I 3 6 MARINE AND FRESHWATER FISHES 



repulsive-looking type were imported by the writer, through 

 Messrs. Jeffs and Blake, of Gt. Grimsby, from the North 

 Sea to the tanks of the Manchester Aquarium. Its habits, 

 as there observed in confinement, were found to be essen- 

 tially nocturnal, the fish remaining perfectly quiescent 

 throughout the day on the shingle at the bottom of their 

 tank, but arousing from their lethargy and swimming about 

 in search of food on the approach of night. Preserved 

 specimens and also several casts of fine examples of the 

 Wolf-fish are on view in the Buckland Museum. 



Among the typical Blennies, considerably resembling the 



FIG. 13. SMOOTH BLENNY (Bknnius pholis). 



Wolf-fish in shape, but of relatively pigmy proportions, 

 are the Gattoruginous Blenny (Blennius gattorugieri), 

 No. 75, eight or nine inches long, having two curious 

 antennae-like tufts on the top of its head ; Montagu's 

 Blenny (Blennius galerita), No. 76, two or three inches long, 

 with a single head tuft ; the Butterfly Blenny (Blennius 

 ocellaris\ No. 77> length six or seven inches, and so-called 

 with reference to the elevated, wing-like contour of, and 

 eye-like spot developed upon, the dorsal fin, and lastly, the 

 Shanny, or Smooth Blenny (Blennius pholis), No. 78, whose 

 dimensions nearly accord with those of the last-named 

 fish. Examples of each of these types will be found
