THE ATLANTIC. 



[chap. v. 



Pig. lOi.—Ophioghipha bullata, Wyville Thomson. Dorsal aspect. Three times the natural 



size. (No. 54.) 



bullata is a species of great interest on account of its wide dis- 

 tribution at extreme depths. It seems universally distributed 

 in the Atlantic and the Southern Sea. Tlie trawl which we 

 used on this occasion had a beam of eighteen feet long, and as 

 we calculated that it had been dragged for at least a mile over 

 the bottom, it gave us a fair idea of the distribution of the large 

 forms of animal life over a considerable area.
