9. On a Goniomya from the Cretaceous Rocks of 
Southern India. 
By H. C. Das-Gurpra. 
Some time ago, with the kind Seno of the Director of 
the Geological Survey of India, I had an opportunity of 
examining some lamellibranchs collected Sy Mr. Foote from 
Southern India. Most of the fossils belong to species already 
ease by Stoliczka.! Among eee there occurs, however, 
a specimen of Goniomya, a genus which had not previously 
been apne amongst the fauna of: Southern India 
Grossouvre*, beds extending downward into the horizon of the 
Gault. The fossil is pointe nted by a cast of the right valve, 
and although poorly preserved, the peculiar sculpturing of the 
valve leaves no room for any doubt as to the generic face 
ation. It belongs to the group of the ovales. Goniom 
ranges from Upper Lias to Cenomanian, the maximum Seesion: 
ment 
times, which period also corresponds with the maximum 
ovales 
development of the The latest form of the group of 
ovales to which i can find any une. is G. (Lystanassa) 
designata, Goldf.’, from the Cenomanian of Westphalia and 
Cleve. The Southern Indian ipeciiany 3 is is wpenitiedlly different, 
but it is not sufficiently well preserved for an exact diagnosis.
