 its proximal fracture, is lj^„ inch wide at the distal end. The 

 distal extremities are rounded from above downward, some-

(fig. 10) is ItV inch wide at the proximal end and H inch at 

 the distal end, 2tt) inches long, and 1 inch thick at its extremi- 

 ties, with all its surfaces slightly concave except the pulh-y- 

 .ihaj)ed distal end, at the sides of which are the usual concave pits. 

 No. /^7S is smaller, being only ly"o inch long, but the reduction 

 in thickness is not in proportion to the less length and breadth. 

 No. 379 is rather more slender and has the sides more con- 

 cave. These phalanges indicate a strong broad foot. The 

 terminal claw-phalanges 382,383,384, 385 present two types; 

 383 (fig. 1 1) and 385 have the posterior articular surface, which

is deeply concave, raised above the ground by a deep inferior 

 callosity, while in the other two there is no callosity. The 

 depth of the posterior end of no. 383 slightly exceeds l^ inch j 

 an oblique ridge descends the articular surface. The claw is 

 compressed from side to side, convex above, concave below, 

 tapering downward in front, but imjjerfectly preserved for a 

 length of 2^ inches ; it may have lost half an inch. A small 

 lateral groove runs along the middle of the side. The thick- 

 ness of the bone posteriorly is only about h inch. No. 382,
