Represented by two or three fragments. 
Ortlioceras^ sp. 
A fragment partly buried in the matrix appears to belong to a 
species not before met with in the German Devonian rocks. 
The sculpture consists of transverse imbricating striae, about 4 to 
1 line, and these are covered by very line lines parallel to the 
imbrications. The latter require rather a stroug lens to make them 
visible. 
Barrande has described a species from the Silurian rocks of 
Bohemia (Etage E), to which he has given the name of 0. conso- 
hcinum \ which has similar sculpture to the present form ; but as 
that is the only character available in the latter for purposes of 
identification, I do not feel justified in uniting it with Barrande's 
species.

Fairly well represented. Also in the Silurian.

Remarl's. This species appears to be known only by a fragment 
the characters of which are scarcely sufficient to my mind to sepa- 
rate it from other forms having similar sculpture. The latter 
consists of fine raised lines, about seven in the space of 1 line, and 
very oblique to the long axis of the shell. The rate of tapering 
cannot be ascertained. The siphuucle is subcentral.
