8 Watson, Notes on some British Mesozoic Crocodiles. 



1st. The tapering of the snout is even slower than in 

 our specimen. 



2nd. The nasals are shorter. 



3rd. In advance of the orbit the nasals form the 

 widest part of a transverse section of the face. 



On the other hand the palates agree exactly. Des- 

 longschamps specially remarks on the pronounced medial 

 channel of the palate. 



On the whole the English specimen is probably 

 best regarded as representing a well-marked variety of 

 Ji'. Jiastifer. I hesitate in applying a name to this variety 

 on the evidence of the inadequate material before me. 



It deserves to be noticed that Owen's Steneosatirus 

 temporalis figured in the " British Fossil Reptiles," and 

 said to be from the Bath freestones, is really founded on 

 the type specimen of Phillips' " Steneosaurus palpebrosus " 

 from the Kimmeridge clay of Shotover. Comparison of 

 Owen and Phillips' figures will render this certain, Phillips' 

 name has priority. 



The fact that in this instance Owen has made an 

 error in the geological age of a specimen throws doubt on 

 the horizon of " Steneosaurus geoffroyi and laticeps " which 

 are figured in the preceding plate as from the Great 

 Oolite. Koken has already commented on their resem- 

 blance to Macrorhynchus, and they may quite easily be of 

 later date. The present whereabouts of the specimens 

 is unknown. 



Owen's Steneosaurus latifrons, said to be from the 

 Great Oolite of Northamptonshire, is undoubtedly founded 

 on the specimen in the Sharp collection from the Upper 

 Lias. Comparison of Owen's figure with the specimen 

 renders this certain, for some areas which are restored in 

 plaster on the specimen are indicated as being absent
