SANGUINOLARIA. 
Gen. Char. A transverse equivalved bivalve., su- 
perior margin arched, sides slightly gaping ; 
hinge with two approximating teeth in each 
valve, and an external cartilage. 
This genus forms a link connecting Solen with Tellina; 
it contains shells whose hinge is analogous to that of 
some Solens, but in general form they differ much, re- 
sembling Tellina in their flatness and rounded margin, 
but are generally wider. They have been happily se- 
lected from among the Solens of Linnaeus by Lamarcke. 
SANGUINOLARIA Hollowaysii. 
TAB. CLIX. 
Spec. Char. Depressed, transversely elongate, 
ovate, and striated ; anterior side gradually 
expanded ; posterior side very small. 
Length equal to three and a half times its width ; the 
lines of growth form fine sharpish striae ; the beak is 
minute, from it a slight depression extends towards the 
anterior side : the shell is thin. 
This was gathered at Bricklesome Bay by the friendly 
Mr. Holloway, whose name I feel pleased to com- 
memorate, four or five years since : although it is 
rather an abundant species it is rare to find one indivi- 
dual at all perfect : the pair figured here are held toge- 
ther by green sand ; they are brittle : one shell is perfect, 
the other has been partly broken away so as to shew the 
hinge, and but little more is seen : it will readily be re- 
cognized if found again, and is at any rate a valuable 
addition to the catalogue of British fossil shells.
