articular surface was about 25 mm. ; the shaft at its narrowest probably 

 had a width of not much more than 10 mm. 



The fibula lies on the outer side of the tibia and closely appressed 

 to it, crossing it at a low angle. It was apparently shorter than the 

 tibia and very slender, being widened at its proximal end. 



Part of the pes is preserved, consisting of a small tarsal bone and 

 the most of one digit, probably the second. The mttatarsal is 

 19 mm. long posteriorly and 14 mm. long anteriorly, the distal sur- 

 face being inclined to the axis of the tibial shaft. The whole axis 

 of the digit is inclined to that of the tibia, so that the animal 

 appears to have been digitigrade. The first phalanx is short, its 

 proximal end broader than the anterior end; the second phalanx is 

 18 mm. long. The claw is incomplete, but was long and compara- 

 tively slender.
