Fauna of the Lower Devonian of Torquay. 317 
Jermyn Street Museum. Whidborne+ has doubtfully referred 
some specimens from the Morte Slates of Treborough to this species. 
Fuchs? has separated off some of the shells figured by Kayser 
under this name as a new species, Ch. oblonga, and also considers 
Ch. subquadrata Roem. to be merely a variety of Ch. sarcinulata, 
but it is difficult to make out the alleged specific differences in the 
Torquay specimens. It is much to be regretted that there exists such 
difference of opinion and uncertainty with regard to its specific 
distinction, for Gurich® states that it is the most widely distributed 
species of the Lower Devonian. The American species, known as 
Ch. novascoticus Hall,* may perhaps be identical. 
Horizon.—Meadfoot Beds. 
Localities —Meadfoot (8. 48, 49, 50); below Kilmorie (22 M.P.G.). 
Camarotechia daleidensis (Roemer).

There is a considerable range of variation in this species, and its 
separation from Rh. livonica von Buch, has not always been 
recognized, but it lacks the parietal ribs on the sinus and on the 
saddle, which are present in that species. Kayser ®> remarks that 
it much resembles kh. nympha Barr., but has no lateral excavations 
on the shoulders of the valves. Drevermann® points out that 
Rh. daleidensis is referable to Hall & Clarke’s subgenus Camarotechia. 
Rh. hexatoma Schnur, which Fuchs’ describes from the Remscheider 
Beds, seems hardly separable as a distinct species. The specimens 
in the Sedgwick Museum were obtained from the Red Beds of the 
New Cut, but Kayser ° recorded it from the cliffs and beach below 
Kilmorie.
