approaches the S. Indian forms of the corrugatus type (Lamarck’s) in 
outline, and is barely distinguishable from two shells in the Asiatic 
Society’s collection, which are labelled from Ceylon. It is a stouter 
shell than the Lamarckian corrugatus.*

This species is barely separable from some varieties of Unio favidens, 
Bs. It is, howeyer, a rounder, thinner shell, forming a link, both in 
character and locality, between that species and Unio corrugatus. 
No. 17.—Unito Wynrcuneaznsis, Lea. Wynegunga river, east of 
Nagpoor.

_ Except in greater thickness, and stouter hinge teeth, there appears 
no distinction of the slightest importance between this “‘ 
species’ and 
the last. The type abounds in the Godavery and its feeders, and 
is, as usual, variable. The locality given by Lea is Wynegunga 
river, Hast of Nagpoor in the Deccan, Bengal, which is equivalent 
to talking of Philadelphia in New England, Virginia. However it is 
hardly fair to expect American naturalists to have accurate information 
on Indian geography, when an English naturalist of repute confounds 
the Khasi hills in N. E. India with the Nilgiris in the S. W., and 
when a second, in a work solely devoted to Indian zoology, perhaps 
the most important work on any branch of Indian Natural History, 
exclusive of botany, ever. published in England, confounds Saharun- 
poor with Serampoor on the Hooghly. After this, the discovery made 
by the Zimes newspaper, a few years ago, that a spur of the Hima- 
layas is visible from Calcutta is not so surprising. <A distinguished 
French naturalist, five or six years since, placed Kattiawar in Cochin 
China, but it is only fair to add that this was before the French expedi- 
tion to the latter country, and that French naturalists have already done 
not a little towards making us better acquainted with the Molluscan 
fauna of that little known region. 
* Since writing the above, I have learned that the locality is correct. The 
shell was collected by Dr, Bacon,
