CffllOMIS MIIVOR, Hartlaub. Sheathbill; Bec-en-fotjrreatj. HISTOEY. The genus Chionis was founded by J. R. Forster in 1788,* upon C. alba, discovered by him in the neighborhood of Cape Horn. In January, 1841, Dr. G. Hartlaub wrote from Bremen to the Eevue Zoologique t that he had discovered a new species of Chionis in the museum at Ley- den. He described it as differing from G. alba by its decided inferi- ority in size, by the blackness of the entire beak, and particularly by m the extraordinary shape of the sheath of the bill. His original descrip- tion and measurements are as follows: "Chionis minoe, JSfob., nivea, rostro nigerrimo,pedibus saturatefmces- centibus, spatio supraoculari subrotundo, nudo, nigra, rostri vagina sub- concava, antrorsum ascendente, apertd {in Ch. alba,plana, incumbente).
