Mr. Brown's additional specimens, which are parts of the 

 same foot, comprise three nearly perfect claw-phalanges and 

 a terminal fragment of a fourth, possibly referable to the 

 specimen at Paris. There is also a doubtful fragment, im- 

 perfect at both ends, which has some appearance of being a

 undeveloped, as in Hortalotarsus. The foot appears to have 

 been short and small, with the claw-phalanges wider from
