URONAUTES Cope .

Genus novum Sauropterygiarum . Cervical vertebrae, like the dorsals and caudals, short and transverse. and distinct from each other. Neural arches and transverse processes coössified at maturity. Transverse processes of the cervicals simple and depressed. Extremities plesiosauroid.

This genus might be referred to Polycotylus, Cope , were it not for the distinctness and greater abbreviation of the cervical vertebrae. From Cimoliasaurus, Leidy , it differs in the eoössificntion of the caudal diapophyses and the much greater abbreviation of the cervical vertebrae. The centra are amphiplatyan in Cimoliasaurus , biconcave in Uronautes . From Pliosaurus , Owen, which resembles the present form in the shortness of the cervical vertebrae, the coössified transverse processes of the cervicals separate it. The present is pre-eminently a short-necked genus of the order.

The remains on which it reposes are the cervical, dorsal, and caudal vertebrae, with portions of limb and rib bones.
