WENLOCK GROUP. 

Names and References; Observations, &c. 

Apiocystites pentremitoides, Forbes (Mem, 
Geol. Surv. Vol. m1. Pt. 2, pl. 15, figs. 1—9), 
Siluria, 2nd ed, Woodcut 54, fig. 4, 
Prunocystites, Forbes (Mem. Geol. Surv. Vol. 
11. Pt. 2, p. 503, pl. 16). 
Prunocystites Fletcheri, Forbes (ib. pl. 16, figs. 
1—4, Siluria, 2nd ed. Foss, 54, fig. 3). 
Pseudocrinites, Pearce. The first noticed of 
this group in Britain; but of course sup- 
posed to be a spurious kind of crinoid, with 
less than five arms. The three pectinated 
rhombs are thick-edged. 
Pseudocrinites quadrifasciatus, Pearce (Mem. 
Geol. Surv. ib. pl. 13, fig. 1), The com- 
mon species in Dudley limestone; rarely 
found elsewhere (Siluria, 2nd ed. Foss. 54, 
fig. 2). 
Pseudocrinites bifasciatus, Pearce. (Forbes, 
ib. p. 496, pl. 11). Only two arms, arranged 
as in P. magnificus. 
Pseudocrinites magnificus, Forbes (ib. pl. 12, 
fig. 1, Siluria, 2nd ed. Foss. 54, fig. 1). A 
very large species, the largest body of any 
(in Britain) with rhombs. 
Pseudocrinites oblongus, Forbes (ib, pl. 14, 
figs, 1—14, p. 499). 
Echino-encrinites, Volborth. A transverse long 
slit marks the place of the mouth; some 
doubt if this be quite the same genus as 
the Russian Upper Cambrian fossil de- 
scribed by Volborth: still more if ZH. bac- 
catus belong to the same genus,
