. A history of British birds, indigenous and migratory: including their organization, habits, and relation; remarks on classification and nomenclature; an account of the principal organs of birds, and observations relative to practical ornithology .. . ate covering the fore-head, toes marginate. 5. Porphyrio hasthe bill short and stout, the ridge form-ing a frontal plate, the nasal grooveobliterated, so that the nostrils, whichare round or elliptical, seem perforatedin the bone, the toes slightly Fulica has the bill similar to that ofPorphyrio, the nasal cavity partiallyobliterated, the nostrils linear, the ridgeexpanded into a large frontal plate, thetoes broadly margined with scollopedmembranes. Porphyrio is more grani-vorous than the rest, Rallus more ver-mivorous, Crex more insectivorous, Gal-linula more omnivorous, and Fulica, gia-nivorous like Porphyrio, is the mostaquatic; while Parra, with its exces-sively elongated toes and claws, is thebest adapted for walking upon theaquatic plants. For this reason, andbecause it is intermediate in structurebetween the rest, I have assumed it as the genus whichought to give its name to this very distinct family, which isin a manner connected by Rallus with the Scolopacinae, by. Fic. 45, 516 PARKING. Crex and Gallinula with the Pcrdicina? and Phasianinje,and by Fuhca with the Colymbina\ In Britain there are no representatives of the generaParra and Porpliyrio, which belong especially to wann andtemperate climates.
