DICYNODONTID^]. 17 muzzle, and the facial portion of the moderately long premaxillae devoid of lateral ridges; supraoecipital with a deep bar above foramen magnum ; inferior aspect of mandibular symphysis rounded. Vertebral centra (when known) with deep terminal cups. Scapula (when known) with the acromial process separated by a notch from the glenoidal portion, and a long emargination on the preaxial border, which is but slightly reflected towards the dorsal aspect (see p. 21).. Dicynodont.—Dorsal aspect of the right side of the pelvic girdle; from the Karoo system of the Cape. ^. il, ilium; is, ischium ; pb, pubis ; of, obturator foramen. In the upper figure the pubis and ischium are repre- sented in their natural position, while in the lower one their whole contour is shown. A diagrammatic restoration of the palatal aspect of the Dicynodont skull is given in fig. 41. It is probable that at least the majority of the species attained very large dimensions. 1 In the restoration given by Seeley in the * Phil. Trans.' for 18S9, p. 246, fig. 3, the median processes of the pterygoids are represented as uniting and extending forwards to join the vomer. PART IV. C.
