234 SUPPLEMENT. 



Incertce Sedis. 

 Genus CROCODILJEMUS, Jourdan (MS. 1 ). 

 Syn. Chcehsaurus, Jourdan 2 . Alligatorium, Jourdan 3 . 



Characterized by the extreme complexity of the dermal skeleton, 

 in which the scutes are pitted, and by the nearly equal size of the 

 teeth. 



Crocodilsemus jourdani, Lydekker (n. sp.). 

 The type species ; typically of small size. 

 Hab. Europe (France). 



The cast of the type specimen (No. 40344) is entered in Part I. 

 p. 98, as Metriorhynchus (?), sp. 



Subfamily Teleosatjrinj (supra, i. p. 102). 



Genus STENEOSAURUS (supra, i. p. 108). 



Steneosaurus brevidens (supra, i. p. 115). 



R. 1477. A number of associated bones ; from the Great Oolite 

 near Northampton. The chief specimens are portions of 

 the skull, the glenoidal portion of the right coracoid, 

 two imperfect cervical and several dorsal vertebrae, the 

 imperfect femora, portions of ribs, and part of a 

 dermal scute. In the skull the greater portion of the 

 cranial and a part of the mandibular rostrum are 

 preserved. In size the cranium agrees with the one 

 figured on p. 186 of Phillips's ' Geology of Oxford.' The 

 two cervical vertebras agree in size with No. 4821 (supra, 

 i. p. 115), and belong to the anterior part of the neck. 

 The anterior cervical has a blunt haemal carina, and 

 closely resembles the one figured by Phillips, op. cit. 

 p. 200, diagram lviii. The dorsals are smaller than No. 

 R. 79 (supra, i. p. 115), which may indicate a distinct 

 and larger species. Purchased, 1889. 



R. 1477 a. An imperfect anterior cervical vertebra agreeing in size 

 with the cervicals of the preceding specimen ; from the 

 Great Oolite near Northampton. The centrum is entire, 

 but the greater portion of the neural spine is wanting. 

 The haemal surface is deeply concave, and excavated above 

 the level of the transverse processes. Purchased, 1889.
