The median part between the two limbs of this bone measures T\ inch transversely and the transverse measurement between its extremities is lT3,y Fig. 9- inch. This therefore gives the approximate width be- tween the points of the pubis with which this bone articu- lated. The ischium and pubis are rather thick bones, show no trace of a dividing suture, are directed somewhat back- ward, and, as usual, are imper- forate. There seems to be a small foramen in the position of the obturator foramen of Cretaceous genera, and in those genera the foramen lies in the ischio-pubic ; In another specimen, marked 11 Bh. Munsteri (GoW.), = Bh. Gemmingi (v. Meyer)," the sacrum appears to include three or four vertebrae. The ilium, which is blended with the sacral ribs, is ly^- inch long, and is prolonged for about the same distance on each side of the acetabulum. The anterior process deepens as it extends forward, and it is about -,% inch longer than the slender posterior process. A minute obturator foramen marks the union of the ischium and pubis, which are directed somewhat backward and blended into a compact os innominatum. The pubis is thick and strong. The pre- pubic bones appear blended into a bow-shaped bar. It consists of a middle straight portion and right and left parts which are inclined to it, though not quite symmetrical as preserved. Each of these three parts would measure about J| inch in length. The transverse measurement over the Rhamphorhynchus longimanus. (Wagn. AM. Miinch. viii. T. xvi.) Fin.
