Perhaps the most interesting point in connection with the 

 phalanges is the fact that the claw of the 2nd digit has got a sharp 

 outer side and a rounded inner side. This same condition is found 

 in Massospondylus harriesi and JEtonijx ^wZ-tt.sim. There seems to 

 be little doubt that the digit had a claw with a combing or scraping 

 edge such as is seen in many birds, and the question arises, What 

 had the Dinosaur to comb ? We seem justified in concluding that 

 the dermal covering was probably of a different nature from the 

 scales seen in lizards and crocodiles. As the combing claw is only 

 on the 2nd digit it had clearly nothing to do with scraping the ground 

 or digging, and from analogy with the bird and marsupials almost 

 certainly was used for cleaning the skin and scales. Probably the 

 skin had elongated scales with soft skin between. This would admit 

 of greater freedom of movement and, like the feathers of birds, would 

 require to be cleaned after the animals had been hunting their prey 

 on the muddy banks of the lakes. 



MASSOSPONDYLUS HAKRIESI, sp. nov. 



This Dinosaur, which was also discovered on the farm of Mr. 

 Harries, resembles Massospondylus carinatus sufficiently closely to 

 suggest the advisability of placing it at least provisionally in the 

 same genus. The remains consist of an imperfect humerus, a nearly 

 perfect radius and ulna, and a perfect manus, as well as portions of 

 the femur and tibia, and a number of toe bones all of one individual, 

 and the perfect pes of another individual.
