120 THE BERGYLT-FAMILY. 



for the yolk projects in front like a prow with the oil-globule at 

 the tip, and the vent is close to its posterior border, while 

 sparsely distributed black stellate pigment occurs along the 

 dorsum and sides. By the second day the prow of yolk has 

 been considerably abbreviated, and a larger space exists between 

 the vent and the receding yolk, while the /"-shaped curvature 

 which characterised the newly-hatched fish is now scarcely 

 noticeable. The usual extension of the marginal fin forwards 

 to the mid-brain and the appearance of larval sense-organs 

 have also taken place. Between this and the 7th or 8th day 

 the yolk has entirely disappeared (Plate V, fig. 6), and the 

 black pigment has grouped itself chiefly along the ventral 

 border of the muscle-plates with a very little on the side above, 

 in the middle of the body, and a speck above and below the 

 plates about a sixth from the tip of the tail, and also along 

 the abdominal roof. The eyes are richly pigmented and re- 

 splendent. In the middle of June, and in July and August, 

 Raffaele also found young fishes (2 3 cm.) with a barbel and 

 silvery aspect, for the roseate colour had not yet appeared. 



In the young examples described by Malm 1 the profile of 

 the head is almost like that of the cod, but as it increases 

 in size the interorbital space rises so as to give it the charac- 

 teristic form of the adult. Cunningham mentions that young 

 examples, 3 inches long, occur in Plymouth Sound in summer. 

 He considers them a year old.

THE NORWAY HADDOCK. (Sebastes marinus, L.) 



As one of the two British viviparous forms amongst bony 

 fishes this species is of special interest, though few opportunities 

 have been had of examining it, the only specimen in the collec- 

 tion at St Andrews having been obtained from Mr Sim, of 

 Aberdeen. It was brought from the Moray Frith, where it 

 occasionally occurs. It is common off the Norwegian shores.
