INFERIOR OOLITE AMMONITES. 



Correction.— In the explanation of PI. XXIT, figs. 32, 33, and PL XXIII, 

 fig. 1, erase the word Lillia. The species does not belong to the Hildoceratidas, 

 but to the Sonnininse, a sub-family of the Affialtheidae. Hang lias more correctly 

 called the species Sonninia sulcata ; ] but its removal from Sonninia will become 

 necessary. Consequently make the necessary corrections in the text at p. 109. 



1. Lillia Lilli, Hauer. Suppl., Plate I, figs. 1 — 6. 



18-36. Ammonites Lilli, Hauer, PI. viii, fiys. 1 — 3. 



(Non Am. Lilli, Dumortier; non Lillia Lilli, Bavie.) 



Description. — Stenogyrai, latumbilicate, subornate, nodate, sparsi-subrursi- 

 recticostate, septicarinate, subpauciseptate, inornatilobate. 



Remarks. — The rursicostate character is shown in Hauer's figure with so much 

 want of uniformity as to suggest a possible incorrectness on the part of the 

 artist. If, however, the character does exist as delineated, then our specimen 

 does not agree with Hauer's in this respect, for it is only subrursicostate, in 

 which case it may be wrong to give it the name of Lilli. 



Localities and Stratum. — Somerset : Shepton Beauchamp ; and Trent, near 

 Yeovil, " Upper Lias" (in close connection with Hildoceras bifrons). 



Late of Existence. — Lilli hemera. 



2. Lillia nakbonensis, S. Buckman. Suppl., Plate II, figs. 3, 4. 



1874. Ammonites Lilli, Dumortier (non Hauer), Pt. 4, pi. xxi. 



Description. — Stenogyrai, latumbilicate, subornate, nodate, subdensi-subrursi- 

 recticostate, septicarinate (?). 



Remarks. — The description is drawn up from Dumortier's figure. It may be 

 presumed by analogy with other species that this one is septicarinate, and that 

 the representation of the carina in Dumortier's figure is incorrect, the remains of 

 the infilling being drawn as a complete carina. 



The name narbonensis is taken from the appellation of the Roman province in 

 which Dumortier's specimens were obtained.
