AUG. F. FOERSTE 
vertical striae rarely are shown. Possibly most specimens lack- 
ing these vertical striae are casts of the interior of the shell. 
Found at Buford Cave, 2 miles west of New London, near the 
top of the Plattin limestone. 
28. Hyolithes miseneri Foerste 
Under, the name Conularia miseneri the writer described a 
'series of specimens from the Whitewater member of the Rich- 
mond at Richmond, Indiana (Journal of Cincinnati Soc. Nat. 
Hist., 22, 1917, p. 42, pi. I, figs. 1 A, B, C). Later it was recog- 
nized that the supposed Conularia was the convex side of a 
species of Hyolithes, the median part of which was elevated as 
in the second specimen of Hyolithes haconi, described in the pre- 
ceding lines. The transverse striae are more prominent. Along 
the median line of the shell they curve slightly downward; 
laterally they curve rnore strongly downward as far as the lateral 
sides of the shell where they begin to curve rapidly upward. 
From this it is assumed that on the flattened side of the shell the 
transverse striae curve strongly upward as in other species of 
Hyolithes. The vertical striae are finer but distinct. An almost 
identical species occurs in the Kimmswick of southern Missouri. 
29. Orthoceras with vertical color bands. 
In a specimen of an unknown species of Orthoceras found at 
the top of the Plattin limestone at Conn’s Ford, vertical color 
banding is present. The specimen is 22 mm. in width. The 
color bands equal or slightly exceed 1 mm. in width and are 
1 mm. or slightly less apart. The color banding is a feature 
characteristic of the inner layers of the shell and is seen best 
where the surface of the shell has weathered away. 
Orthoceroid shells with vertical color bands are known also 
at other horizons. In the Lorraine formation in the river bed 
west of Weston, Ontario, vertical color bands occur in an Ortho- 
ceroid shell 22 mm. wide, having a siphuncle with nearly spheri- 
cal segments (Loxoceras ?). About 8 vertical color bands occur 
in a width of 5 mm., the width of the color bands and that of the 
intervals between being about the same.
