MARINE FAUNA OF ST. ANDREWS. 
* 92 
the young of this group can be observed opens up an excellent 
field for future investigators. 
I have to thank the Rev. A. M. Norman for his kind 
assistance in revising the following list, and determining 
several Holothuroidea. 
Order II. Ophiuroidea. 
Fam. 2. Ophiuridae. 
Genus 4. Ophiothrix, Muller & Troschel. 
Ophiot.hr ix frag ills 1 O. F. Muller ; 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 jiliformis , 0. F. Muller; Norman, op. cit. p. 107. 
Occasionally in the stomachs of haddocks. Rare. 
Amphiura Chictjii , 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 under stones in rock-pools and near low water, 
especially towards the Rock and Spindle. 
Genus 7. Ophiocoma, Agassiz. 
Ophiocoma nigra , 0. 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.
