372 "THE ATLANTIC. [CHAP. Y. 
Fra. 104.—Ophioglypha bullata, Wyv1LLE 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. The 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.
