Nr. 9] CONTRIB. TO THE LIFE HISTORY OF THE FISHES 15 



so many other deep waler spedes, Ihis fish also furnishes its 

 Iribute to the food oi the shark. On the Vu 1907, a Greenland 

 shark, ?, 1. 245 cm., was tåken in Mnnkholmdyb, with remains 

 of Molua dipterygia in the ventricle. 



Raniceps raninus Lin. 

 The lesser fork-beard (Norw.: »paddetorsk«) seems also lo 

 be of rare occurrence on the Trondhjem Fjord. A specimen 

 was tåken at Ladehammer on the 2 /4 1910 and placed in an 

 aquarium. At the end of May, it took a bening, which it was 

 three days digesling, the herring parlly protruding from ils 

 mouth during that time. On the 6 /n 1914 another specimen 

 was tåken at Strindland. This was a d\ 1. 24.5 cm. with sperma 

 running. Nothing determinable in the stomach. 



Coryphænoides (Macrurus) rupestris Gunn. 

 This species (Norw.: »butnæse«) is one of those frequently 

 laken on lines in the deep channels and depressions of the 

 fjord. It goes right up as far as Beitstadfjord; a specimen 1 

 metre long was tåken just before Christmas 1915 in a net 1000 

 metres S.W. of Vaggen. I have from time to lime seen quite a 

 number of specimens brought in from Munkholmdyb. In the 

 ventricle of Coryphænoides from this water tåken on the ]8 /i 

 1916, I found several specimens of Pasiphæa multidentata Esmark 

 (this Pasiphæa had a wedgescaped upright rostrum, and must 

 thus be multidentata. Vide O. Sundt, The glass shrimps in 

 northern waters; Bergens Museums Aarbog 1912 No. 6) including 

 a few females with roe. There were also several Meganyctiphanes 

 norvegica M. Sårs, as also Parathemisto oblivia Kroyer. I have 

 previously found Parathemisto in the ventricle of Lofoten » skrei 

 (i. e. cod which have attained maturity; vide Johan Hjort: 

 Fluctuations in the Great Fisheries of Northern Europe, Rapp. 

 et Proc. Verb. du Cons. Perm. Intern, pour 1'Explor. de la Mer 

 Vol. XX Copenhagen 1914, p. 3 footnote) 16 /s 1897, at Svolvær 1 , 

 as also in coalfish 2 herring s and Myctophum glaciale i . A female 

 of C. rupestris, tåken on a long line off Ambornes 27 /n 1907, 

 was spent. This agrees with Swenander's statement that spawn- 

 ing takes place in September and October.
