Eyes lar^ ; irides purple. 1st D. 7, 2d D. 9 ; P. 16 ; V. 7 ; A. 8 ; C. 20. — 
The tail is much forked. 
In reference to the Red Surmullet, M. harbatus^ which for some time has 
occupied a place in the British Fauna, it may be stated, that its claim rests 
on the following vague remark of Mr Pennant. ‘‘We have heard of this 
species being taken on the coast of Scotland, but had no opportunity of exa- 
mining it ; and, whether it is found on the west of England with the other 
species, or variety, we are not at this time informed.” — Brit. JZool. iii. 273. 
No notice, however, is taken of this fish in the list of Scottish animals pre- 
fixed to Lightfoot’s Flora Scotica, and composed by Mr Pennant.
