For an additional example of that division of the Ortygidcc to 

 which the subgeneric term of Odontophorus has been given, Mr. 

 Gould proposed, from the marbled appearance of its markings, the 

 specific term of marmoratus , with the following characters : — 



Ortyx (OdontophorusJ marmoratus. Ort. spatio circumoculari 

 niido, coccineo ; j)lu7nis auricular Ibus rufo-castaneis ; crista elon- 

 gatd, laxd, fused, plumis singulis flavescenti-fiisco per medium 

 irroratis; nucha nigrescenti-fuscd, lineis irroratis cinereis angustis, 

 transversim fasciatd ; pritnorum pogoniis externis arenaceo-fulvo 

 guttatis ; corpore inferiore fusco, lineis irregularibus et crebris 

 nigrescentibus cinereis, et arenaceo-fulvis transversim fasciato.

And for an Albatros nearly allied to, but larger than, Diomedea 

 chlororhyncha, and which also differs from that species in the colour- 

 ing of the culmen, he proposed to designate 



Diomedea culminata. Diom. spatio circumoculari nigrescenti- 



cinereo, gradatim pallescente ; facie albd ; vertice corpore subtus et 



uropygio albis ; dorso, alis et caudd cinerescenti-fuscis ; cuhnine
