DEFINITIONS

MALACORHYNCHUS
(Anatidae; Ϯ Pink-eared Duck M. membranaceus) Gr. μαλακος malakos  soft; ῥυγχος rhunkhos  bill; "The geographic distribution, then, of the true Shovellers may be termed universal. But among these broad-billed Ducks of the southern hemisphere, we find a very remarkable modification of form; the breadth of the bill and the length of the laminæ are nearly the same, but the edge of the upper mandible, instead of being smooth, as in the European species, is furnished with a thin membranaceous skin, which considerably projects, and hangs down somewhat like a wattle on each side. For this form, hitherto uncharacterised, I now propose the name of MALACORHYNCHUS, and I shall view it, for reasons hereafter stated, as a sub-genus. The bill of the European Shoveller is flexible; but in this group it is much more so." (Swainson 1831); "Malacorhynchus Swainson, Journ. Roy. Inst. Gr. Brit., 2, pt. 4, 1831, p. 18. Type, by monotypy, Anas membranacea Latham." (Peters 1931, I, 170).
Var. Malacorynchus.
