upper tail-coverts ; the longest 

 under tail-coverts are sooty black, as are the under wing-coverts 

 along the carpal and hind margins ; the middle row of under wing- 

 coverts white, as the axillaries ; the greater under wing-coverts ashy, 

 with white tips ; the feathers of the sides of the vent and flanks 

 with black shafts, forming very narrow dark striae ; tail-feathers on 

 base of inner web white, passing into brown. Bill and feet black. 

 Tail forked, its feathers very broad and truncated at the apex ; the 

 wings reach a little beyond the tail. 



Hab. Feejee Islands, South Pacific. 



The above description is taken from a female specimen from Kan- 

 davu, Feejee Islands, taken on the nest on the 10th of September, 

 1876, and sent over by Mr. Theodor Kleinschmidt to the Museum 

 GodeflProy. 



The large size, the deeply forked tail, and the singular coloration 

 distinguish this species at once from any other member of this 

 group.
