INFERIOR OOLITE AMMONITES. 
Moorei. It struck me that the words "My Collection," which occur in the 
explanation of Plate LXXX, figs. 1 — 3, in the ' Monograph of the Lias Ammonites,' 
might have been written by accident. In answer to my inquiries, Mr. E. T. 
Newton, F.G.S., of the Museum of Practical Geology, wrote that " we have 
always been under the impression that the specimen VI-4-8-, figured by Dr. Lycett, 
was refigured by Dr. Wright ; but on comparing the specimen with the figures I 
find that, although the agreement in size and character is exact, there are points 
about the mouth which differ." Mr. G. C. Crick, F.G.S., of the British Museum, 
informs me that no specimen answering to Dr. Wright's figures was met with in 
the collection of the type specimens of " the Lias Ammonites " which the British 
Museum obtained from a dealer after that gentleman's death. Such is the 
evidence obtainable ; but it is only right to remark that, as the whole of Dr. 
Wright's Collection was not acquired by the British Museum, it is possible the 
figured specimen may have been lost sight of. In any case, for all practical 
purposes. Dr. Wright's figures may be considered as a representation of Dr. 
Lycett's original specimen ; and this is an important matter, for the figure of the 
latter author is so much reduced as to be misleading. Dr. Wright's figures agree 
exactly in size with Dr. Lycett's specimen, but differ in the following trivial points, 
viz. that the lower ventral area is too acute, the mouth a trifle too compressed 
at top, and the ribs of the inner whorls not coarse enough. 
I have the following notes made from an examination of Lycett's original 
specimen : — " In the inner whorls the ribs are coarse and somewhat wide apart, 
while the whorls themselves are slightly gibbous. The outer whorls are nearly 
flat, and the radii become much finer until on the end of the body-chamber they 
are merely very fine growth-lines. The radii are very little curved on the lateral 
area, and not much curved forwards on the ventral area. (Lycett's description 
diS'ers from this, but he probably had specimens of Burn. Moorei and Ch^amm. 
madra mixed together : his figure is correct.) The carina is little more than a 
sharpening of the ventral area. It is continued on to the body-chamber." 
It was in 1857 that Lycett named this species Am. Moorei, in compliment to 
Charles Moore, F.G.S. ; but the same name was used by Oppel (' Juraformation,' 
p. 476) in the same year. I do not know which species has priority ; but it makes 
no difference now, as Oppel's species belongs to the genus Perisphindes. 
In 1874, however, Dumortier recognising the difficulty, and considering that 
Lycett's Am. Moorei and what he figured as Am. madra (see p. 176) were identical, 
superseded the name J.m. Moorei by that of Am. madra (' Bassin Rhone,' iv, p. 25.2). 
In 1879 Branco gave an excellent figure of Am. Moorei under the name Harpo- 
ceras madra, and he quoted Lycett's figure as a synonym. 
In 1884 Wright figured Am. Moorei under the name Harp, aaleiise (Zieten). 
In 1885 Haug placed A^n. Moorei, Lycett, as a synonym of Am. madra, Dumortier,
