No. 2. One of these half-bred ducks mated with a grey drake (A. superciliosa), and one duck was reared, which in colour and size was almost identical with A. superciliosa, but had the speculum green, margined with white, and a slight touch of white on some of the secondary feathers of wing. Could fly strongly. No. 3. This duck, when mated with a grey drake (A. superciliosa), produced a brood in type and colour like A. superciliosa, some of which have reverted to a wild state. For several seasons the first brood have been all dark-coloured, and the second brood always includes pure white, or albinos, and white with markings of dark pencillings and rufous; speculum, green; dark-coloured bill and legs; curled tail-feathers wanting. No. 4. A drake, bred inter se, might be described as in foundation colour like A. superciliosa; slightly tinged on head with green; light colour on cheeks, dark mark through eyes; breast, rufous; speculum, green; tail, and tail coverts, inclining to black, edged with brown; two small curled feathers in tail. No. 5. This season, in a brood of six, reared by a hybrid duck, which might be easily mistaken for a coloured call duck, which was mated to A. superciliosa. The ducks were slightly larger than A. superciliosa.; foundation colour and markings similar, having a washed-out look; sides of breast forward of thigh, white grey, same as lower part of breast of A. boschus. Bill, some blackish green; legs the same. Others, bill yellow, chequered with black; legs, yellowish black; speculum, green, outer edge black, margined with white band above and below. The drake was identical in general appearance to Anas boschus: green head, white ring on front of neck, one curled tail-feather only. Colour of speculum, green, margined with white. Can fly, but are thoroughly domestic. As in the mallard, the bright colouring changes with the seasons. The hybrids lay twice in the season, but few young are reared owing to want of convenient water; and numbers are destroyed by dogs, cats, hawks, and rats. The latter are very destructive.

Art. XXIX.—Note on a large Sun-Fish (Orthagoriscus mola, L.), recently captured at Napier, Hawke's Bay. By A. Hamilton, of Petane. [Read before the Hawke's Bay Philosophical Society, 8th June, 1885.] A Fine Sun-Fish (Orthagoriscus mola, L.) was recently thrown on shore, close to the Port of Napier, in a dying condition; I was fortunate enough to see it soon afterwards, and took measurements and sketches of all the important features.
