refer N. speciosa, Voltz, as identified by D’Orbigny (Terr. 
eu a ii. p. 123, pl. 269, figs. 1 and 2), or N. cecilia, D’Orbigny 
(vol. ii. p. 181, pl. 272, figs. 1-4). The general outline and angular 
measurements of these species—especially of the latter, which only 
differs in some details of ornament—are far nearer to those of our 
shell than are the dimensions of Roemer’s species, with which it has 
itherto been identified. 
ne ae to bear in mind that the base of the Coralline Oolite of 
Pickering, where N. pseudovisurgis most frequently occurs, belongs 
to beds which, in France, would be classed as Oxfordian. It also 
oceurs towards the top of the Coralline Oolite at Ayton and Seamer, 
where there is perhaps another, though somewhat similar species. 
Less frequent in the Howardian Hills. Often associated with 
Chemnitzia Heddingtonensis. The cast (Pl. XVII. Fig. 5) may 
represent an internal mould of this species.

Bibliography, etc.—The Nerinea fasciata of Voltz (Neues Jahrb. 
1836, p. 542, pl. vi. fig. 21) is supposed to be different from Roemer’s 
N. fasciata, as quoted in the Nordd. Ool. Gebirges. Brauns (Obere 
Jura, p. 208) reunites them. The Yorkshire shell in question tallies 
with Goldfuss’s figure, but the form is abundant, and doubtless 
slight variations have been productive of many names. D’Orbigny’s 
representation of N. fasciata, Voltz (Terr. Jurass. vol. ii. p. 121, pl. 
268, figs. 8 and 4), is not at all like the Yorkshire species now 
under consideration. The figure in D’Orbigny which most re- 
sembles elongate specimens of the Yorkshire species is N. Allica 
(op. cit. p. 98, pl. 255) from the Oolitic Limestone of the Upper 
Oxfordian, Trouville. This is probably Bean’s “allongiuscula” in 
art. 
i Description.—Fragment from the Corallian of Yorkshire, with 
ornaments well preserved. Matrix oolitic. (Leckenby Collection.) 
Spiral angle about 6°. Shell narrow, cylindrical. The whorls fit 
closely to each other, and are but little depressed in the centre. 
The bounding rim of each whorl is slightly raised so as to produce 
a salient belt, devoid of tuberculation. Within this space are six 
transverse coste. The second, fourth, and sixth of these rows are 
the strongest, and most tuberculated: the first and fifth are little 
more than faint lines. 
Relations and DistributionThe species referred as above, or 
something very like it, is by far the most widely spread and abundant 
of this genus in the Corallian rocks of Yorkshire, ranging as it does 
from the Oolite of the Lower Limestones (see generalized scheme, 
pp. 246, 247) through the whole of the Coralline Oolite into the 
Coral Rag. Thus it is both Oxfordian and Corallian. The follow- 
ing remarks of D’Orbigny, with reference to his Nerinea Allica, may 
be quoted.
