haabrand) tåken Ihe same day at Frøsetskjerene, Bynesland. 

 The specimen, a d*, had got entanglet ind a coalfish net, and 

 could not get away. The ventricle contained a quantity of 

 otoliths and vertebræ of fish. Collett has found herring and 

 Brosmius brosme in the stomach of hamna. I did not succeed 

 in collecling all the otoliths from the stomach of this Bynes- 

 land specimen, but the preparator Arnold Dircks, took 39 in 

 all. Of these, 26 were from Corypluvnoides rupestris; thus repre 

 senting at least 13 Coryphænoides devoured by the hamna. There 

 were also 6 otoliths of cod, and 7 others probably of coalfish. 



Raja radiata Don. 

 This species (starry ray; Norw. : troldskate) is found through- 

 out the whole of the fjord. During the snurrevad fishery for 

 plaice in the first month of the year, a quantity of egg capsules 

 have also been tåken, which 1 have determined as belonging 

 to this species. Such capsules have especially been found in 

 Gulosen, during the month of February, in net hauls from 2 — 

 100 metres; the appearance of these 1 will now describe. 



Description of egg capsules of Raja radiata. 

 The egg consists of the capsule itself, which is reclangular 

 in form, or occasionally barrel shaped in section (fig. 6). From 

 each corner proceeds a thread, or more properly a tapering 

 tube. The capsule is enveloped in a casing of fine threads, which 

 to some extent mask ils true shape. It consists of a horny sub- 

 stance, the outside covered witha stratum of longitudinal threads. 

 Colour a blackish brown, or al times a lighter brown. There is 

 a lateral keel on eilher side, as in the case of Chimæra mon- 

 strosa. One side of the capsule is almost flat, the other more 

 rounded. Having in this inslance been forlunate enough to lind 

 the ful ly developed young ray in the egg, I can without hesi- 

 tation assert that the flat side is the dorsal, and the domed 

 side the ventral. In several of Ihe capsules from Gulosen V2 

 1910, the conterits had been forced out bj^ the pressure of con 

 tact with the rest of the haul. It occured to me that this might 

 furnish means of ascertaining a line of least resisfance in the 

 capsules, and on examination, I found that the capsules had in 

 all cases burst between the longer terminal tubes, not near the 

 shorl. Furlher, removing the one broad side from an undamaged 

 capsule, I endeavoured lo discover by means of a scalpel where 

 lav the weakest part. As a resull, I found that the scalpel 

 entirely failed to penetrate at the lateral carinæ and near the 

 shorter tubes, whereas a very slight pressure on Ihe edge between 

 the long lubes sufficed. There is thus no doubt that the young
