Although the various bones of the skeleton were generally found distributed, a number Were discovered associated with each other, the remains of one individual. These consisted of the hunie- Tus, ulna and radius of the left fore limb, a metatarsal and phalanges of the pes, the zygapophyses of cervical vertebrtc, ribs, fragments of teeth, broken ossilied tendons and impressions of the integument. The species is represented further by disassociated femora, tibize, inetacarpals and phalanges of the manus, rami ofthe lower jaw and maxillte with remarkably well preserved teeth in place, dorsal and caudal vertebrtc, a pubic bone, ischia, ilia, chevron bones and numerous teeth as Well as other remains probably referable te the same species.</paragraph>

<paragraph blockId="46.[228,2024,465,2070]" pageId="46" pageNumber="71">The humerus, ﬁgs. 1 and 2, has a prominent radial crest that extends, from the external tuberosity above to slightly more than half way down the shaft externally and is roughly striated at its lower end ior the attachment of the deltoid muscle. The head is small and is supported below by a strong rounded ridge. The proximal end, seen from above, is roughly triangular in shape, the front face broadly excavated with conspicuously concave surfaces on either side of the head behind that continue forward to meet the inner and outer‘ tuberosities. The condyles are separated by a deep depression behind, that extends up the shaft for a short distance; in front they are not so conspicuously divided.</paragraph>
<paragraph blockId="46.[228,2024,465,2070]" pageId="46" pageNumber="71">
An archaic feature is expressed in the great downward extension and conspicuous singularity of the radial crest. In comparing this humerus with that of Hadrosaurus Foulkii, *

, is interesting in many particulars, notably, its slenderness, the prominence of the head, the backward extension of the condyles and the marked development of the third trochanter. The inner condyle is larger than the outer one,‘ they are both, viewed from the side, broadly rounded posteriorly and pointed in front. From the great trochanter, a prominent ridge extends dowrrward, for some distance on the outer front face of the bone.

, robust, high at the centre, sloping downward toward either end, the dental chamber occupying nearly the whole of its length. Seen from above, the posterior half slopes obliquely forward and outward, while the reverse is the case in front; at the extreme anterior end there is a limited slope inclined obliquely outward. Also, viewed irom above, the posterior half is straight and broader than the front half which narrows to a- rounded, outwardly turned point. Inner surface rather flat. Outer surface with a rounded ridge running horizontally from the posterior end to meet the facet for the articulation of the anterior end of the jugal. On the inner, upper side behind mid-length, a facet, probably for the palatine, is present. Teeth replacing each other from the inner side, apparently not more than two, of a series in v;se in the grinding surface at the same time; the carinated, enamelled faces of the crowns facing outward. A row of foramina, similar to that of the lower jaw, conspicious in the upper part of the inner side. Several large foramina occur in the anterior half of the outer side.
