OPHIUROIDEA. 



Ophiueidjl. 



Ophioglypha lacertosa (Linck). 



Firth of Forth {E. F.); Fbth of Forth 



{3f'B.). 



This species is the Ophiwa tecdurata 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. 



0. cdhida (Forbes). 



Firth of Forth {E. F.) ; Firth of Forth 

 (M'B.). 



The Ophiura cdhida 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. 



0. affinis (Ltitken). 



Bass Rock, 24 fathoms {M. & B.)* 



Ophiocoma nigra (0, F. MiilL). 



Firth of Forth {M'B); Firth of Forth 

 {F. M. B). On the deep-sea lines. 

 Ophiocoma gramdata 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 hellis (Johns.). 



Firth of Forth {Howd) ; Prestonpans {Ed.
