volution to a level 4 mm. beneath the peripheral angle of the 
latter, and corresponding concealment is shown along the upper 
volutions. Directly over the aperture, the second last volution 
shows a prominent revolving striation two-fifths of the distance 
from the suture above to the peripheral angle beneath, along the 
upper face of the volution. Above and below this revolving 
striation the upper face of the volution is gently concave. No 
trace of this revolving striation can be detected along the last 
half of the last volution. The character of the slit-band on the 
peripheral angle can not be determined beyond the fact that it 
is not broad and deep as in Phanerotrema. On the last volution 
fine striae curve backward from the suture above toward the 
peripheral angle, and on the lower side of this angle they curve 
at first moderately forward, then vertically downward, and finally 
moderately backward toward the umbilicus. Apparently there 
are traces of numerous, fine revolving striae, but these traces are 
so vague that the presence of such revolving striae can not be 
asserted with confidence. Possibly the shell is related to the 
group typified by Lophospira inexpectans, but in that case the 
trilineate character of the slit-band should be in evidence, even 
in a shell whose surface is no better preserved than the one at 
hand. 
Locality and formation.^ — In the loose chert, assumed to be 
of Laurel age, on Jeptha Knob, Kentucky. Named in honor of 
Prof. Walter H. Bucher, of the University of Cincinnati.

Fragments of the cranidium, thorax, and pygidium indicate 
the presence of a large species of Calymene, certainly equalling 
160 mm. and probably equalling 170 mm. in length. It is easily 
comparable in size, therefore, with the large specimens of Caly- 
mene platys Green from the Schoharie grit of New York.
