sea faunas would meet in these regions in comparatively shallow 
water. 
Our deep-sea investigations give many examples which tend to 
corroborate this view. 
In the Faroe Channel we have a mixture of abyssal, arctic, and 
modified British forms. Further investigations may show that a 
temperature limit can be drawn within which the British fauna 
should be restricted, but it is at the same time evident that this 
fauna is continuous, on the one hand, with the abyssal, and, on the 
other, with the arctic fauna in the Faroe Channel. 
We desire to acknowledge our indebtedness to the many scientific 
men who have supplied us with information and furnished us with 
reports. 
In the work of the exploration we were throughout assisted by 
Lieut. Hammond, R.N. 
In the practical zoological work we received much assistance from 
Mr. Frederick Pearcey and Mr. James Chumley, assistants on the 
staff of the “ Challenger ” Expedition Commission.

Report on the Fishes. By Dr. A. Gunther, F.R.S. 
This Report was received by the late Sir C. Wyville Thomson in 
November 1880. 
The bathybial fish-fauna which surrounds the British Islands was 
hitherto almost unknown. Besides the stray specimens which now 
and then were found thrown ashore or floating on the surface, no 
further evidence of the existence of this fauna was obtained, except 
on two occasions, viz., on a dredging excursion of Dr. Gwyn Jeffreys 
in 1867, from a depth of from 80 to 90 fathoms and during the 
cruise of H.M.S. “Porcupine” in 1869, from a depth of from 200 to 
500 fathoms. f 
Neither of these two contributions can compare as regards interest
