with by the “ Challenger” in the Japanese Sea and South Atlantic 
at depths of 345 and 600 fathoms, seem to be quite common in the 
British district, having been obtained at Station 4 in 555 fathoms, 
and at Station 6 in 530 fathoms. 
8. Brosmius brosme , Mull. — A large example in 530 fathoms (11th 
August 1880) ; new to the deep-sea fauna. 
9. Motella macrophthalma , Stur. — Previously known from a depth 
of 80 fathoms ; the specimens obtained on this occasion come from a 
depth of 540 fathoms ; Station 8. 
10. Macrurus, sp. n. ('?). — Two young specimens from Station 4, 
555 fathoms, which have lost the greater part of their scales, approach 
closely M. trachyrhynchus , and may possibly represent only the 
young state of this species. Their snout is conspicuously shorter 
than in a large specimen of the true M. trachyrhynchus, from the 
Mediterranean, but as this may be due to age, I hesitate to give an 
opinion, until I have had an opportunity of examining smaller 
specimens from the Mediterranean. New to the British fauna.
