70 Review of the New York Geological Reports. 
of Strombodes,* Hall supposes this fossil to belong to that genus: 
If the presence of transverse plates, like the septa of Nautilus, 
traversing the axis of turbinated corals, is to be regarded as char- 
acteristic of a true Cyathophyllum, then the coral in question 
may be entitled to rank as a separate genus, but looking to the 
original description by Schweigger of Strombodes,t we are en- 
tirely at a loss to conceive how corals analogous in structure to 
figs. 3; 4, 5, 6, can be placed in that genus. Here is the transla- 
tion of Schweigger’s description of Strombodes. 
A calcareous coral stem composed of lamellar, conical cells ly- . 
ing parallel and vertical beside one another, and connected by 
their expanded margins growing together in the same horizontal 
an second and third grows up out of the previous one to 
an equal height with the adjacent ones, their broad margins being 
in like manner connected together. Thus the coral appears to be 
made up of a series of connected, horizontal, vaulted partitions 
resting on pillars which permeate the mass. 
From the above it is evident that Strombodes is essentially 
composed of horizontally disposed, vaulted partitions, whilst 
these corals consist of vertical lamella. Now, we would inquire, 
why should the partial contortion of the vertical lamella around 
the axis of the coral constitute it a Strombodes? "Turning to the 
figure of S. pentagonus, pl. 21, fig. 2, a, b, of Goldfuss, and ex- 
amining the numerous specimens of fossil corals of a similar 
structure in our possession, we find the vaulted lamine of which 
they are made up, to dip into a pillar-like axis, but without the 
slightest convolution, and even if they did, still no analogy could 
exist between them and the vertically disposed, partially con- 
torted lamelliferous corals like the figures referred to. 
We find it difficult even to admit.a generic analogy between . 
Strombodes of Schweigger, and Lonsdale’s S. plicatum, fig. 4, a, 
b,c, pl. 16, bis, (C. plicatum of Gold. fig. 5, pl. 18,) composed of 
crimped, funnel-shaped Jaminz: ; the more especially if these, as 
_we are led to infer, are spirally contorted around the axis of the 
oral. . | 
The better to illustrate the above remarks, we subjoin two fig- 
ures of Strombodes, drawn from western Specimens in our collec-— 
tion. Fig. 1 seems to be of the same species as Goldfuss’s S. 
pentagonus, though the diameter across the margins of the arch- 
ed partitions is much greater, and their outline more irregularly, 
pentagonal. In fig. 2, which is doubtless a distinct species, the
