320 REPORT—1868. 
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 
Caryophyllez. 
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). 
Ulocyathus arcticus, Sars. Forty miles east of Whalsey Lighthouse, in 80— 
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, 
Order ALCYONARIA. 
Vennatula phosphorea, Linn. In great profusion, in 30-60 fathoms, in St. 
Magnus Bay, on a very muddy bottom; an occasional specimen now 
and then taken elsewhere. 
Virgularia mirabilis (Linn.). On Haddock- grounds, frequent. 
Gorgonia pinnata, Linn. A specimen in British Museum. ‘“ Zetland, E. 
Forbes, Esq. Presented by G. Johnston, M.D.” (Cat. Brit. Radiated 
Anim. p. 56). 
Primnoa lepadifera (Linn.). “Coasts of Shetland, Jameson” (Johnston, 
Brit. Zooph. p. 171). 
Alcyonium digitatum, Linn. 
glomeratum, Hassall. An orange Alcyonium from a cave at Hillswick 
seems to be referable to this. ‘‘ Rocks, Out Skerries and Balta Sound ” 
(Peach in litt.). 
Rhizoxenia catenata (Forbes). Dourie Voe, and 1 mile N.E. of Whalsey 
Lighthouse; also off Balta. This is the Sarcodictyon catenata of Johnston. 
Order CTENOPHORA. 
Idyia cucumis (Fabr.). Frequent, towing-net. 
Clas HY DROZOA. 
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 
the classification which he will propose in his forthcoming work on the Hy- 
droida, and this I have adopted in the following Report. 
Order LUCERNARIADA. 
Aurelia aurita (Miiller). 
Cyanea capillata (Lamk.). 
Lucernaria quadricornis (Miller). On Fuci at low water, Bressay Sound, and 
Unst. 
auricula,O. Fabr. “ Tide-marks, on weeds, Out Skerries, found by Miss 
Jeffreys ” (Peach in litt.). 
Carduella cyathiformis (Sars). Professor Allman tells me that he found this 
species in 1862.
