displays affinities both with the Pseudosuchia and the Crocodilia. 



By von Huene the Crocodilia are thought to have been derived 

 directly from the Aetosauria. Such a descent implies, among other 

 things, elongation of the snout, the loss of preorbital vacuity, the 

 loss of the clavicles, and the production of a typically Crocodilian 

 coracoid. These changes are partly brought about and partly fore- 

 shadowed in the Notochampsidae : and although the limbs are not 

 moditied in the Crocodilian manner save in the lengthening of the 

 carpal s, it may be concluded with some degree of truth that the 

 family occupies an intermediate position between the Aetosauria and 

 the Crocodilia, possibly on the direct line of descent. It is unfortunate 

 that nothing is known of the palate in either of the two members 

 of the family.

PEDETICOSAURUS LEVISEURI v. Hoepen.

The type consists "of a nearly complete individual on two slabs 

 of matrix. The fossil is an impression of the right side of the skull 

 and limbs, and besides this, consists of some vertebrae, a few ribs, 

 a great part of the tail and of dermal ossifications". 



The skull is only seen in lateral view. It has a total length of 

 abouth 90 mm. The snout is low and fairly long, the front of the 

 orbit lying a little in advance of the middle of the skull. The orbit 

 is large and rounded, the antorbital vacuity small with a straight 

 lower border. The nostrils are almost terminal. The bar separating 

 the upper and lower temporal vacuities is not clearly displayed. 

 The lower border of the lower opening is formed mainly by a 

 shallow jugal. Posteriorly this meets a bone, which, as preserved, 

 has a free upper anterior end, and occupies the same position as 

 the bone which I have called quadratojugal in Nolochampsa and 

 Sphenosuchus. Behind this is a portion of the quadrate with which 

 the lower jaw still articulates. 



The premaxilla carries three small teeth; the maxilla probably 

 carries 16 or 17 teeth, of which the anterior two or three are large. 

 All are pointed, backwardly curved, aud apparently unserrate. 



The bone which van Hoepen has called a "hyoid" is apparently 

 a double-headed anterior cervical rib.
