COMBER, Serranus cabriUa. 



One specimen oi Serranus cabrilla, 22-5 cm. in length, was 

 landed 18th November, 1915, by a North Shields trawler from 30 

 miles N.E. of the Tyne. The scales have the winters similarly 

 marked to those of the bass and ballan wrasse, and also indicate 

 a complete stoppage of growth during the winter. This stoppage 

 is not so clear in the area occupied by the radiating grooves, but 

 is very strongly marked in the lateral portions of the scales by 

 the condition of the concentric ridges, which are not parallel to 

 the edge of the scale, especially in earlier years, and are inter- 

 rupted each winter. 



Calculations made from the scales give a growth as follows : — 



Years ... 1 2 3 4 5 



Size ... 6-3 12-3 18-1 21-6 22-5 cm.
