Faunistic Investigations. 



Besides carrying out the work of examining the fish 

 caught in the net while on board the steamer a sharp 

 look-out is kept upon the debris brought up along with 

 the fish so that we may know as much as possible of the 

 nature of the food at the bottom, and so that any rare 

 vertebrates or invertebrates that may happen to be among 

 the refuse may not escape notice. It is only by having 

 a thorough knowledge of the fauna of the district that we 

 ean expect to be able to make out accurately the food of 

 the various fishes, for without such a detailed knowledge 

 of the species one would often be puzzled to tell what the 

 fish really are feeding upon, the contents of the stomachs 

 get so much altered during the process of digestion. 



As a result of the untiring zeal of the various members 

 of the Liverpool Marine Biology Committee and other 

 workers it is now no easy matter to make many additions 

 to the fauna of the district, the records during the past 

 year being only 1 Fish, 1 species of Cumacean, 5 species 

 of Copepoda, 1 Ostracod and 1 Sponge. 



The following are the names of the various species 

 referred to, with a note to each of some particulars which 

 may be of interest. 



Fish.

Four specimens of this rare and pretty little fish were 



captured by the trawl-net of the Fisheries Steamer " John 



Fell," while trawling on the off-shore grounds 10 to 12 



miles west from Morecambe Bay Light Vessel during the 



month of May, 1894.
