190 Mr. F. A. Bather on British Fossil Crinotds : 
This species is founded on two specimens in the Wood- 
wardian Museum, Cambridge :— 
a/435. Upper Wenlock Limestone, Dudley. Fletcher Coll. 
(Pl. XI. figs. 1 and 2). 
For permission to figure and describe these specimens I am 
indebted to Prof. T. MeKenny Hughes, F.R.S. 
SPECIFIC DIAGNOSIS. 
Cup elegant, widening above. RR _ projecting very 
slightly ; facet about 3 their width. Arms about seven times 
length of cup, two-branched, with small armlets. (Anal 
structures unknown.) Stem comparatively stout and 
markedly quinquelobate, with alternate-sized ossicles. 
DESCRIPTION OF THE SPECIMENS. 
The two specimens are figured on Pl. XJ., No. 1 being the 
large specimen and No. 2 the small. They are both seen 
from the anterior, and show no trace of anals or of the ventral 
sac. 
Dorsal cup.—In both the plates are a little disturbed and 
the cup is flattened, so that measurements of its height and 
width are liable to correction. They are as follows :— 
Height. Width below. Width above.
