REFERENCES TO THE PLATES. 
perience can enable a collector to pronounce on distinctive 
separations between specimens approximating so closely as 
do the present series, and possessing at best, characters 
both obscure and ecpiivocal for specific limitations. One 
other species I will however venture to name beyond the 
present, and that is a sort whose stem seems to be quite 
simple and whose head resembles greatly in figure the 
Lepas anatifera. Mr. Peach has a specimen also from 
the Van in his neighbourhood, which is probably a Penta- 
crinite. Table 8 presents a view of a Spatangus from the 
limestone of Ashburton, procured by Mr. G. Bartlett, and 
here introduced because it is the only one that has been 
obtained from our limestone. Table 9 is a species of 
Anancliytes from the walls of one of the celebrated ossife¬ 
rous limestone fissures of Oreston, but which I have also 
had from the limestone of Plymouth Hoe ; it is introduced 
from being as yet unknown to geologists. Table 10 recurs 
to the encrinital remains of the grauwacke series, and is 
devoted to the more conspicuous and evidently distinct 
species from Whitsand Bay grey sandstone, and from that 
which is similar at Boveysand on the opposite side of the 
harbour. Fig. 1 is a joint having a very flat surface, cu¬ 
riously divided by white lines passing from the centre. Fig. 2 
is a series of joints from Boveysand, and these like a sort 
before named have oblique lines on their rims. Figs. 3 & 4 
are series of joints apparently different from all others, and 
finally. Fig. 5 is an elegant fossil vertebra of the same order, 
distinct in general shape, and by its surface sloping to the 
central opening, with fine lines arranged as radii. 
I have only to note in conclusion that the slate fossils both 
from the south-east and north of Devon and from Cornwall 
are very analogous to those in South Devon, and altogether 
indicate that the same series extends itself around us. The 
old red sandstone also of the coast is continued from the 
south of Devon most regularly onwards into Cornwall 
taking a westerly direction, and betrays along its course 
the presence of those genera of animal remains which con¬ 
firm it as a member of the grauwacke order.
