NO. 5 NEW DINOSAUR FROM WYOMING GILMORE 5 



Relationships. — The non-union of .the pubes in front of the sacrum, 

 the slender post-pubic processes extending- parallel to the ischia, and 

 the characteristic bird-like hind feet show Thescelosaurus to be a true 

 member of the suborder Orthopoda or Predentate dinosauria. Pro- 

 visionally this genus is here referred to the family Camptosauridce. 

 From Dryosaurus, Laosaurus, and the English Hypsilophodon it 

 may at once be separated by the greater length of femur as compared 

 with the tibia. From Camptosaurus it is to be distinguished by the 

 rounded rod-like pubis as compared to the flattened blade-like pubis 

 of that genus. Additional characters are to be found in the fore-feet, 

 i. e., an additional phalanx in digit III, and the non-coalescence of the 

 first metacarpal with the carpus.
