Satvin—Diomedea bulleri, 441, 448. 
GopmMan—Diomedea bulleri, liv, 344, pl. 98. 
In the four specimens of T. bulleri under examination, the 
culminicorn is separated basally from the latericorn by a mem- 
brane that is wider than the membrane in some specimens of 
T. cauta. At the frontal feathers, however, the membrane in 
T. bulleri is very narrow, at most being scarcely more than a 
line.
