CUCULLJEA minuta. 
TAB. CCCCXLVIl.-^. 3. 
Spec. Char. Elongated-ovate, convex, striated, 
anteriorly submucronated ; anterior lobe 
small, separated by a keel; beaks nearly 
close. 
Rather more than twice as wide as long, and smallest 
at the extremities ; the ridge that defines the anterior 
lobe forms a projecting angle upon the margin ; the 
anterior side is very obliquely truncated ; the valves are 
rather flat. 
Found along with a great number of small and even 
minute shells, among which are the Pileoli (tab. 432.) in 
limestone at Ancliff, by the Rev. George Cookson. Many 
of the shells that accompany it appear at first sight to be 
the young of larger species, but upon a careful exami- 
nation they will perhaps prove as distinct as the one 
before us. 
CUCULLiEA rudis. 
TAB. CCCCXLVII .—fig. 4. 
Spec. Char. Transversely oblong, convex, 
rugged and longitudinally ribbed; beaks 
incurved, nearly close together ; anterior 
lobe not defined. 
JLiarge rugose ridges occupy both sides of this shell, the 
middle is deeply striated ; the anterior side is not dis- 
tinguishable from the middle portion of the valve. 
A very imperfect specimen, but the only one we have 
seen ; it is in the Rev. Mr. Cookson’s suite of Shells found 
in the limestone at Ancliff. We are happy to have it in 
our power thus to acknowledge our thankfulness for the 
loan of the whole collection for examination ; it is very 
remarkable for the great number of species of Shells, 
Corals and Crinoidea it contains.
