was found to have a large incurvation in the back (fig. 4). The 

 fish was thick and fat, total length 44 cm., the length of the 

 incurvation at the base of the dorsal fin was 6.5 cm. and Ihe 

 distance from the outor margin of the dorsal fin to boltom of 

 the incurvation 9 cm. This must evidently have been produced 

 by the bite of a sea-otter or of a seal. The wound had healed 

 entirely at the edges, which were nearly rounded, and even pig- 

 mented. The dark colour also extended some little way over on 

 the blind side.

 Some particulars regarding the common dab (Norw.: "sand- 

 flyndre or graaflyndre) will be found in my first report on

tered young specimens of this speeies. In the paper above men 

 tioned, mention is made of a individual 5 cm. long, tåken on 

 the 2 /io 1907 while dredging at Fagernes in Borgenfjord, at a 

 depth of 4 — 13 m. I have also found, among material not vet 

 dealt with, a specimen from Børsa, tåken on the 5/ 5 1899. The 

 total length of the latter specimen was 6.:; cm. Two young spe- 

 cimens, 1. 7 — 8.5 cm. were also tåken in an eel seine in Aavik 

 fjord, Aasen, on the 15 /7 1913. The speeies appears lo thrive 

 particularly well in closed basins such as Borgenfjord and Eids 

 botn, Levanger. Casting with an eel seine at Eidsbotn, on the 

 Vio 1911, we took several specimens. A $, 28 cm. long, had in 

 the ventricle Ophiura albida, Ophiopholis aculeata and Echino- 

 cyamus pusillus.
