ferent forms ; one Anomia, one Terchr alula attached 

 to a FusuSj two Lepas, and a Balanus. Six IIolo- 

 thuria, belonging to three different species, were 

 observed : a large Thalassema gave us a long-wish- 

 ed for opportunity of observing, that this species 

 belongs to the Holothuria, and not to the Annu- 

 lides. Eight species of star-fish are found here, 

 partly on the rocks, and partly at the bottom of the 

 sea : among them, four are furnished with five radii, 

 and the rest with six, ten, eleven, and eighteen : 

 the latter sort, which is the largest, lives at the 

 bottom of the sea, and the number of its radii varies 

 from eighteen to twenty-one. Only one Ophiura 

 was seen. Several kinds of very large Actinia in- 

 habit the rocks : all that we examined belonged to 

 the species which is externally provided with rows of 

 teats. A Velella also was caught in the open bay : 

 this is the first w^hich has been observed in so high 

 a latitude. 



Of Zoophutesy some presented themselves of the 

 genera AntipatheSy Milhpora, Cellaria, Flusfra two 

 species, Melobesia^ Retepora, AcamarduSy Lafcea, 

 Aglaopkenia, Dynamena fives pecies, Clytia four 

 species, and FoUiculina, two species. The Anti- 

 pathes consists of a simple stem resembling wood, 

 which grows to the length of ten feet : it grows at 

 a great depth in the open bay, and is often acci- 

 dentally drawn up in fishing. 



Although of all insects of this island the beetle 

 is the most numerous, yet during the whole spring
