Hippoglossus hippoglossns Lin. 

 Large halibuts (Norw. : »storkveite«) are occasionally tåken 

 in the Trondhjem Fjord, especially on the Mefjordsgrund between 

 Munkholm and Tautra; the fishery appears, however, on the 

 whole to have declined. At Strømmen, Inderøya, quantities of 

 halibut were tåken about 1860. Even in Borgenfjord, which has 

 a maximal depth of only 37 in., large halibut have at times 

 been caught. In 1910, an octogenarian by name Amund Gustad 

 eould remember that his father had once tåken a halibut vveigh 

 ing 7 »vog« (1 vog = 18 kg.) off Rolshavn. It had got caught 

 by the tail in the plaice-nets. This must have been about 1840. 

 And in the 90's, another halibut of 5 vog was tåken in Borgen- 

 fjord. It had got entangled in some ordinary lines, and could 

 not use its gills. Small halibuts (called »kveitebarn«) are how- 

 ever, not infrequently caught. The staff of the Biological Station 

 have of late years tåken several such in Orkedalsfjord, in the 

 course of the plaice fishery which is carried on with the snurre 

 vad after Christmas. 



Hippoglossoides platessoides Fabr. 

 The long rough dab (Norw.: »langkjeftflyndre«) has been 

 tåken now and again during the plaice fishery for the hatchery; 

 I have not, however, made any close investigation of the spe 

 eies. It goes right up into the Beitstadfjord; on the 8 /s 1906, 

 while dredging in the Verrafjord, we took a young specimen 1. 

 9.5 cm. Three small specimens were also tåken in Muruviken 

 on the 17 /2 1914. L. 11 — 12.5 cm. Dr. Swenander took a year 

 ling of 4.4 cm. in Buviken 17 /s 1904. 



Bothus maximus Lin. 

 The turbot (Norw.: »sandkverv« or »pighvarr«) has long 

 been a well-known species in Trondhjem Fjord; altough little 

 has been known as to its propagation in these waters. On the 

 31 /7 1911, however, during an excursion from the Biological 

 Station, we came across a couple of young fry of these species, 

 at the surface of the water, near Tautra (Pl. II, Figs. 8, 9). 

 They were thus living in a planktonic state. The smaller spe 

 eimen measured 13.5 mm. and exhibited almost uniform pig 

 mentation on both sides, each side being closely covered with 

 black spots. The right eye somewhat nearer the dorso-ventral 

 plane than the left. Incipient spinous armament on the gill 

 covers. The other measured 22 mm. total length. The left side 

 was here more strongly pigmented than the right, on which 

 latter the pigmentation mainly consisted of small dark spots, 

 whereas on the left, these had in places collected into larger
