along with Orth. Chinense. Mr. Davidson referred them to “ eight 
Devonian s^jecies, seven of which are common to several European 
localities,” such as Eerques and Nehou (France), Belgium, and the 
Eifel. Dr. Grieve’s paper throws no additional light upon the question 
of the age of the beds holding Orthoceras Chinense. 
This species is mentioned in the volume upon the Palaeontology of 
China ^ which accompanies E. von Eichthofen’s ‘ China,’ but it was 
not represented among the fossils examined by the palaeontologists 
engaged upon that work.

Locality. The specimens whose dimensions are given above came 
“ from some place 200 miles distant from Shanghai,” and were pre- 
sented to this Museum by Daniel Hanbury, Esq. Another specimen 
(No. 88,986) is stated to be “ from the interior of the Province of 
Quang-Tung, China.” The latter was presented by the Hon. K. 
Marsham, in 1877.

Sp.Char. SheE straight. Section nearly circular. Rate of increase 
about 1 in 10. Septa very numerous, slightly waved. Siphuncle 
nearly central. Surface very minutely striated transversely. 
RemarTcs. This species resembles Fleming’s 0. pyramiclale in 
general habit, but it tapers more slowly, and has much more 
numerous septa. M‘Coy observes (British Pal. Foss. loc. cit.) that 
the original Devonshire specimens figured by Sowerby in the Geo- 
logical Transactions (2nd series, vol. v. pi. Iii, ff, 6, 7) under the 
name 0. cylindraceum are indeterminable fragments, and cannot be 
referred with certainty to this or any other species. 
Horizon. Carboniferous Limestone^. 
Locality. Near Matlock (?), Derbyshire.
