fibula is rather more slender than the tibia. The raetatarsals were 

 well developed, and twice as long as the ends are wide. 



Melanerpeton fallax (Fritsch) presents a very distinct form of 

 skull, and I entertain but little doubt that it belongs to a distinct 

 genus, which may be easily separated from Melanerpeton, not onlj^ 

 by the skull-form, but by the skull structure. The outline is 

 remarkably constricted posterior to the parietal foramen, anterior to 

 which the shape is a broad blunt triangle. Between the broad 

 pre-maxillary, oblong jugal and triangular pre-frontal a bone appears 

 on the anterior margin of the orbit, which the author omits to name, 

 but indicates by the letter I, that can only be the lachrymal. Post- 

 frontal, post- orbital, and supra-temporal bones appear from the 

 restoration to be blended together. 



A few remarks follow on the relation of Melanerpeton to ArcJiego- 

 saurus.
