and is transversely divided, but whether by a fracture or a true separa- 

 tion I am not sure. The metacarpals are Hve in number, and are longer 

 than wide and rather stout, but contracted at the middle. The third is 

 opposite the second and third phalangeal carpals. Of the others, each is 

 opposite the corresponding bone of the preceding series. The number 

 of phalanges in each digit is not ascertainable, as the mauus is partially 

 broken off. 



The femur is much like the humerus, bat is not so expanded distally, 

 its width equaling three-fourths the length. The bones of the second 

 segment are short, the tibia (if the limb be in its normal position on the 

 .block) being the wider of the two. It is wider than long, subquadrate, 

 and but little eraargiuate on the fibular side. The fibjJa is longer than 

 wide, and has an oblique suture with the femur. The three proximal 

 tarsals are subround and subequal in size. The bones of the second 

 row are not preserved. The phalanges are rather elongate, but stout 

 and contracted medially; articular surfaces subround. They diminish 

 in size as far as preserved, the pes being broken off at the end of the 

 fifth.
