Remnrks. — Thi.s species is clu.sely allied to /. loliatns, Goldfuss, but the speci- 

 mens at present available are not sufficiently perfect to enable me to make a close 

 comparison. /. liiiffiia appears to differ from /. lobatu.^ in the absence of the ridge 

 between the umbo and tlie postero-ventral angle, in the absence or indistinct 

 character of the radial depression in front of the ridge, in the greater relative 

 length of the shell, and in the ribs being either of uniform size or of two sizes less 

 distinctly niiirked than in 1. lubninsi. 



Type. — From the Senonian of Diilmen. 



Distribution. — Upper Clialk of Birdsall, Yorkshire. Zone of Bclemititelln
