Key. G. R. Leathes, who obtained it at Roydon ; the 
third, and most regular one, I picked up at Bramerton, 
it is the one figured, and is very tender. 
Being desirous of commemorating Mrs. Cobbold, whose 
copious collection obtained with great industry, in company 
with several of the junior branches of her family, whom she 
delighted to inspire with a love for the works of Nature, 
from the Crag pits of her own estate, evinces a degree of 
taste and zeal seldom met with ; 1 have named this rare, 
and withal elegant shell after her. 
NUCULA lanceolata. 
TAB. CLXXX. — Fig. l. 
Spec. Char. Transversely ovato -lanceolate, smooth; 
posterior side pointed, edge entire ; a concave 
deltoid space in the hinge. 
Sides nearly equal, the anterior being rather the largest 
is most rounded ; the shell is strong, and of almost equal 
thickness throughout, the beaks projecting but slightly : 
length half the width. 
This curious Nucula was discovered by the Rev. G. R. 
Leathes, at Bawdsey, Suffolk, in Crag ; the line of the 
hinge is broken, but not much bent ; nevertheless it has 
the genuine characters of Nucula. It appears to be very 
rare.
