smaller, from which they conclude that the large fish assume the dominion of a 

 district, and keep the younger at a distance." The gold sinny (Crenilabrus 

 melops) is a British example of a second genus, distinguished by the serrated edge 

 of the preopercular. Another well-known member of the family is the black-fish 

 (Tautoga onitis), of the Atlantic coast of North America, so named on account of 

 its blackish brown colour, and the sole representative of a genus characterised by 

 the naked opercular, the rudimental scales on the cheek, and the double row of 

 teeth in the jaws.

 in front of the upper. Of the splendidly coloured Mediterranean species Dr. 

 Oiinther writes that "it was most plentiful and of the best quality in the 

 Carpathian Sea, between Crete and Asia Minor, but was not unknown, even in 

 early times, on the Italian coasts, though Columella says it seldom passed beyond 

 Sicily in his day. But in the reign of Claudius, according to Pliny, Optalus 

 Elipentius brought it from the Troad, and introduced it into the sea between 

 Ostium and Campania. For five years all that were caught in the nets were 

 thrown into the sea again, and from that time it was an abundant fish in that 

 locality, In the time of Pliny it was considered to be the first of fishes ; and the 

 expense incurred by Elipentius was justified, in the opinion of the Roman 

 gourmands, by the extreme delicacy of the flesh." This fish feeds 011 seaweed; 

 and the mastication required to reduce this to a pulp probably gave rise to the old 

 idea that it was a ruminant.
