SEA-FISHERIES LABORATORY. 215 



Mytilus, '3 to '42 millimetre in length and '26 to 

 '36 millimetre broad, were noted in the bottom tow- 

 netting from Section I. on June 10th. They were also 

 found at the surface and bottom on July 12th. Many of 

 these were probably just at the point of " striking." A 

 few that had apparently " struck," and afterwards became 

 detached from their anchorage, showed a considerable 

 increase of shell, the more recent portion being distinctly 

 defined from the older by its greater transparency. These 

 young mussels were also noted at the surface in Section 

 II. on July 18th, and in Section YL, at the surface, on 

 July 28th. 



(8) Young fishes. ~No newly-hatched fishes were met 

 with. Post-larval stages were scarce. The young forms 

 noted had probably come to the surface to feed. One 

 post-larval Cottus was taken at the surface in 

 Section II. on June 9th. One post-larval Gadoid in 

 Section YL on May 10th. One young yellow gurnard, 

 taken at the surface in Section Y., September 3rd; one 

 10 millimetres long in Section YII. on August 2nd ; one 

 9'5 millimetres long at Port Erin on June 4th. One 

 young garfish (Belone), 20 millimetres long, with upper 

 jaw undeveloped, in Section YI. on July 14th. Eight 

 " Mackerel midges," 10 millimetres long, in Section YII. 

 on June 26th. These were made out to be young rockling, 

 Onus trieirratus. One Gadoid, 32 millimetres long, in 

 Section YII. on July 15th. Two young weevers 

 (Trachinus) in Section YII. on August 2nd. Twelve 

 young Gadoids, T'5 to 10 millimetres long, at Port Erin 

 on June 4th- -their stomachs were filled with Copepods.
