Fauna of the Lower Devonian of Torquay. 315 
Devonian age, is closely allied to Str. Murchisoni and Str. virgata 
Drev.,! but it varies somewhat in the development and number of 
its ribs, and consequently Kegel? has established the variety 
rudis for those forms possessing few and coarser ribs which occur 
in the Taunus quartzite. Two fragmentary valves from the 
Smugglers’ Cove red beds have been recognized, one of which shows 
the cardinal region of the internal cast of a brachial valve, and 
both agree with Kegel’s variety in the character of the ribbing 
rather than with the type. 
Horizon.—Red Beds (Staddon Grits). 
Locality.—(1) Smugglers’ Cove (S. 100); small cove immediately 
south of Smugglers’ Cove (Shannon Coll.). 
Stropheodonta gigas (McCoy). 
It is unfortunate that McCoy’s? type of this species, which is from 
Looe, is in a poor state of preservation, and only shows the external 
ornamentation. Davidson ‘ figured the interior of a pedicle-valve 
and Drevermann® the interior of a brachial valve, giving at the 
same time a full description of the specific characters. At Meadfoot 
it occurs in a tough siliceous bluish cleaved slate, with numbers of 
Chonetes plebeia, Ch. sarcinulata, Spirifer sp., and Plewrodictyum 
problematicum. One specimen (22%) in the Jermyn Street Museum, 
simply labelled ‘‘ Torquay ”’, occurs in the rotten calcareous, sandy 
rock of Kilmorie, and shows the internal cast of a pedicle valve, 
while another (1245) in the Ussher Collection shows the denticulations 
along the hinge-line of the brachial valve. It is possible that 
Strophomena proteniolata Béclard,® is identical with this species. 
Horizon.—Meadfoot Beds. 
Localities —Meadfoot (8. 49, 50); East of South Bank (Ussher 
Coll., 1245 M.P.G.) ; “‘ Torquay ”’ (? Kilmorie) 22 M.P.G. 
Leptena rhomboidalis (Wilckens).

figs. 43, 44. 
This well-known Silurian species, which does not seem to be 
specifically separable from that occurring in the Lower Devonian 
of Europe and America, is represented in the Sedgwick Museum 
by one good example from a dark grey lustrous slate, labelled “ The 
Knoll, South of Meadfort Sands”. Williams and Breger (op. cit. 
p- 32, pl. viii, figs. 8-12) describe specimens of it from the Chapman 
Sandstone of Maine, and give references to the American literature,
