and ulna, but lay with its dorsal side up, the middle of the shaft rest- 

 ing on the proximal end of the ulna with its longer axis at right angles 

 to that of the radius and ulna.^ The proximal end of the radius lay 

 in the radial groove on the anterior surface of the ulna. Lying be- 

 tween and upon the palmar side, near the distal ends of the radius and 

 ulna, was a large flat bone, the scapho-lunar, presenting on one side a 

 gently but regularly convex surface and on the other two flat, subequal 

 surfaces separated by a low ridge. 



Metacarpals I., II., III., IV., and V. were in regular order at the 

 distal extremity of the radius and ulna. The proximal ends of meta- 

 carpals I. and V. were closely applied to the external lateral surfaces 

 of the distal ends of the radius and ulna, indicating that in life they 

 articulated directly with these bones perhaps through the intermedium 

 of heavy cartilaginous pads, while the three median metacarpals were 

 still interlocked at their proximal ends, as shown in plate XX., and a 

 little more removed from the distal ends of the radius and ulna, as 

 though to accommodate the supposed scapho-lunar mentioned above. 



The proximal phalanges of all the digits were present and nearly in 

 their normal position with relation to their respective metacarpals. 

 That of digit I. was in contact with its metacarpal but shifted from its 

 normal position so that its external lateral surface was opposed to the 

 distal end of the metacarpal, with its proximal articular surface turned 

 inward toward the median axis of the foot and the distal outward. 

 The proximal phalanx of digit II. was in position at the extremity of 

 metacarpal II., but very much flexed, so that its longitudinal axis 

 stood almost at right angles to that of metacarpal II. The first 

 phalanx of digit III. was found in its proper position at the extremity 

 of metacarpal III, and there was on the palmar side, interposed be- 

 tween it and that bone, a small rounded sesamoid. The proximal 

 phalanx of the fourth digit was in position articulated with metacarpal 

 IV. That of digit V. lay at the extremity of its metacarpal, but with 

 its external lateral surface opposed to the distal end of the latter. 

 These were the only phalanges founei with this foot except the ungual 

 of the first digit, which lay in its normal position with reference to 

 that of the first phalanx as the position of the latter has been described 

 above, except that it was turned on its side and had been moved 



'In a preliminary note in Science I stated that the humerus was in position at the 

 proximal end of the radius and ulna, having misunderstood Mr. Gihtiore in reference 

 to this particular. See Science, Vol. XIV., No. 365, p. 1015.
