of the Jumna at Humeerpore in Bundelkhund, being left in the mud on 
the subsidence of that river. The first which was procured was very 
small, and was the most recent specimen met with, the valves being 
connected by the ligament, and traces of the epidermis being visible. 
Repeated searches failed to procure me more recent specimens, or any 
other than a single valve of a larger size. 
In 1830, I procured several single valves from the sandy bed of the 
river Cane, under the fort of Bhooraghur, near Banda, Southern Divi- 
sion of Bundelkhund. 
The form of the shell, its lozenge-shaped ligamental scar, and the 
position and order of its teeth shew its place to be among the Arcacee: 
while the oblique production of the teeth on the posterior side down the 
inner surface of the cardinal lamina, the separation of the teeth into two 
sets by the interposition of an edentate portion of the cardinal lamina, 
and the freedom of the shell from ribs, with the exception of the ridges 
which occur at the angle of the shell, will suffice to distinguish our shell 
from the genus Arca, which will still comprehend marine shells only. 
The term Scaphula, while it expresses its diminutive size in com- 
parison with some of the gigantic species of Arca, will serve to point 
out its affinity to that genus, and may perhaps be adopted to distinguish 
the genus should a better one not have been already proposed.

Tue possibility of importing from other countries, and especially 
from the warmer latitudes, the animals which construct the innumerable 
testaceous productions that adorn our cabinets and museums, the accu- 
rate knowledge of which is so necessary to enable the conchologist 
rightly to arrange this beautiful department of nature, must be an in- 
teresting subject to every naturalist, and will render no apology neces- 
sary for the following notices extracted from my Journal. Their 
publicity may incite others who may have opportunities of trying the 
experiment to follow the example.
