BRACHIOPOD SHELLS. 
27 
The shell about once and a half as long as wide; sides parallel 
(or very gently curved) for two-thirds their length, and thence 
sloping backwards to the apex with straight edges (the apical 
angle about 40°). The front is very straight, and angular at 
the corners. The interior is cosely striated lengthwise over 
the long triangular central area. 
It is very difficult to gave characters for species of this 
genus, even from perfect specimens, that shall distinguish 
them. Ours is very imperfect. Enough remains, however, to 
show that it is, like L. attenuata , a British species, which, 
however, is not so flat, has not the centre depressed, and does 
not show the strong longitudinal striation internally. 
Locality .—Kalajowar (15,800) named from the goddess 
Kali (intense nigra). (No. 1758.) 
LINGULA ANCYLOIDES. 
Plate 3, fig. 2. 
L. parva, tertiam partem unciae sequans, eonvexa, regulariter 
elliptica, sfcriis coneentricis coufertis lineata, intus (?)• 
Smaller than the last, elliptical, regularly convex • length 
rather more than once and a half the width. Surface crowded 
with very fine close lines of growth. Interior—? 
If the last species was very imperfect, this is still more so. 
We cannot see the retral or beak end, and the interior is not 
visible distinctly. The surface is finely striated concentrically, 
and there is scarcely any trace of radiating lines of any 
kind. 
The little river Ancylus a good deal resembles this elliptic 
species. The form is rather a common one in the genus : L. 
elliptica^ Phill., and L. mytiloidcs , Sby., of the carbonifeious 
rocks, are both of them like it. 
Locality .—Damchen (16,500 feet). (No. 1678.)
