ciated with Cad. raricostatum, and therefore, according to our classification, are in 
the Lower Lias. Oxyn. Oppeli and numismale survived-in the Middle Lias of 
Germany, Oxyn. Oppeli alone in the basin of the Rhone, and Oayn. numismale 
alone in England. 
FaAuNA OF SoutH GERMANY. — TABLE I. 
The notable facts brought out by this table are the following. The abundance 
and concentration of schlotheimian forms in the Angulatus zone, and their early 
appearance in the Rhetic. The completeness of the Caloceran series in the 
lower horizons, and the poverty of the faunas existing between the Geometricus 
or Upper Bucklandi beds and the Raricostatus bed in respect to these series, and 
also in the vermiceran, arnioceran, and coroniceran series. The asteroceran series 
reached a high stage of development as regards the number of forms, but is not 
represented by the extreme modifications noticeable in the basin of the Rhone. 
The oxynoticeran series is also present, and even passes into the Middle Lias, but 
has not a full representation of species. 
FAUNA OF THE COTE pD’OR. — Tassie II. 
The Ammonites at Semur were named by M. Reynés, and these names have 
come into circulation through publication by M. Collenot in his “ Description 
Géologique de lAuxois,” and have also been quoted by Zittel and several other 
authors. Reynés considers many well-marked varieties to be distinct species. 
This is our principal disagreement with this author, and the following notes, 
together with the descriptions of species and table, sufficiently explain other 
differences of opinion. 
Terquem’s figures of Hettangensis! show a keeled, broad caloceran form with 
pile in the young, which belongs somewhere between Cul. daqueum and raricosta- 
tum. ‘The specimens in the Museum at Semur, identified as Hetlangensis by 
Reynés, do not agree with these figures. The specimens identified as Dedmast 
belong to several species, and one of these is so exactly like Pirondi, as figured 
by Reynés in his unpublished plates, that I have quoted this name as a synonym 
for Johnston in the table. 
With regard to the vermiceran series, we traced the relations as follows. 
Beginning with spiratissimum, the forms appear to grade into Schlenbachi, which 
represents Conybeari in the Scipionis bed, then into rotator, which is a close ally, if 
not identical with Amm. caprotinus, D’Orb., and also with the spinous varieties of 
Conybeart found in Germany. The simpler ribbed forms grade into conybearoides, 
Rey., which is not very far removed from syratissimum, thence into true Conybeari, 
and thence into Breom, which last is a stouter and more robust form. Breoni, 
Rey., exactly agrees with typical Conybeari, and also with German forms of the 
same name, whereas Conybeari, Rey., is equal to our Bonnardi. Bochardi, Rey., has 
the form and characters of Conybeari during its earlier and adolescent stages, but
