(syn. Diomedea Ϯ Northern Royal Albatross D. sanfordi) Gr. ῥωθων rhōthōn, ῥωθωνος rhōthōnos nostrils; "Furthermore, the formation of the narial tubes and apertures differs sufficiently from that in any known albatross to warrant, in my opinion, the erection of a new subgenus of Diomedea. Rhothonia 2 subgen. nov. Naricorn rotund and bulging, the tubes much more prominent than in subgenus Diomedea; nostrils circular in outline, and directed forwards instead of obliquely upward; culminicorn obtusely pointed posteriorly. Diomedea (Rhothonia) sanfordi 3 sp. nov. ... 2 ῥωθωνος, the nostrils. 3 I take pleasure in naming this handsome bird in honor of Dr. Leonard C. Sanford, whose ornithological enthusiasm has led to the assembly of an unique collection of South American water birds." (Murphy 1917).
