80 REPORT— 1839. 



found five species of the genus Eolida. Of these, four were unde- 

 scribed, the other being Eolida papillosa of authors, which abounded 

 in Shetland, under stones at half tide, whither it appeared to resort for 

 the purpose of spawning. The four new species are named by the 

 authors E. Zetlandica, E. coronata, E. foliata, E. minima ; the two 

 last were obtained by dredging in seven fathoms' water. They found 

 no Eolidae in Orkney. 



Of the genus Euplocamus they found one species, allied to the 

 Euplocamus pulcher {Triopa clavigera of Johnston), but differing 

 from that species, in having its branchiae, both lateral and dorsal, 

 tipped with yellow. Its back is white, spotted with yellow. Of the 

 genus Doris they found two species, one the Doris pilosa of MUUer, 

 and the other Doris hervicensis of Johnston. 



They found one new testaceous mollusk, a species of Velutina, 

 which the authors have named Velutina elongata. Ascidiae abound in 

 the north ; the more common species is the Ascidia intestinalis. Along 

 with it they found three species, which, there is reason to believe, are 

 undescribed. The authors propose to name them Ascidia echinata, 

 Ascidia rugosa, Ascidia rubens, the two latter are from Orkney. Of 

 Annelides the authors found great numbers ; such as they collected 

 they intend submitting to Dr. Johnston, as the highest British authority 

 on that class. They observed Planariee in great numbers : among 

 others was the beautiful Planaria atomata of Miiller, not before re- 

 corded as British. Among the Radiate animals they were especially 

 successful. The genus Holothuria is conspicuous in Shetland ; among 

 them is an enormous species, which the authors name Holothuria 

 grandis. This splendid animal is fully two feet long, when extended ; 

 it is of a deep purple colour ; it has ten triangular frondose tentacula, 

 purple, spotted with white ; its body, between the rows of suckers, is 

 almost smooth. The other new species of this genus observed were — 

 Holothuria fucicola, Shetland, Holothuria brevis, Holothuria fusif or mis, 

 Holothuria lactea, Holothuria pellucida of Miiller. Along with Holo- 

 thurise the authors dredged the Priapulus caudatus, and Sipunculus 

 strombi. They found no Holothurise or Priapuli in Orkney. 



Of the sea-urchins they found only the Echinus esculentus, and a 

 form which appeared to be the Echinus neglectus of Lamarck. The 

 star-fishes observed were Asterias aranciaca, and an allied form, pro- 

 bably the Asterias bispinosa of Otto, Stellonice rubens and violacea, 

 Luidia fragilissima, Solaster papposa, Ophiura albida and texturata, 

 Ophiocoma bellis, granulata, rosula, neglecta, and a new species. The 

 Medusae doubtless abound in these islands in August, their proper 

 season ; but when the authors of the paper were there, they observed 

 only Cyancea capillata, Medusa aurita, a new Dianaea, a new Oceanea, 

 a new Ciliograde, of the genus Alcynoe of Rang, and a minute ani- 

 mal, the type of a new genus among the Acalephae. Sponges of the 

 genera Grantia and Holochondria abound in Shetland. From deep 

 water the authors obtained several specimens of Tethya cranium, and 

 kept them alive in salt water, but could observe none of the contrac- 

 tions stated to have been seen in that species by some of the French 

 naturalists.
