In the Anthracosau7-id(B, represented by Loxovima, the skull 

 is vaulted with a broad and somewhat spatulate muzzle ; the 

 length of skull being about 14 inches by 9 inches in breadth. 

 In this family the vertebral column is fully ossified in the 

 adult ; the teeth are deeply infolded ; the mucus-canals 

 between the orbits and the nares form a lyi-e-shaped pattern, 

 knoAvn as the lyra ; and the ventral surface of the body typically 

 has a covering of bony scutes. 



In Wall-case 11 is placed a very beautifully preserved 

 skull of a Labyrinthodont fi-om the Coal Measures of Shrop- 

 shii-e, referred to Loxovima Allmani (Huxley). The specimen is 

 preserved uncrushed and shows the natural contour of the skull 

 and lower jaw, admirably preserved in clay-ironstone. It was 

 presented by George Maw, Esq., F.L.S., F.G.S.
