[Foerste. 
ton, Ohio, and a cast presented to me by Dr. G. M. Austin of that 
city. The specimen is 37 mm. long. It once had probably four 
sides and each one of these sides had a width of 5.7 mm. at the 
smaller end of our specimen and of 12.8 mm. at the larger extrem- 
ity. Towards the base, each of the sides is moderately angulate 
along the median line, these angles apparently becoming obsolete 
towards the larger extremity. Along this median line also the 
transverse striae form an angle of 135°, towards the smaller ex- 
tremity, this angle diminishing towards the larger end, the striae 
becoming almost transverse in a direct line near the top. The 
furrow separating the sides is strong and deep below, growing 
less prominent above in our specimen, but whether this is due to 
distortion or not we do not know. 
There are eight and one-half or nine transverse striae in a length 
of 2 mm. Crossing these striae are much finer longitudinal striae, 
about fifteen in a width of 2 mm. These may usually be detected 
by the unassisted eye, but require a low power lens to be readily 
seen. The longitudinal striae, being almost perpendicular to the 
transverse striae, seem to originate near the median line of each 
side and to pass diagonally towards the furrows ; but towards the 
top of the specimen where the transverse striae are less curved 
near the median line, the longitudinal striae are more in line with 
the longitudinal axis of the shell. The longitudinal striae are 
prominent between the transverse striae, but on the transverse 
striae they form only slight crenulations, these appearing towards 
the larger extremity of the shell as a row of minute dots on the 
transverse striae. 
It has been more than a year since I saw authentic specimens 
of Conularia Niagarensis from the Niagara of New York, but to 
the best of my recollection the Ohio Clinton forms are not distinct 
from the smaller specimens of that species. 
Bellerophon fiscello striatus, Foerste. 
This species was first found at Soldiers’ Home near Dayton, 
Ohio. Two specimens with slightly coarser striae were found at 
Brown’s Quarry, near New Carlisle, Ohio. 
Five specimens were found in our meagre collections from Han- 
over, Indiana, so that it seems to occur there in greater abundance. 
The largest specimen is 13 mm. in diameter and 12.2 mm. wide 
at the mouth.
