12 FOSSIL REPTILES OF DORSET. 



in the squareness of the upper temporal fossae) distinguishes it from 

 all the members of the sub-genus Steneosaurus described by EE. 

 Deslongchamps in his Notes Paleontologiques. Mr. Hulke for the 

 above reasons considers it to be a genus linking the Teleosauri and 

 Steneosauri together, with a nearer likeness to the latter, and, after 

 a review of all its features, suggests placing it in the sub-genus 

 Steneosaurus. I provisonally name it Steneosaurus Purbeckensis. 



GENUS TELEOSAUKUS, Geoff. St. Hilaire. 



TELEOSAURUS MEGARHINUS, Hulke. 



Named by Mr. Hulke from a portion of a snout fifteen inches 

 in length, which could not have been less than three feet when 

 whole. It is slender, tapering gradually to the aperture of the 

 nostril, where it has a large and unusual expansion. The slightly 

 curved alveolar borders contain twenty-four sockets besides four in 

 each premaxilla. From the Kimmeridge Clays of Kimmeridge, 

 and presented by me to the British Museum. 



GENUS GONIOPHOLIS, Owen. 



GONIOPHOLIS CRASSIDENS, OiC&n. 



This genus was thus designated by Sir Richard Owen on account 

 of the rectangular shape of its imbricated dermal plates, which 

 have a projection fitting into a corresponding depression on 

 the surface of the opposite angle of the adjoining plate; the crowns 

 of the teeth are thick and longitudinally striated with a prominent 

 ridge on each side. The knowledge of this well armoured 

 Crocodile has been chiefly derived from one obtained in 1837 by 

 R. Trotter, Esq., from the Middle Purbecks of Swanage. Since 

 that date several portions have been procured both at Swanage 

 and in the neighbourhood. L. Dollo in the Bull. Musee 

 D'Histoire Nat. de Belgique, 1884, gives descriptions and figures 

 of Goniopholis from a large series of remains obtained at 

 Bernissart with Iguanodon. The pelvis differs from that of the 

 existing Crocodile, and its biconcave vertebrae make it probable 

 that it was essentially littoral. It deviates from the Teleosaurs and
