Cross-section of beak of fowl behind nostril ; o. e., outer ethmoidal fold. is so short that the narial aperture is very wide and the outer ethmoidal fold is exposed to view. The nostril may be said to be wide or " high " (figs. 7, 12). Sometimes the upper margin of the nostril may even be elevated above the level of the culmen of the beak, and in this case a transverse fold crosses the culmen from nostril to nostril. This I call the ctilminal fold. The morphology of the nostril of the Polish fowl seems to be little under- stood. The term "cavernous" is applied to this form by the American.
