indications that growth of the present summer zone was beginning 

 were to be seen on most of the otohths examined. 



The scales in some cases are useful to check the reading obtained 

 from the otoliths, but as a rule they are difficult to read. From the 

 number examined it would appear that it is only in the case of 

 fish small for their age that the winter areas on the scales are 

 strongly marked and easily read. The scales of one fish, 52 cm. 

 long, and landed 18th March, had six winter areas most distinct,

 were as follows : —

LONG ROUGH DAB, Hippoglossoides limandoides. 

 The fish examined were found amongst a sample of small 

 dabs and plaice caught in Blj^th Bay, 28 to 30 fathoms, 17th April, 

 1916.
