Notes and Co7nments. 



presidential address, ' Some Problems of the Sea,' is, as might 

 be expected, a thoughtful contribution. In it he appeals 

 for more general attention to be paid to marine zoology by 

 teachers and others. Prof. Herdman also writes the Twentieth 

 Report of the Marine Biological Committee, and their Station 

 at Port Erin. And, together with Messrs. Scott and Johnstone, 

 he gives a report on the investigations carried on during 1906 

 in connection with the Lancashire Sea Fishes Laboratory, 

 at the University of Liverpool, and the Sea-Fish Hatchery 

 at Piel, near Barrow. This last occupies 270 pages. 



A MALFORMED GURNARD. 



In this report are several items of interest to the naturalist. 

 In addition to reports on Sea-Fish Hatchery, Tow-netting, 

 Food of Young Fishes, Marked Fish Experiments, Parasites of 

 Fishes, Bacteriological Investigations, etc., there are some 

 useful short notes. These deal with an hermaphrodite Hake, 

 the occurrence of Gadiis esmarkii at Morecambe, a Gurnard 



Deformed Gurnard. 



with a malformed jaw, etc. As will be seen from the accom- 

 panying illustration, this last-named specimen has lost the 

 greater portion of the lower jaw. The upper jaw overhangs 

 the mouth, which is reduced to a small crescentric slit on the 

 lower side of the head, and both jaws were quite immovable. 

 Whatever food the fish obtained must have been of very small 

 fsize. Nevertheless, the fish appeared to be healthy and in 

 good condition.
