Gen. XX. Cantharus. — This genus is charac- 

 terised by the teeth being card- like and close set, 

 those of the anterior row being a trifle larger than 

 the others ; their dorsal and anal rays are somewhat 

 more numerous; the mouth is but slightly cleft,

 the American seem to have none. One species is 

 British.

 first described by Colonel Montague, in 1815, under 

 the name of Scarus lineatus^ having been noticed 

 on the coast of Devonshire, where it is by no means 

 uncommon. Duhamel had previously figured it, 

 and it is minutely described in the sixth volume of 

 L'Histoire Nat. des Poissons. The colour of the 

 body is bluish grey, shaded with longitudinal bands, 

 alternately dark and light; the dorsal fin is pale 

 brown, the others of a dusky red colour. Its com- 

 mon size is about fifteen inches, although M. F. 

 Cuvier presented one to the 'Paris Museum which 

 reached to tw^enty inches. Mr. Couch remarks, 

 that it takes the baits common for other fish, but
