following peculiar features. The manus seems to be of a Rhyn- 

 chocephalian type ; but the pes has only four digits, in which the 

 phalangeals number 2, 3, 4, 4, or the same as in the Crocodilia. 

 The proximal bones of the carpus are also elongated, as in that 

 order ; and the radius and ulna in the pectoral, and the tibia and 

 fibula in the pelvic limb, are respectively in close apposition. The 

 mandibular symphysis is long ; and the dentition is said to resemble 

 that of the Geckonidce among the Lacertilia. The above characters 

 point to a curious blending of Squamatine and Crocodilian features.
