886 Prof. T. R. Jones and Dr. Woodward—Devonian Fossils. 
but it differs from E. punctata, Hall (fig. 2, after Beecher, about 
two-thirds of the natural size), in being rounder behind, and 
truncate in front,—in the arrangement of the cephalic prominences, 
—and particularly in having two parallel ridges, instead of one 
- sigmoidal ridge. So also it differs from E. sublevis, Whitfield, H. 
condylepis, Clarke, E. multinodosa, Whitfield, and E. Whitfieldi, 
Clarke. H. pustulosa, Clarke, has only one tuberculate ridge. 
E. socialis, Beecher, has the two parallel ridges, and the valve is 
slightly pustulose here and there; but it is smaller and more ovate 
than the specimen under notice ; and the cephalic swellings, though 
analogous, are not identical. 
As it is evidently a new species we propose to name this unique 
fossil from Devonshire Ecuinocaris WHIDBORNEI, after the Rev. 
G. F. Whidborne, F.G.S., who drew our attention to the specimen, 
and first recognized its true affinities. 
Mr. J. E. Marr, Sec.G.S., informs us that this rare fossil was 
found by Mr. Dufton in the leaden-blue shales of the Lingula- 
squamiformis beds in a quarry near Sloly, close to the three-milestone 
on the Barnstaple and Ilfracombe road. The shales (he adds), which 
are here interstratified with very micaceous frilled sandstones, 
belong to the Cucullza-zone of the Marwood Beds. The specimen 
is preserved in the Woodwardian Museum, Cambridge, and has been 
kindly lent to us by Prof. T. McKenny Hughes for examination and 
description.

Figs. 8, 4, 5 show internal casts of some large Beyrichie from the 
Devonian strata near Torquay, in Devonshire, in different states of 
preservation. Nine or ten other such specimens were sent to us for 
examination by Thos. Roberts, Esq., F.G.S. They are all preserved 
in the Woodwardian Museum, Cambridge, and are imbedded in a 
finely micaceous, purplish-grey, schistose mudstone, weathering red, 
from the New Cut, above Meadfoot, Torquay. The fossils occur, 
sometimes on a cleavage-plane, more frequently on the bed-planes, 
compressed and distorted by pressure; and therefore rarely (as 
Fig. 3) escape some such modification. The test of the valves has 
gone, and the casts and moulds are both coated with ruddle, which 
in some cases seems to represent the test. 
Figs. 8a—e. This is the internal cast of a simple three-lobed 
Beyrichia (4 mm. long, by 2 high), having, in the curved ventral 
junction of the two hinder lobes, some analogy to both B. Buchiana, 
Jones, and B. Kledeni, var. antiquata, Jones,—which are of Upper 
Silurian age. In the shape and size of the valve, however, and the 
proportions of the lobes, it differs from both. Another good cast 
(6 xX 2:5 mm.) differs slightly from Fig. 8, appearing sharper in 
front and blunter behind, if looked at on edge,—that is, the anterior 
lobe is rather further from the front margin, and the posterior lobe 
nearer to the hinder margin. 
The impression from out of which some of these and other casts 
have come indicate no other characters of the surface except what
