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. {103} ANAS FINSCHI VAN BENEDEN. _Anas finschi_ Van Beneden, Journ. Zool. IV, p. 267 (1875); Ann. de la Soc. Geol. Belg. II, p. 123 (1876). This duck is most peculiar, as it stands intermediate between _Querquedula_ and _Dendrocygna_ in structure, and its nearest known ally seems to be the extinct _A. blanchardi_ of Europe, and of living forms apparently _Clangula clangula_. Skull nearest to that of _Clangula clangula_ but wider, nostrils more elongated, eye-sockets smaller, and the whole skull more regularly rounded off. _Sternum_ differs from that of _C. clangula_ by having the notch lower, more faint behind and shorter in front. Clavicle and coracoid resemble those of _Fuligula marila_. Humerus larger and stronger than in _F. marila_ and _C. clangula_, as are the femur, tibio-tarsus and tarso-metatarsus, which are almost double as long and thick. Judging from the shape of its leg-bones this bird must have been a strong runner, and probably at the same time was a poor flyer. Habitat: Middle Island, New Zealand. ANAS THEODORI NEWT. & GAD. _Anas theodori_ Newton & Gadow, Trans. Zool. Soc. XIII, p. 291, pl. XXXIV, figs 11-17 (1893--Mauritius). Messrs. Newton and Gadow founded this species on a fragment of a sternum, a pair of coracoids, eight humeri, and a pair of tarso-metatarsi. These are referable to a duck of larger size than _Nettion bernieri_, and somewhat intermediate between _N. punctata_ and _Anas melleri_.
