Habitat. — Mediterranean Sea. 



This speeies is known to us from specimens in the Museum of Com- 

 parative Zoology, from Cette (Theodore Lyman), and from Cadiz (Dr. 



Steiudachuer). It does not seem to be very common anywhere.

We here include in the genus Pleuronectes three species, the Turbot, 

 the Brill, and the " Wiudow-Pane." The Turbot and the Window- 

 Pane are both evidently very closely related to the Brill, although in 

 size and appearance they are quite unlike each other. The Turbot 

 differs strikingly from the other two in a single character, the reduced 

 or rudimentary condition of the scales. This character, however, shows 

 a considerable range of variation in the same species, some turbo ts 

 being distinctly scaly and others wholly naked, and it is apparently a 

 character which the species has acquired comparatively recently. We 

 have therefore regarded it as of subgeneric value only. We, however, 

 place the two scaly species in a distinct subgenus, Bothus, and in the 

 view of a genus taken by many recent authors, Bothus aud Pleuronectes 

 should be regarded as sufficiently distinct. If the non-binomial names 

 of Klein, as reprinted or revived by Walbaum in 1792, be admitted.
