PALÉOZOOLOGIE ET PALÉOPHYTOLOGIF, 209 



A detailed account of the osteological structure of Thescelosaurus negleclus, 

 followed by a discussion of the classification and relationships of the genus. 

 It is shown that Thescelosaurus has its closest afïïnities with Hypsilopholodon 

 of the English Wealden. A hfe restoration, modeled by the author from 

 the type spécimen, is presented for the first time,

 mation OF New Mexico. Smiths. MiscelL Coll., vol. LXXII. No. 14 — 

 1922 — Op. 1-9, pi. 1 and 2. 



The new genus and species Alamosaurus sanjuanensis is established, the 

 type spécimen being fully described and its geological occurrence discussed. 

 This spécimen marks the first occurrence of Sauropodous dinosaurs in 

 undoubted Upper Cretaceous deposits in North America. The article closes 

 with a brief review of other reported occurrences of Upper Cretaceous Sau- 

 ropods.

A critical review of the vertebrate fauna of the Arundel formation in
