XXX.— A Description of, and Remarks upon, some Fossil 
Corals from Sinde. By P. Martin Duncan, M.B. Lond., 
F.G.S. &e. 
[Plates XVIII. & XIX.] 
Ir must be evident to all who have studied the distribution of 
the Corals of the Secondary and Tertiary formations, that the 
Eocene Coral-Fauna is very poor in genera, and that it is much 
less important than those of the lower Cretaceous and the Miocene 
strata. The comparative scarcity of Eocene Corals rendered 
M. J. Haime’s description of seventeen species from the Num- 
mulitic formation of Sinde of great interest, especially as several 
of them were well known in the French and Savoyard Nummu- 
litic strata, and also because a new genus was added to the 
fauna*. Since the decease of this gifted naturalist, a part of 
the Blagrove Collection belonging to the Geological Society of 
London has remained undescribed}; and a very fine series of 
Corals from Kurrachee, in the British Museum, also. I was 
tempted to search for new forms, and found many more than I 
had anticipated; but all of them are not of Eocene age. MM. 
d’Archiac and J. Haime appear to ignore the Miocene in the 
great chain of hills which extends from the “ Salt range” almost 
due south to Kurrachee; but the memoir written by Grant f, 
and illustrated by Sowerby, strongly advocates the existence of 
more than one Tertiary formation of marine origin. The dis- 
covery of three fossils from Kurrachee identical in species with 
common forms of the Nivajé shale of San Domingo leaves no 
doubt in my mind that several of the species about to be noticed 
ought to be separated from the Eocene Coral-fauna. 
The following list embraces all the species as yet found in 
Sinde ; and I have appended the other localities where they have 
been observed. The species which came under M. J. Haime’s 
observation are also noticed.
