THE FLORA OF WARWICKSHIRE.

sub-triangular in shape, and has a foreshortened appearance, 
as if it had found life a struggle, but had tried to make the 
best of it. This Myophoria, with the allied form Schizodus , are 
common in the Musclielkalk, and in the Keuper of Germany. 
Perhaps the most notable feature of the Lamellibranchs obtained 
near Warwick, is the peculiar reticulated ribs upon the valves of 
many of the specimens. These striae cross at an acute angle, 
forming V’s to the anterior and posterior Inargin of the valves ; 
this is noticeable even in small fragments, and is characteristic of 
the genus Goniomya. Many of the specimens show striae, passing 
from the umbo to the margins of the shell ; but so fragmentary 
are the fossils, and so many of the component parts (the cardinal 
teeth, &c.) are missing, that it is impossible as yet to assign, with 
certainty, these Warwickshire shells to their proper place. 
The specimens so far obtained have come from a little disused 
stone-quarry and marl-pit at Shrewley, near Rowington. They 
were discovered by Mr. Richards, son of the borough surveyor for 
Warwick. The sandstone in which the casts of the shells occur 
probably belongs to the Upper Keuper; but its precise horizon in 
that division of the Trias is somewhat uncertain and variable.
