in a general sort of way with Pl. Anglica, Sow. I quote the following :—* Owing 
to the imperfect condition of the shell, an absolutely correct identification of 
the Dogger fossil with this or that member of the Anglica-group is almost 
impossible. It comes very near to Pl. araneosa, Desl.’”’ (‘ Geol. Mag.,’ dec. 3, 
vol. u, p. 154, pl. iv, fig. 5). This is about as near as we can get pending the 
discovery of better specimens. 
N.B.—Whatever may have been the original or originals of Pl. Anglica, 
Sowerby, that species seems now to be restricted to certain wide-angled tabulate 
forms which occur in the Lower Lias.

Bibliography, §c.—Pl. Yeovilensis was described by Tawney at a time when 
good specimens were rare. The locality ‘‘ Yeovil” was given because so many of 
the Bradford Abbas fossils in those days were supplied to collections and museums 
by ‘‘ fossil-men” who resided at Yeovil, the nearest town to Bradford Abbas. 
The species is one of remarkable beauty, and interesting as the representative 
of the Granulate in the Lower Division of the Inferior Oolite. Pl. Alcibiades is 
possibly a more depressed and less ornamented form; this, too, in France most 
likely occurs on a low horizon, not being noted from the “ Oolithe ferrugineuse.”’

Spiral angle . - ; eelO be 
Shell conical-depressed, deeply umbilicate. Spire regular and sharp, with a 
slightly flattened apex. Whorls (seven) subangular and sloping; suture sub- 
canaliculate. The whorls exhibit fine reticulate ornaments, having the tendency 
to become granulate ; whilst in the two last whorls an elegant tuberculate corona 
is developed on the posterior ridge, the tubercles radiating away from the centre. 
The sinus-band is very salient, being situated at the anterior angle in the 
whorls of the spire; it has granulated spiral lines to the number of three. The 
body-whorl is relatively very large, and, in addition to the posterior corona and 
the prominence of the sinus-band, exhibits a thick tuberculated belt at the 
periphery ; these tuberculations are drawn out radially, and correspond to the 
tuberculations of the corona. The base is subconvex, being excavated by a deep
