TROCHUS fascia tus. 
TAB. GCXX. — Fig. i. 
Spec. Char. Conical, umbiiicate, decussato-stri- 
ated ; volutions slightly convex, with a band 
around their middle ; base flattish ; aperture 
quadrangular. 
The width of the base is equal to the height; the 
transverse striae, or rather ridges, are the most promi- 
nent ; the longitudinal ones diverge from the central 
band both ways : the columella seems to have a single 
plait along it, and is tubular. 
In G, W. Braikenridge, Esq.’s cabinet : found in the 
inferior Oolite at Dundry. 
TROCHUS granulatus, 
TAB. CC XX.— F/g. 2. 
Spec. Char. Conical, very short, granulated, 
whorls rather convex above, with a band 
along the middle ; base convex, in part nearly 
smooth. 
The granulated surface is the result of decussating 
furrows, which vary in depth and number in different 
individuals ; they are generally deepest near the margin: 
the height is about half the width : it appears to have a 
small umbilicus, which probably led Mr. Miller to con- 
sider it an Euomphalus, from which the columella and 
left lip of the aperture clearly distinguish it. 
In Mr. Miller’s cabinet ; from Dundry.
