110 DEVONIAN FAUNA. 
1885. SprriFER eiBBosus (Barrande), Maurer. Abhand]. Grossh. Hessisch. Geol. 
Landes., vol. i, pt. 2, p. 159, pi. 
vi, figs. 19—21. 
Localities.—There are from Lummaton seven specimens in my Collection, five 
in the Woodwardian Museum, and two in the Torquay Museum. From Wolborough 
there is a specimen in the ‘Torquay Museum. 
Remarks.—1 cannot agree with Davidson that Sowerby’s Sp. pulchella is a 
variety of Sp. nuda. His type specimens in the Museum of the Geological Society 
appear to me exactly to agree with the present shell, and, moreover, they show 
indistinct traces of the transverse ornament, which is like that of the present 
species, and unlike that of Sp. nuda. As, however, it seems clear that the Devo- 
nian species is identical with the Carboniferous shell described by Phillips in the 
‘Geology of Yorkshire,’ the name Sp. pulchella simply becomes a synonym of 
Sp. wmsculpta. 
The shell described by Maurer as Spirifer gibbosus, Barrande,' appears to me 
identical, the distinctions which he draws being probably due to accidents of 
fossilisation or individual variation. Our specimens, for instance, do show radiating 
lines crossing the transverse ridges. Barrande’s own shell has finer ridges and a 
flatter fold. 
The shell given by Barrois’ as Sp. Jaschei, F. A. Romer,* young, is very 
similar, and may perhaps belong to this species rather than to the German shell 
to which he refers it. 
8. Genus.—Crrtia, Dalman, 1828. 
1. Cyrrtia? Waipsornel, Davidson. 
1882. Cyrria ? WuHIpBorNeEr, Davidson. Brit. Foss. Brach., vol. v, pt. 1, p. 36, 
pl. ii, figs. 6, 7. 
Localities—From Lummaton there are eighteen specimens in my Collection, 
seven in the Woodwardian, one in the British Museum, and two in the Torquay 
Museum. One small example from Wolborough is in Mr. Vicary’s Collection. 
Remarks,—This is rather a variable species, being sometimes very transverse 
and sometimes having no lateral ribs on the dorsal valve. Occasionally the beak 
is slightly arched forward, so that the area becomes concave ; but generally it is, 
as described by Davidson, flat.
