5. SCHLOTHEIMIA GALLICA, nom. nov. 
1844, Ammonites catenatus; d’Orbigny (non Sowerby), 
Pal. frang., Ceph., Pl. xciv, figs. 1, 2 only. 
As dOrbigny’s specimen does not agree in any way with 
Sowerby’s species, a new name is necessary. Its ribs 
are more approximate and less distinct than in either SS. 
acutecosta or S. prometheus; and its periphery is much 
smoother. 
A fragment submitted by Mr Tutcher, last septal cham- 
bers and beginning of body-chamber of a specimen about 
165 mm. diameter, agrees well with d’Orbigny’s figures. 
It shows suture-line with very short lobes and wide, 
shallow saddles—very simple in comparison with that 
shewn in Pl. XI, f. 7. 
6. SCHLOTHEIMIA ANGULATA (Schlothetm) 
Wahner,* Hyatt* and Pompeckj? agree that the figures 
given by Wright CZ goceras angulatum, PI. xiv, figs. 5, 6, 
Monogr. Lias Amm.) represent Schlotheim’s species. 
7. SCHLOTHEIMIA COLUBRATA (Schlotheim-Zieten) 
Hyatt says that the figures given by Wright, Mon. Lias 
Amm., Pl. xvii, figs. 1, 2, “ A®goceras angulatus= Am- 
monites Moreanus, d’Orbigny,” represent Am. colubratus. 
Certainly they closely resemble Zieten’s figure.
