Not illustrated. 1909 edition. Excerpt: ... of the ellipse about parallel with the zygomatic bar. In the recess of the angle between this septum and the frontal bone, we find the double groove for the lodgment of the olfactory nerve. the grooves commencing directly in front of the olfactory foramen, running parallel with each other quite up to the opening for their passage through the aliethmoidal plate. The zygomatic or jugal bar is very slender in Circus, and the sutures of its original elements are quite obliterated. Its quadrate end develops at right angles a peglike process, to articulate in a corresponding pitlet in that bone. The maxillary or anterior extremity has already been sufiiciently described. Its relations with the palatines and maxillopalatines are well shown in figures I9 and 21. The superior margin of the orbit is rounded, but as this proceeds backward it soon liecomes sharp. a condition it retains to the very tip of the sphenotic process. At the back of the orbit the wall is broad and gently concave throughout; it being pierced at its lower and inner angle by a circular optic foramen, and the foramina more external to it are quite distinct from each other, which is-by no means the rule gen: erally among birds. The outline of the olfactory foramen leading into the brain case is very irregular, and the wall in its immediate neighborhood is thinned to the extent of perforation in one specimen before me, while in another two minute foramina occur, just large enough, on either side, to admit the passage of the nerves, and the aforesaid perforation is much smaller. Quite an extensive osseous flap is thrown out to shield the opening to the ear behind. This latter aperture is comparatively very large, the opening being fully equal in size to the corresponding one in a...
