SUPPLEMENT.— PSEUDOGRAMMOCERAS. cliii 



more distant ribbed fossil than Bayle's G. fallaciosum. It is also presumably a 

 rather thicker fossil than his ; but on this point Bayle gives little opportunity for 

 judgment. 



Localities and Stratum. — Gloucestershire: Little Sodbury, in sandstone. Wright 

 quotes his specimen from Frocester Hill. 



Species not showing Septicarina. 



The suture line particularly indicates that the following species are closely 

 related to Pseudogrammoceras ; radial line and general appearance support it. But 

 they lack the septicarina. This may be due to degeneration, but such degeneration 

 in the costate stage is unusual. 



The radial line and the more lobate suture line separate this series from 

 < IraiiuittK'ei'us.

Remarks. — Denckmann's fig. 4, in his PL viii, may be taken as the type; his 

 fig. 5 is distinctly coarser ribbed.

Description. — Substeno-subleptogyral, perlatumbilicate ; parvicostate to si rim.'. 

 Immature example (PI. XXXIII, figs. 11, 12) — Subplaty-subleptogyral ; latumbili-
