touches, and a small patch opposite the seventh dorsal. The 

 fins do not show the general dusting of pigment seen in the 

 turbot, and thus its condition corresponds with Raffaele's 

 drawings of the brilP. 



Another of 24 mm. comes, on the 25th of the same month 

 (July), from the tidal margin of the estuary of the Eden. In 

 coloration it corresponds with the brill, but the right side has a 

 general distribution of blackish chromatophores. The right 

 eye is not so far to the left as might have been anticipated, for 

 the dorsal fin has not reached the central line of the eye. 

 The dorsal has 74 rays, and the anal 56 to 57 rays. The 

 spines have disappeared. 



In August, those captured ranged from 22 to 29 mm. The 

 former, which also occurred in the hand-net at the tidal margin 

 of the Eden, has a general resemblance to a brill. A hard patch 

 occurs on each otocyst. The pigment is as in the foregoing 

 specimen. Both eyes are on the left, and the dorsal fin has 

 advanced to the mid-ocular region. The dorsal has 75 rays ; 

 the anal has 54. The example at 29 mm. was procured in the 

 trawl on the 20th August, and also is brill-like. The right 

 side still has many blackish pigment- specks, as in the younger 

 forms. Each otocyst has a hard patch. The dorsal fin has 

 advanced considerably in front of the right eye, which is 

 separated by a distinct space from the fin. The dorsal has 

 75 or 76 rays, the anal 59. Scales are not yet developed. 

 Petersen found the number of fin-rays in brill from 11 to 

 182 mm. to be, for the dorsal 70 — 80, most having 73 to 75 ; 

 for the anal, 51 to 60, most having 53 — 56°. 



In September specimens of 50 and 61 mm. occurred in the 

 seine or sand-eel net on the East sands, St Andrews. They are 

 apparently miniature adults, though in the smaller the curve 

 of the lateral line anteriorly was faintly marked. These would 

 probably be in their fourth or fifth month. 



At Plymouth examples in October ranged from 2'8 to 3'9 

 inches, and as they were reared by Mr Cunningham in the 

 aquarium, there can be no dubiety about their age (6 months).
