66 Amphibia — Anthracosauridce. 
the orbits are oval, but narrow in front, and are some distance 
in advance of the parietal foramen ( see Fig. 84). 
G api to s aunts and Metoposaurus occur in the Upper Trias of 
Stuttgart ; in the former the orbits are elliptical, and approxi- 
mate to the parietal foramen ; in the latter they are oval, and 
situated in the anterior half of the skull, and widely separated 
from one another. (Figs. 86, 87.)

omitted; from the Carboniferous of Northumberland. About ir, prefrontal.

In the Anthracosaurid^s, represented by Loxomma , 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 mucous canals 
between the orbits and the nares form a lyre-shaped pattern, 
known 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 Reptile from the Coal Measures of Shrop- 
shire, referred to Loxomma 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. 
This family comprises Baphetes , from the Carboniferous of 
Nova Scotia ; Anthracosaurus and Loxomma , from the Lower 
Carboniferous of Burdieliouse, near Edinburgh, and the Coal 
Measures of Lanarkshire and Northumberland; Macromerium ,
