as in Micrerpeton caudatum Moodie, there occur two definite dark 
lines, one beginning at the tip of the tail and running obliquely along 
the tail to where the impression is broken at the anal region; the other 
beginning at a distance of four and one-half millimeters from the tip 
and running almost parallel with the median line. These two lines 
undoubtedly represent the lateral line system (figs. 5 and 6). 
Fig. 6 A reconstruction of the possible appearance in life of the Coal Measures 
branchiosaurian, Eumicrerpeton parvum, a small primitive salamander less than 
two inches in length. The drawing is based on three well preserved specimens, 
showing impressions of the full form of the body and on the studies of Credner, 
Thevenin, Fritsch, von Ammon and Broili of the European Branchiosauria. The 
lateral line canals are represented as dark bands on the caudal region. The 
sense organs were situated beneath specialized pigmented scales and to these is 
due the preservation of these organs. 
Fraas (13) has described additional cranial portions of new 
labyrinthodonts (fig. 7) from the Triassic of Germany, which 
support and verify his former" findings of the lateral line canals
