square miles of sea-bottom, the great mass of the specimens procured 

 are dead; but on one occasion, about 10 miles east of Balta, in 70 

 fathoms, the dredge came up containing literally thousands of living 

 Caryophyllese. 



Paracyathus thulensis, Gosse. The type specimen was " dredged by Dr. 

 Howden off Ord Head, in Bressay Sound, Shetland, in 30-40 fathoms, 

 on a bottom of small stones, to one of which it was attached " (Gosse).

 100 fathoms, sandy ground, 1861 ; and one specimen 70-100 fathoms, 

 Unst Haaf, 1864. 



Lophohelia prolifera (Linn.). Besides the specimen in the Newcastle Mu- 

 seum (Johnst. Brit. Zooph. p. 251) a second fine Shetland example is 

 now in the British Museum, which was procured some years ago by Dr. 

 Edmonston from the Unst fishermen, and by him given to Mr. Jeffreys, 

 who presented it to the British Museum.

All existing British works are now so far in arrear that I could not with 

 any degree of satisfaction follow the arrangement given in them. At my 

 request, therefore, Mr. Hincks has kindly supplied me with a MS. copy of

 droida, and this I have adopted in the following Report.
