from the Beech River formation and the Waldron shale at Newsom have yielded exception- 
ally fine material of already known species, some of which I am illustrating with new figures, 
where the characters are better shown than in the originals. Several of the leading forms are 
so amply treated in the published accounts that further attention is not needed. A full list 
of the species with their references is given in Bassler’s Index. This genus is remarkable for 
the absolute uniformity of its cup plates. In all the numerous species there is scarcely a 
variation from the number, form and distribution of the plates as above stated.

The colony of the Waldron shale at Newsom seems to have been particu- 
larly favorable to the growth of this and the succeeding species, they having- 
attained a size unprecedented in the genus. I figure here two calices far exceed- 
ing those from the type locality, and in which the pustulose ornament in two 
styles is wonderfully sharp, and the calyx plates are delineated with the clarity 
of a diagram.

This figure of a cup 75 mm. in diameter is given to show the maximum 
size that may be attained by the genus. It is not an isolated example, as the 
species is typically large, with cup low, broad and smooth, and specimens are 
not uncommon of approximately the dimensions of this. It is abundant in the 
Waldron beds at Newsom, and a characteristic fossil of them, not having been 
found at the Indiana localities, although it is reported from the Racine dolomite 
of the Chicago area. For the opposite extreme in size reference should be had 
to E. avails, of which some specimens are less than 5 mm. in diameter, and which 
rarely exceed 10 or 12 mm. (see N. A. Crin. Cam., pi. 82, fig. 4).

A rare species, which was unknown to collectors from the time of Troost, 
who exhibited in 1849 what he rightly called a magnificent specimen under the
