containing Animal Remains in the Coal Formation of Nova Scotia. 
Phil. Tr clxxiii. pp. 621-646, pis. xxxix.-xlvii. 
The Vertebrate animals in the twenty-four trees ( Sigillarice ) extracted 
belong to the Order Stegocephala , and represent 12 species, of which 2 
are of a doubtful character, owing to the imperfection of their remains. 
The Labyrinthodonta are represented by the genus Dendrerpeton with 2 
species ; the other forms are referable to the Microsauria, and fall into 
5 genera, viz.: — Hylonomus , Dawson (4 species), Smilerpeton , Dawson 
(1 sp.), IJylerpeton , Owen (2 sp.), Frilschia , Dawson (1 sp.), and 
Amblyodon, Dawson (1 sp.). References follow : —

Smilerpeton, g. n., distinguished from Hylonomus by the form of the

Fritschia , g. n., differing from Hylerpeton in the absence of palatal 
teeth, and in the abdominal armour, which consists of long slender rods 
instead of scales. F. curtidentata , sp. n., p. 641, pi. xliii. figs. 110-128.
