diviso. 
A suhpcntagonal or clongatcly ovate shell, with the two valves almost equally 
strongly convex. The surface is covered with fine, equal, and very densely set gra- 
nules, when Avcll preserved ; hut when it is a little worn off, the granulations appear 
to he arranged in finely undulating rows. The hmmal valve is anteriorly somewhat 
depressed, posteriorly rounded ; the septum equals in length about f of that of 
the shell. Of the brachial apparatus I could trace only fragments on ditferent 
sections of the valve, but it could be seen that it closely resembles that of 
Kingena lima, the neural reflected portion being very broad and mcetmg the 
septum under a rather small angle. 
The hsemal valve is most convex along the middle of its entire length, and is 
laterally considerably depressed. The beak is slightly incurved, with a large dilated 
rounded foramen in front. The dcltidium is always in two pieces, each of which 
is elongatcly triangular. The beak ridges are very strongly developed and sharp, 
peculiarly bent upwards as they approach the foramen, the consequence being that 
the beak appears to be very truncate ; while, if the lower portion of the ridges were 
regularly prolonged, they Avould meet at the beak under an angle of about 95 degrees. 
K. gramdifera is readily distinguished from AT- lima by the anterior median de- 
pression of the haemal valve, more prominent and less incurved beak, and by stronger 
umbonal ridges. The general form itself comes nearest to the varieties of K. lima, 
figured by Deslongchamps in Bull. Soc. Norm., 1861-G2, vol. vii, pi. viii, and 
also by Schloenbach in Sitzb. Akad., Wien, vol. Iviii, p. 212, pi. iii, figs. 1 — 2, but 
it separates it equally readily from King, tamarindiis, which has the dcltidium gener- 
ally united in the median line. As regards the shape of the beak and the dense 
granulation, K. gramdifera is probably more closely allied to the tertiary K. Bain- 
courti, than to any of the cretaceous species (Deslongchamps in Bull. Soc. 
Norm., vii, p. 291, pi. viii, figs. 12 — 11).

The only specimen in our collection from Southern India is a very imperfect 
one, but the comparison of numerous Eiwopean specimens makes, I think, the 
identification certain. The form is roundly ovate, the hoemal 5 al\ e less con\ ex 
than the neural one, the former being in the middle of the front slightly depressed;
