TROCHUS punctatus. 
TAR. CXCIIL —Fig. 1 . 
Spec. Char, Conical, with straight sides, trans- 
versely striated ; upper striae upon each whorl 
crossed by oblique undulations, lower ones 
minutely granulated, a narrow band between 
the two sets, 
Very little higher than wide : the surface is tolerably 
even : the striae are numerous ; they are most prominent 
towards the upper parts of the whorls, where they are 
granulated by small oblique undulations : towards the 
apex the band is crossed by fine stria?. 
From the inferior Oolite of Dundry, near Bristol. 
TROCHUS elongatus. 
TAB. CXCIIL — Figs. 2, 3 and 4. 
Spec. Char. Conical, elongated, transversely stri- 
ated ; striae near the apex granulated ; each 
whorl slightly undulated near the upper edge, 
with an obscure band below the middle ; the 
inferior margin prominent. 
Breadth of the base two-thirds the height; the strias 
are less numerous, and the undulations larger but shorter 
than in the preceding : the sides of the whorls are 
slightly concave. 
Very nearly allied to the preceding, but distinguished 
by the prominent margins of the whorls, and longer form. 
Found in the same stratum at Dundry. Mr. Braiken- 
ridge has in his cabinet a specimen 2f inches high, and 
two inches wide, being rather a broad variety.
