Remarl's. In an interesting paper contributed to the Geological 
Magazine \ Dr. Ferdinand Eoemer recognized in the Fpper Devo- 
nian limestone of Lower Dunscombe, Devonshire, two species of 
Goniatites, viz. G. intiimescens. Deyr., and G. midtilohatus, Beyr. 
{G. Sagittarius, G. & F. Sandberger), remarking that “besides these 
Goniatites, a subcylindrical Orthoceras is especially abundant. It is 
perhaps identical with 0. acuarium, Mlinster, which the brothers 
Sandberger have obtained at Oberscheld ; but it is too imperfect to 
admit of identification with certainty.” 
The species here referred to has been lately supplied in abun- 
dance to the National Collection by the late Mr. John Edward Lee, 
of Torquay. 
I have, however, nothing to add to Dr. Koemer's observations as 
touching its identity.

of the body-chamber, with indications of longitudinal, close-set 
ridges marked upon the cast, is referred doubtfully to this species.
