18. SCHLOTHEIMIA COMPTA (Sow.) (Canavarz). 
1882, /Egoceras comptum ; Canavari, Fauna Lias Spezia ; 
Palzont. xxix, Pl. iv (xviii) fig. 5. 
A small specimen 7 mm. diameter, in the Geol. Survey 
Museum, seems near to Canavari’s above-cited figure ; but 
it has rather less coarse ribs. It is from ‘“ Lower Lias, 
Redcar [Yorkshire], Tate Collection,” and is No. 14035 [b]. 
19. SCHLOTHEIMIA MISCELLA (OffeZ) 
Tf. 1844, J. Buckman, Geol. Chelt., xi, 1. (Ammonites 
sulcatus). 
Nom. 1862, Oppel, Pal. Mitth., iii, Jur. Ceph., p. 130, 
(footnote). 
T./._ Vale of Gloucester [near Cheltenham, Midland 
Railway Station. ] 
Wote.—Type refigured, 1904, S. Buckman, Pal. U. 39, 1, 
as Schloth. subrotunda, which becomes synonym. 
Remarks :—Oppel named this species in a footnote. 
The practice of making alterations in nomenclature in 
footnotes is undesirable, because they are so apt to be 
overlooked. That has been the case here. Oppel named 
this and A. rumpens (p. 242) in the same footnote ; but 
neither appeared in Hyatt’s memoir, and A. mzscel/us was 
not noted in Pompeckj’s paper. So Oppel’s naming 
escaped my notice, and I happened to give another name 
to the same fossil. That name must of course drop. 
There is a specimen in the Collection of the Geol. 
Survey, Jermyn Street, No. 14033. It is from “ Lower 
Lias, Badgworth [Gloucestershire], Tate Collection.”
