caught in January 1884. This specimen must of necessity be at least 

 one year and five months old, but is probably 2 years and 5 months. On 

 21st July 1884, one which measured 155 mm. was obtained. The age of 

 this individual must be at least one year, and perhaps is about two years 

 and one or two months. The latter age is the more likely. There are 

 no preserved specimens to fill up the great gap between the specimen 25 

 mm. long and those captured in August, 133 and 137 mm. long. The 

 lemon dabs, measuring respectively 154, 156, and 172 mm., caught in 

 August, are probably about two years old. The specimens, 133 and 

 137 mm. long, trawled in August, are at least one year old, but may be 

 two years old. 133 mm. (5*3 inches) appears to be too great a size to be 

 reached by the lemon dab in one year. The length of this form when one 

 year old is not therefore likely to be more than 90 mm. (3*6 inches). The 

 examples 180 and 183 mm. respectively, captured in May, may be reckoned 

 about two years and nine months old; and the specimens 198 and 208 

 mm. obtained in August probably are about three years.
