Hab. South Indian Ocean. Specimen in Nat. Mus. Washington. 



This bird belongs to the same group as the common Procellaria glacialis of 

 the Northern seas and P. Pacifica of the Northwestern coast of America, both 

 of which are included in the restricted group Fulmarus. The tertiary quills 

 in the present species are white, which is a strong character, in addition to 

 which it is larger and much lighter colored than either of the species men- 

 tioned. In the one character of having the tertiaries white, this bird resembles 

 P. antartica, Gray, Voy. Erebus and Terror, Birds, pi. 33, but in no otber. 

 The bill in the present bird is yellow, and precisely of the same form as in P. 

 glacialis. One specimen only is in the collection of the expedition, and is 

 stated to have been obtained in the Indian Ocean.
