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. Derbyi, 

 from the Carboniferous beds of the Salt-Range of India; 0. ? Morganiana is 

 from the Coal Measures of Itaitiiba, Brazil.
