Hadrophyllum linguloideum, sp. nov. 
CPiate. Wl salient: ) 
Corallum free, exceedingly flat or short, ovid-linguloid, 
transverse diameter 1 3-16 in. and in direction of the large 
septal fossula over 1 in. long. Calicle superficial, posterior 
margin slightly raised, with a central fossula and two smaller 
ones, diverging from each other at almost right angle from 
the apex of the former and forming two acute angles on 
the calicle. Posteriorly it has 50 radiating septa, necessarily 
dividing toward an enlarged periphery. The interior part 
of the calicle has between each department of fossule 12 
septa. This species is the largest in its genus. Shell-like 
it begins its growth most laterally and adding concentri- 
cally to the interior parts, so as to give the corallum with 
its perfect epitheca and rings of growth the appearance 
of a very large lingula being thick at the most lateral pos- 
terior apex and thinning out toward the front. —Cornifer-

Cyathophyllum capax, sp. nov. 
(Eilate waxy Jetson 7123) 
Corallum simple, rapidly expanding, very ventricose 
to the anterior, slightly concave posteriorly; length 2 in.; 
calyx 2 in. across, laterally a little wider, posterior side oval 
and from side fossettes obliquely meeting the main fossette 
at right angle; depth 3in., walls thick, composed of 120 
lamellae, which are not prominent, causing a smoot inter- 
ior; main lamellz crossing the floor, which forms an im- 
bossment, through which a deep broad fossette passes, 
leaving a spaciousness of the floor of 14 inch. — Corni- 
ferous Limestone, Columbus, Ohio. 
Zaphrentis Neptun, sp. nov. 
GPiate mere ts “Plate Ide . Fig. 137) 
Corallum simple, erect, cylindrical, smooth with slight 
undulations and fine concentric rugz in its epithelial coating.
