 * Sarcidiornis mauritianus Newton & Gadow, Trans. Zool. Soc. XIII, p. 290, pl. XXXIV, figs. 9-10.

HE evidence on which this species is founded is a single left metacarpal and an incomplete left half of the pelvis. Its specific character is the very large size as compared to the two existing species.

Habitat: Mauritius.

In an old work entitled "Memorandums concerning India" by J. Marshall (1668) in the article on the Island of Mauritius, there occurs this passage: "They are many Geese; the halfe of their wings towards the end are black and the other halfe white; they are not large, but fat and good. Plenty of Ducks." As there is no mention of the caruncle on the bill here or in other authors alluding to geese in Mauritius, Oustalet doubted that these geese were this Sarcidiornis, but I believe this merely to have been an oversight of Marshall's and that his description goes far to prove the distinctness of Newton and Gadow's species.

The allusion to the small size also points to the geese of Marshall being the Sarcidiornis. L'Abbé Dubois in "Les Voyages du Sieur D.B." records the fact that on Bourbon were some wild geese slightly smaller than the geese of Europe but having the same plumage. Their bill and feet were red. It is also probable that wild geese were found on Rodriguez. There is nothing to show what these Bourbon geese were, and as no osseous remains of such birds have been found as yet it is impossible to do more than mention the fact of such birds having been recorded.
