This small species occurs in considerable abundance in the Red 
Beds of the New Cut and in the slaty beds of Meadfoot, but is often 
distorted, and always crushed. Whidborne has also recorded Ch. 
plebeia from the Morte Slates, but Davidson made no mention of 
the occurrence of this species in the British Isles. It is a conspicuous 
form in the Lower Coblenzian of the Continent, but ranges up into 
the Upper Coblenzian, and perhaps higher. 
Horizons.—(1) Red Beds (Staddon Grits) ; (2) Meadfoot Beds. 
Localities —(1) New Cut and Lincombe Drive (8, 14, 15, 16, 28) 
(T. 2£); (2) Meadfoot (S. 48, 49, 50, 64) (M.P.G. 23) (M.P.G. 1208, 
1210, 1211 Ussher Coll.) ; (4) New Drive from Hope’s Farm (M.P.G, 
1157, Ussher Coll.) ; (5) South of Hope Farm, edge of Bramblebrake 
(M.P.G. 1181, Ussher Coll.). 
Chonetes sarcinulata Schlotheim. 
The characters of this species and its separation from other allied 
forms have always been in doubt owing to the difficulty of deciding 
what fossil Schlotheim intended to designate by this name.? 
Davidson ? put it (together with Ch. sordida (Phill.*) as a probable 
synonym of Ch. hardrensis Phill., which is typically a Carboniferous 
species. But if we adopt Kayser’s 4 views on the matter, we appear 
to have it represented in the Torquay district at Meadfoot and 
below Kilmorie, though, unfortunately, none of the specimens 
which I have examined are well preserved. Kayser ° himself recorded 
it from the Meadfoot Beds below Kilmorie, and there is a specimen 
from this locality ($2) thus labelled by De Koninck in 1873 in the
