le Gauss II et V Antarctic ** n’ont pu traverser ce Cercle), n’en 
a obtenu de pareilles profondeurs ; de toutes ces Expeditions, c’est 
encore la Belgica qui suit la Scotia de plus pres, avec son Nemato- 
nurus Lecointei, peche a 2800 metres (1531 fathoms) de profondeur, 
dans la Mer de Bellingshausen. 
Au surplus, les deux Poissons en question , — Neobythites Brucei 
et Nematonurus Lecointei, — proviennent bien du fond meme 
de l’Ocean, puisque ce sont des Organismes Abyssaux adaptes 
a la Vie Benthique, comme en temoigne leur Queue Gephyro- 
cerque,ff acquise independamment, par un Phenomene de Con- 
vergence ( Neobythites est un Brotulidse , done un Acanthojpterygien ; 
Nematonurus est un Macruridre, done un Anacanthinien).

“ . . . It is disappointing to learn that we cannot expect any additions to 
the deep-sea fauna of the Southern Ocean. The wealth of new material 
collected by the Challenger in its one deep haul in the Antarctic, led to hope 
that valuable results would be achieved by the powerful deep-sea equipment 
of the Discovery ; but apparently it was very little used, owing to the short 
time spent at sea, and possibly on account of the limited coal supply. One 
dredging is referred to at the depth of 610 fathoms, another at 100 fathoms, 
and a third, also in shallow water, off the great ice-barrier. ” — J. W. Gregory,
