14 Watson, The larger Coal Measure Amphibia. 



EXPLANATION OF PLATE. 



A. " Loxomma Al/maiii.'' Right posterior angle of a skull. 

 Dorsal surface. 



The Quadratojugal (Qu.J.) and Squamosal (Sq.) are naturally 

 articulated, but have moved forward so as to separate the faces 

 on the Quadrate and Quadratojugal, which are in contact in the 

 undisturbed skull. The Pterygoid (Pt.) and Quadrate (Qu.) 

 are in their correct position. 



The ornament on the Squamosal is omitted and that on the 

 Quadratojugal only partly represented. 



B. The same specimen as A, ventral surface.
