A third haul, on this same occasion (October 27th) gave 

 us, from 16 fathoms, 156 species (see below, p. 34). 



In order to get another case, on entirely different 

 ground, not of our own choosing, on the first occasion 

 after the publication of Dr. Murray's volumes when 

 we were out witnessing the trawling observations of the 

 Lancashire Sea-Fisheries steamer "John Fell," I counted, 

 with the help of Mr. Andrew Scott and the men on 

 board, the results of the first haul of the shrimp trawl. 

 It was taken on July 23rd at the mouth of the Mersey 

 estuary, inside the Liverpool Bar, on very unfavourable 

 ground : bottom muddy sand, depth 6 fathoms. The 

 shrimp trawl (1^-inch mesh) was down for 1 hour, and 

 it brought up over seventeen thousand specimens referable 

 to the following thirty-nine species belonging to thirty- 

 four genera : — 



Solea vulgaris
