NAUTILOIDEA. 
Horizon. Stringocephalen-Kalk (? =Goslarcr Schiefer) ; Middle 
Devonian. 
Locality. Buntenbock, North-west Hartz. 
Represented a very imperfect specimen. 
Orthoceras, sp. 
(Cf. Orthoceratites y7'egarius,'^l\vo&i&t,'^eitY. z. Petreiact. Heftiii. p. 07 ; 
non Sowerby.) 
Two specimens with rather approximate septa, central si ph uncle, 
and portions of the body-chamber are too imperfect for specific 
determination. 
Horizon. Eifelien ; Middle Devonian. 
Locality. Eifel. 
Orthoceras, sp. 
{Ante, p. 59.) 
(Of. Orthoceras suhannulare, Miinster, Beitriige zur Petrefactenkunde, 
Heft iii. 1840, p. 99, Taf. xix. f. 3.) 
A small, abraded fragment, partly buried in the matrix, may bo 
compared with Miinster’s species. 
It possesses the faint annulations and fine and regular raised lines 
characteristic of that form. 
Horizon. Upper Devonian ’. 
Locality. Lower Dunscombe, near Chudleigh, Devonshire.

Char. ‘‘ General figure rather rapidly tapering ; surface with 
prominent transverse rings, crossed by numerous fine threads, which 
alternate with still finer lines ; annulations sharp, oblique, distant 
•33 or ’5 diameter ; section (?) ; septa rather more approximate than 
the annulations ; siphuncle (?). 
^ These beds are placed by Mr. H. B. Woodward (Geol. of England and 
Wales, 2nd edition, p. 134) in the Middle Devonian, but Dr. Ferdinand 
Roemer correlates them with the'“ Red nodular limestone” (Goniatiten-Kalk) 
of Oberscheld, &c., which- is of Upper Devonian age. 
The annexed table exhibits very clearly the relationship between the Devonian 
strata of England and that of the Rhineland and Westphalia.
