beyond this depth it is not so frequently met with. It is by far 

 the commonest of the sand-stars.

Durham coast, six to twenty-five fathoms, common. Berwick 

 Bay and Fame Islands, twelve to forty fathoms, frequent, G. H. 



This recent addition to our fauna was made known in the 

 Tyneside Transactions for 1863, under the name of Ophiura 

 Normani. It was however subsequently discovered that Liit- 

 ken, the Danish naturalist, had taken it two years previously, 

 and named it 0. affinis. It is a pretty and interesting species, 

 which had escaped notice on our coast, although common. Re- 

 markably fine specimens were obtained in Berwick Bay during 

 the several dredging expeditions under the auspices of the Brit- 

 ish Association. The Rev. A. M. Norman has specimens from 

 the Clyde, and also from Shetland.

Cullercoats, very rare, J. A. Berwick Bay, twenty-five to 

 forty fathoms, rare. Durham coast, very rare, G. H. 



This is undoubtedly the rarest of our sand-stars. It was first 

 recorded as British in the dredging reports for 1863, although, 

 as then stated, it was known to Mr. Alder and myself from two 

 specimens which we had previously obtained from the fishing 

 lines — he at Cullercoats — myself at Seaham. Mr. Norman has 

 since informed me he had a single specimen from the dredging 

 expedition of 1862. It was not taken during the last trip, 

 although operations were mostly confined to the spot near to 

 which nine or ten specimens were obtained in 1863.
