In conclusion, it is evident that the late Professor Marsh * was 

 justified in regai-ding Getiosaurus as one of the most generalised 

 of known Sauropoda, closely related to the American Morosaurid?e. 

 So far as known, in fact, this English Jurassic genus is scarcely 

 distinguishable from the least specialised American genus Haplo- 

 canthosaurus t, which has remarkably similar dorsal and anterior 

 caudal vei-tebr^e, bvit seems to differ in the moi-e coarsely cancellated 

 texture of the bone in its vertebral centra.
