OPHIURIDA. 
Ophioglypha lacertosa (Linck). 
O. allida (Forbes). 
O. affinis (Liitken). 
Firth of Forth (£. #.); Firth of Forth 
(MB.). 
This species is the Ophiwra textwrata of 
Forbes. It is common near the mouth of 
the Firth, and becomes scarcer higher up. 
We have dredged it on several occasions 
at depths of 4 to 7 fathoms. 
Firth of Forth (4. F.); Firth of Forth 
(MB.). 
The Ophiura albida of Forbes. It is a 
very abundant species in the Firth, and 
we always obtained it in great numbers on 
the oyster banks near Inchkeith, and 
further down the estuary. It prefers 
sandy bottoms. 
Bass Rock, 24 fathoms (I. & £.).* 
Ophiocoma nigra (O. F. Mill). 
Firth of Forth (M‘B.); Firth of Forth 
(F. M. B.). On the deep-sea lines. 
Ophiocoma granulata of Forbes. This 
species is not common in the Firth. We 
have obtained it at Newhaven, the speci- 
mens having probably been brought in on 
the fishermen’s lines from the vicinity of 
the May Island. On some parts of the 
west of Scotland this is the most abundant 
species in a few fathoms of water. 
Ophiopholis bellis (Johns.). 
Firth of Forth (Howd.); Prestonpans (Ed.
