Fawna of the Lower Devonian of Torquay. 321 
indicate its reference to Hall’s genus, Newberria,! of which the type 
is Rensselaria ? gohannis Hall.2 Our shell may be compared with 
N. deshayesi (Caillaud) from the Huropean Lower Devonian, and 
it shows well the elongate subovate adductor scars divided by a thin 
ridge (as in Caillaud’s figure), and the very narrow submarginal 
dental sockets which Hall & Clarke illustrate (op. cit. pl. Ixxviii, 
fig. 11)in N. johannis. Giirich * adopts the name Newberria for the 
two European species, Terebratula caiqua D’Arch & Vern. and 
T. amygdala Goldf., but he does not mention T. deshayesi Caill. 
or Meganteris inornata D’ Orb., both of which Hall & Clarke (op. cit. 
pp. 264, 281) consider are referable to Newberria. Dielasma rhenana 
Drevermann 4 may also belong to this genus.

Davidson’s figures of the British examples do not show the decrease 
in the strength and distinctness of the lateral ribs, which is a 
characteristic feature, and is well seen in specimens in the Jermyn 
Street Museum. The number of the ribs varies, and according to 
Drevermann (op. cit.) is of little importance, and there is a con- 
siderable range of variation in the closely allied or scarcely separable 
American species (Tr. carinatus Conr.), from the Hamilton 
Formation.®> It is probable that Etheridge’s Rhynch. laticosta 
Dav., from Smugglers’ Cove, should be referred to Tr. rhenanus, 
for it seems to possess the typical characters. Upfield Green ° has 
recorded it from the ‘“‘ Gedinnian”’ of Cornwall, and Davidson 
had previously given Looe as a locality for its occurrence. It 
seems to be fairly common in the Meadfoot Beds, but crushed 
specimens of Ch. plebeia have often been mistaken for it, and are 
difficult to distinguish.
