end is '20 mm. broad and 24 mm. thick. On the radial side it has 

 dorsal and palmar knobs with a hollow between, and on the ulnar 

 side there is also a groove for muscle insertion. The dorsal side is 

 slightly hollowed, but the palmar side is flat. The shaft of the bone 

 is slender and circular. 



The 3rd metacarpal is 53 ram. long, 29 mm. broad proximally, 

 and 21 mm. broad distally, and the thinnest part of the shaft has 

 a breadth of 13 mm. For the 4th and 5th metacarpals the corres- 

 ponding measurements are 42 mm., 20 mm., 16 mm. and 9 mm., 

 and 28, 18, 13, and 11 mm. respectively. 



In the 1st digit the 1st phalanx is 37 mm. long. Its proximal 

 width is 31 mm., its distal width 23 mm. It is so twisted that the 

 claw curves strongly inwards and but slightly downwards. The claw 

 has a length as preserved of 65 mm., and when complete was 

 probably 75 mm. long. It is strongly curved and compressed dorso- 

 ventrally. The greatest breadth at the proximal end is 36 mm. and 

 the thickness, which is greatest on the radial concave side of the 

 claw, 24 mm. There is a large bony process on the radial side 

 at the proximal end for the insertion of the flexor tendon. 



Pubis. Both pubes are preserved, entire save for the ischial 

 articular surfaces. The head of the right pubis is somewhat distorted 

 and the bone has a maximum length of 270 mm. The maximum 

 length of the other bone is 285 mm. The breadth at the distal end 

 is about 50 mm. and the thickness 23 mm. ; but the breadth decreases 

 to 43 mm. and the thickness to 12 mm. in the middle of the bone. 

 The medial portion is very thin; the lateral border fairly sharply 

 rounded. At a distance of 210 mm. from the distal end the public 

 plate is turned abruptly downwards at right angles in its medial 

 portion while the lateral part, now forming the pubic neck, is curved 

 more gently upwards and outwards. The subacetabular process is 

 50 mm. long and 30 mm. broad. The pubic foramen is large. 



The pubis is seen to be longer than was supposed by von Huene 

 for Massospondi/lus carinatus. The distal end is somewhat thicker 

 than in the Plateosauridae. 



Femur. The femur fairly slender and slightly bent backwards at 

 its distal end. The proximal end is bent strongly inwards, more so 

 than in M. carinatus. The trochanter minor is not defined, but the 

 trochanter major stands out as strong, somewhat curved, crest on 

 the anterior face of the bone. The chief measurements are: 



Greatest length ..... 355 mm. 

 Width at head . 75
