The author finds that metamorphosis is due to conditions which enforce fre- 

 quent use of the lungs and that food and temperature have no effect.

A description of skulls, jaws and pectoral girdle of this species. The skull 

 shows interesting features in the great backward development of the squamosal 

 and tabulares into "horns". The nasals are small. The bones in the temporal 

 region are reduced from the primitive Reptilian-Stegocephalian number of three 

 to a Single bone which the author regards as the squamosal. The palate agrees 

 with 4he primitive forms in the arrangement of the pterygoids but differs from 

 them and approaches the later large Stegocephali in having exoccipital instead 

 of basi-occipital condyles. The author discusses the systematic position of this 

 form. Forster Cooper.

 cies), Mesosuchns broicni and Sderomorus taylori. In the discussion of the group 

 of Pseiidositchia the author considers them a primitive group of great importance 

 as containing the ancestors of both the Dinosaurs and Birds as well as of the 

 Pterodactyles, Enparlccria and OrnitJiosuchus having in general structure prac- 

 tically reached the Dinosaur stage. Forster Cooper.
