LIMA proboscidea* 
TAB. CCLXIV. 
Sf. Char, Broad, ovate, convex, with twelve ribs, 
each furnished with several large tubular 
processes ; ears small. 
The tubular processes are thicker than the ribs they 
arise from ; they are an inch or more long, variously 
bent and pressed to the shell $ their ends are often ex- 
panded, they are nearly alike on both valves ; the ribs 
are large and smooth, except a few rudiments of proces- 
ses here and there . The length is to the width as three 
to two nearly, the depth is not considerable. 
Single valves of this shell, without the hinge, might 
be taken for Spondili, but the similarity of the two valves, 
and the opening between them on one side seem to con- 
firm the idea of its belonging to the genus Lima ; yet as 
we have not seen the inside of the hinge we may be de- 
ceived, and it may prove to be a new genus. 
The larger figure is taken from a specimen lent me by 
the Rev, W . Buckland, it was found near Weymouth ; 
the lesser one is from the same place.
