The name of N. inflata may he applied to those somewhat 
aberrant forms which have the commencement of the test with or 
without constrictions, but with the later growth more or less inflated. 
Reuss described this species from the Planermergel of Luschitz, 
Bohemia. It is found in the Gault in zone v., very rare ; zone ix., 
rare ; zone xi., 55 ft. from the top, very rare ; 25 ft., rare ; 12 ft.,

This form was originally described from specimens out of the 
Planermergel of Bohemia (Reuss ; also found in the Gault of 
Montcley (Berthelin). The smaller specimen here figured closely 
approaches the form described by Reuss under the name of N. lameb 
losocostata, but which I have included with N. tenuicosta , as there is 
enough evidence in a large series of specimens to show that it is quite 
unnecessary to separate them. N. lamellosocostata has been found in 
the Upper Hils formation, the Speeton Clay, and the Minimus- 
thon of North Germany (Reuss) ; and the Gault of Folkestone 
(Reuss, Rupert Jones). In the Gault of Folkestone it is found in 
zone i., specimen b, frequent; zone iii., rare; zone vi., frequent; 
zone vii., rare ; zone viii., frequent ; zone ix., frequent ; zone x., 
common ; zone xi., 50 ft. from the top, frequent ; 45 ft., frequent ; 
40 ft., very rare ; 35 ft., rare ; 30 ft., rare ; 25 ft., very rare ; 20 ft., 
very rare ; 12 ft., common.
