REPORT ON THE ASTEROIDEA. 601 
“ Porcupine” Expedition : 
Station 51, 1869. In the Faerde Channel. Lat. 60° 6’ 0” N., long. 8° 14’ 0” W. 
Depth 440 fathoms. Bottom temperature 5°°5 C. ; surface temperature 10°:9 C. 
Other examples of Odinia pandina were also obtained during the “ Porcupine” dredg- 
ings, but unfortunately they are without record of station or locality. 
Remarks —This handsome form was confounded by Sir Wyville Thomson with 
Brisinga coronata, the figure which he gives under that name in The Depths of the 
Sea (fig. 5, p. 67) being without doubt the Asterid above described. In the specimen 
preserved, all the ras, excepting several of the small recurved ones, are now separated 
from the disk; but notwithstanding this, I feel little or no hesitation in believing that the 
example before me is the one from which the drawing for the woodcut was made. The 
general form, the character of the spinulation of the ovarial regions, the irregularly dis- 
posed sacculi with crowded pedicellariz upon the rays, the vertical lateral series of spine- 
lets, and the large single actinal spinelets on the adambulacral plates, are all faithfully 
represented ; if to these characters be added the presence of papule, the shortness of 
the adambulacral plates, the strongly spinulate disk (which is not sufficiently shown in 
the woodcut), and the form and armature of the mouth-plates, we have a congeries of 
characters readily ‘distinguishing Odinia pandina from Brisinga coronata. 
Genus Brisinga, Asbjornsen. 
Brisinga, Asbjornsen, Fauna Litt. Norvegie, 1856, Andet Hefte, p. 95. 
Since the discovery of this remarkable Asterid thirty-five years ago by the Norwegian 
poet, Asbjornsen, in the picturesque Hardanger Fjord, a considerable number of allied forms 
have rewarded the dredging operations in deep water which have since then been under- 
taken, and the type that was once thought so rare and limited in occurrence is now 
found to possess a world-wide distribution. Owing to the great similarity in general facies 
of all the members of the group, a certain laxity of conception as to the generic scope of 
Brisinga sprang up, and a number of species were provisionally set down as Brisinga 
which present characters that entitle them to stand as independent genera. In my pre- 
liminary note on the deep-water forms of the starfishes collected by the Challenger, I 
myself! referred to a number of these under the name of Brisinga. In 1885, Perrier’ 
proposed a limitation of the genus, with which I entirely concur; indeed, prior to the 
publication of his memoir on the Asteroidea of the “ Travailleur” and “ Talisman” Expedi- 
tions, I had drawn up the synopses of species here given, in which the forms now placed 
under Odinia and Freyella were recognised as independent genera; for these I have great 
pleasure in adopting the admirably chosen names assigned to them by my learned col- 
league, in preference to the MS. names I had proposed to give them.
