The Pamphlet Collection of Sir Robert Stout: Volume 73

Diomedea bulleri, Rothschild. (Buller's Albatros.)

Diomedea bulleri, Rothschild. (Buller's Albatros.)

The bird which has hitherto been called Diomedea culminata in our New Zealand lists has been pronounced by Mr. Salvin a new species, and is described in the Ibis (vol. v., 1893, p. 572) by Mr. W. Rothschild, who has been good enough to dedicate this new form to myself. The type of the species, besides a very large series of representative specimens, are in the Rothschild Museum at Tring.

The following is the diagnosis: Thalassogeronti culminato quoad colores similis, sed rostro pallidiore, culmine ad basin latiore, ad latera attingente, culmine omnino flavo; alis subtus niveis. He adds, "It differs materially from the true Thalassogeron culminatus (Gould), a species of Ridgway's geuus Thalassogeron, the base of the culminicorm being page 122 separated by an interval of soft skin from the latericorn. In. this respect the present species is somewhat intermediate between Diomedea and Thalassogeron, but the base of the culminicorn, though not so well developed, distinctly spreads and has a well-defined posterior margin."
