SUPPLEMENT. 243 



The vertebrae on which this species (the type of Bothriospondylus) 

 was founded indicate an immature and perhaps foetal Dinosaur, 

 which may be the young of Pelorosaurus Jiumerocristatus or of P. 

 manseli ; or may perhaps be a smaller form allied to Pleuroeoelus. 



Genus HOPLOSAURUS, Gervais \ 

 Syn. Ornitho2isis, Seeley (supra, i. p. 146). 



The ischium is wider in proportion to the pubis than in Peloro- 

 saurus leedsi, a difference which may probably be regarded as 

 indicating the right of the present form to stand as a distinct genus 



Hoplosaurus armatus, Gervais 2 . 



Syn. Ornithopsis hulkei, Seeley (supra, i. p. 146). 



Ornithopsis eucamerotus, Hulke {supra, i. p. 146). 

 Pelorosaurus armatus, Lydekker 3 . 



The type species : founded or. the tooth represented in Pt. I. 

 p. 147, fig. 24. The dimensions of some of the bones are given in 

 the table on p. 240. 



Suborder THEROPODA {supra, i. p. 154). 



Family CCELURID^E {sup ra 3 j " \ 



In the definition of this family it should be stated that the middle 

 and posterior cervical vertebrae may be amphiccelous. 



Genus CALAMOSPONDYLUS, Lydekker 4 . 



Known only by cervical vertebrae, which are relatively shorter 

 than in the type genus, and were probably all opisthoccelous. 



C alamo spondylus foxi, Lydekker 5 . 



The type and only described species. 

 Hab. Europe (England).
