cular scars as in Schizophoria. Although Dr. Derby emphasizes the latter feat¬ 
ure as of especial importance on account of its being composed of three pairs 
of scars, it has been shown that this area in Schizophoria is of the same char¬ 
acter when distinctly defined, a condition not often observed. (See Orthis 
impressa,, Plate VI a, fig. 28.) 
Orthis ? Morganiana apparently represents a passage-form between Schizophoria 
and Enteletes, though its predominant characters are distinctly orthoid.* 
Dr. Waagen refers to the same group his species, Orthis marmorea and 0. Derhyi, 
from the Carboniferous beds of the Salt-Range of India; 0. ? Morganiana is 
from the Coal Measures of Itaituba, Brazil.
