92 makine fauna of st. Andrews. 



the young of this group can be observed opens up an excellent 

 field for future investigators. 



I have to thank the Kev. A. M. Norman for his kind 

 assistance in revising the following list, and determining 

 several Holothuroidea. 



Order II. Ophiuroidea. 



Fam. 2. OpMuridae. 

 Genus 4. Ophiothrix, Muller & Troschel. 



Ophtothrix fragilis, O. F. Miiller ; Rev. A. M. Norman, 

 Ann. & Mag. Nat. Hist. February 1865, p. 107. 



Abundant under stones in rock-pools and near low- water 

 mark, and dredged in the water beyond to a considerable depth. 

 Many of the stones in the pools are covered with the ova of 

 this species about the middle of November ; and some of the 

 starfishes have them attached to the disk. 



Genus 5. Amphiura, Forbes. 

 Amphiura filiformis, 0. F. Muller ; Norman, op. cit. p. 107. 

 Occasionally in the stomachs of haddocks. Eare. 



Amphiura Cktajti, Forbes ; Norman, op. cit. p. 107. 

 Vast numbers are thrown ashore on the West Sands after 

 storms. It is also common in the stomachs of the cod and 

 haddock. 



Amphiura elegans, Leach ; Norman, op. cit. p. 109. 

 Frequent imder stones in rock -pools and near low water, 

 especially towards the Rock and Spindle. 



Genus 7. Ophiocoma, Agassiz. 



Ophiocoma nigra, O. F. Muller ; Norman, op. cit. p. 111. 



Not uncommon from deep water (by dredging and the deep- 

 sea lines of the fishermen). It does not occur in profusion, as 

 in many parts of the Zetlandic and southern portions of our 

 seas.
