The "Witch has been taken at a maximum depth of 315 fathoms on this coast. It is 

 not possible to define a habitat of the immature as apart from that of the mature, but 

 it appears that the younger stages never come so near the shore as some of the latter. 

 Very few seem to get above the 20 fathom line. It is noticeable that this fish spawns 

 in deep water, and that the young are found there, as in the case of the Hake and 

 some other forms, whereas in the case of the Turbot, which is supposed by Fulton to 

 spawn in comparatively deep water, and at great distances from land, the young are at 

 all events frequent in very shallow water. 



The first dotted line indicates Fulton's limit. The second line shows what I am 

 inclined to think is the limit of mature females. 



SCALDFISH — Arnoglossus laterna. 

 Specimens are taken as follows: — In April, 1, 4f inches, at 25 to 20 fathoms off 

 Gregory Sound; 1, 4| inches, at 25, 1| to 2J inches, at 15 fathoms, in Galway Bay; 

 I, 2 inches, at 5 fathoms, in Blacksod Bay. In May, 1, 2 J inches, at 3 fathoms, in 

 Teelin Harbour; 7, 2J inches, 2, 4| inches, 1, 5 inches, at 3 fathoms, off Rossnalegh 

 Point, Donegal Bay. In August, 5, 3^ inches, at 14 fathoms, in Galway Bay, and 4, 

 1 inch, and 6, 4 inches, at 41 fathoms, on the Nymph Bank, Ballycotton. It thus 

 appears that this fish is pretty generally distributed along the coast, always in rather 

 shallow water, and there is no apparent difference in the haunts of the young and the 

 older stages. Cunningham records that they are exceedingly abundant at "all sizes 

 from about three quarters of an inch long up to the full size of about 6 inches " in 

 Cawsand Bay, Plymouth Sound, where they are looked upon by local fishermen, in 

 common with the solanette, as the young of the common sole. 



BKOAD SCALDFISH — Arnoglossus grohmannii. 

 A specimen of 5 inches was trawled at 6 fathoms in Clifden Harbour, between the 

 anchorage and the north shore, on the 11th June, 1890. Three young examples, If to 

 If inches, occurred at 4 to 5|- fathoms in the Inner Harbour, Killybegs, on the eastern 

 side near the entrance, on the 16th May, 1891. This species was previously known 

 in British waters from a specimen taken by Mr. Green, in the Kenmare River, and 

 another described by Mr. Cunningham, from Cawsand Bay. It seems to affect shallow
