446 Dawson—New Carboniferous Batrachians of Nova Scotia. 
lizard-like in form, with a somewhat flat and broad head and 
strong teeth with folded dentine. Its back was covered with a 
shining skin filled with microscopic horny scales. Its sides were 
marked by vertical bands separated by delicate indented lines. 
Anteriorly it was ornamented with numerous cutaneous lappets 
or pendants. The sides were bordered wi 
above mentioned, found in 1859. Hylonomus Lyelli had a far 
more ornate set of cutaneous appendages, as evidenced by re

The bones of this genus are all, I think, referable to H. Lyelh, 
and to specimens about the size of those previously found. 
They throw little additional light on its character, except to 
indicate that it was probably very abundant, and to render it 
probatle that the specimens formerly described were adult. 
Pwo of the skulls in the tree of 1876 are better preserved than 
those previously known, and confirm the statement already 
made as to the smoothness of the bones and the greater cranial 
elevation as compared with other batrachians of the Carbonifer- 
ous period. This is indicated, among other things, by the 
skulls lying upon one side, which is not found to be the case
