LINGULIDA. 4] 
Length of a large example 20, breadth 14 lines. 
Obs. This shell is very variable in its outline, as may be seen from the figures in 
our plate, several of which were taken from the original specimens illustrated by Phillips. 
It is also one of our largest species of Lingula. Although not exceedingly rare in the 
Upper Llandovery of Howler’s Heath, in the Malvern district, no bivalve example has, 
to my knowledge, been hitherto collected. When young, some specimens resemble 
L. attenuatag but adult examples can always be readily distinguished from the latter. 
LI. crumena occurs in the Pentamerus-conglomerate at Kinley, Shropshire. (Museum of 
the Geological Survey.)

Although briefly described by Dr. Holl as “ triangular, broad anteriorly, compressed ; 
beak acute; anterior margin truncate; shell thick, strongly grooved from side to side by 
imbricating lines of growth; length quarter inch,’ no specimen was entire enough to 
enable the author to figure his shell; and, consequently, on such incomplete and unsatis- 
factory material not much can be said either as to its characters or specific value. In my 
plate I have ventured to give a slightly restored representation of the shell, taken from 
one or two of Dr. Holl’s fragmentary specimens, and which indeed strongly reminds us of 
certain young examples of Lingula cuneata, Conrad (Hall, ‘ Pal. of New York,’ vol. il, 
p- 8, pl. iv, fig. 2). LZ. squamosa is stated by Dr. Holl to occur in the light-brown felspathic 
Hollybush sandstone in the Malvern Hills; and he agrees with Mr. Salter in considering 
this sandstone to be equivalent to the middle division of the Lingula-beds of North Wales.

1 A point of interrogation placed before the specific name, as above, will indicate that some un- 
certainty as to the value of the species is entertained by the author of this Monograph, or that its characters 
have not been sufficiently determined.
