Believing that 
the Axinus of the 
Magnesian lime- 
stone differs es- 
sentially from the 
Axinus angulatus 
of the London 
clay, Mr. King 
proposes the 
newgenericname 
of Schizodus.

Observations. 
Specimens given 
by M. Geinitz 
have convinced 
us that his Cu- 
cnllcea Schlot- 
eimi had such a 
dental apparatus 
as is seen in the 
Axinus Rossicus, 
nob. 
Identical with the 
Cucullaia sulcata ,

Mr. King pro- 
poses the new 
genus Pleuropho- 
1 for these two 
fossils.

According to Mr. 
King, these two 
shells have two 
well-defined ad- 
ductor muscular 
impressions.
