Not illustrated. 1876 Excerpt: ...depression for the ear. Posteriorly these borders pass upwards and backwards, forming processes, which approach and often touch the processes of the exoccipitals: thus form. ing a notch or a foramen, which passes from behind into the depression for the ear. Anteriorly these halves are bordered by slight eminences, which pass from the anterior, inferior angle of the depression for the ear to the base of the Rostrum Sphenoides. Directly under the base of the Rostrum Sphenoides, there is a horizontal, triangular depression, which has for its floor a prolongation of the antero-posterior ridge which has already been described as dividing the inferior face into halves. On each side of the base of the Rostrum Sphenoides. there is a horizontal fissure. Near its base, the Rostrum Sphenoides bears, on each side, an articular surface which looks downwards and outwards, and serves for the articulation with the pterygoids. The upper or internal surface of the basisphenoid is irregular. Posteriorly it slants backwards; anteriorly and at the base of the Rostrum Sphenoides, there is a deep circular depression. This, like the other bones of the skull, is so closely united to the adjoining bones in the adult skull, that it can be studied satisfactorily only in the young bird. In the skull of the hawk, the inferior face of the basisphenoid is divided into halves by a median, anteroposterior ridge, as in the chicken; but in the skull of the owl, this surface is divided into halves by a depression, instead of a ridge and the two halves instead of being depressed are elevated. Indeed, in the skulls of some varieties of the domestic fowl, the inferior surface of the basisphenoid is not divided into halves by a median ridge. In the goose, the median ridge is short; but generally v...
