Macrurus Icevis. 

 Sixteen examples, 10 to 21J inches, were trawled at 220 and 144 fathoms, 40 and 

 30 miles off Achill Head, on the 4th July. One of 15 inches occurred at the former 

 depth 50 miles off Bolus Head, on the 23rd March, and eight, about the same size, at 

 154 fathoms, 26 miles off Achill Head, on the 20th April. Specimens were previously- 

 taken off the S.W. coast at 200 to 250 fathoms, by the "Flying Fox" and "Ee- 

 search." The species may be said to be cosmopolitan. It is known from Madeira and 

 the Mediterranean, and examples have been recorded from the coast of Denmark 

 (Liitken), off Pernambuco (Challenger), and from the Andaman Sea (Alcock). The size 

 of our largest specimen appears to represent the full dimensions, as far as they are 

 known. 



LONG EOUGH DAB — Hippoglossoides Umandoides. 



This table points to the fact that the younger stages of existence are passed in deep 

 water, the fish gradually approaching the shore as it grows older. Fulton on the East 

 coast of Scotland found hardly any very small specimens at a less depth than 12 

 fathoms, the majority being in about 20 fathoms, and some occurring at 55 fathoms. 



This table, so far as it goes, appears to show that no mature Turbot penetrate into 

 quite such shallow water as some of the immature forms, and also that no immature 

 forms get into such deep water as a proportion of the mature. It would also appear 

 that the closing of waters within the 10 fathom line would protect a very large propor-
