were associated eight others and the includiug genus was defined as 

 follows : 



" Cent sixieme f/enre. 



" LES CHEILODIPTi:EES. 



''La levre superieure extensible ; point de dents incisives, ni molares j 

 les opercules des branchies deuues de piquans et de dentelures ; deux 

 nageoires dorsales." 



In 1828, the genus Cheilodiptenis was amended by Cuvier and Valen- 

 ciennes (Hist. Xat. des Poissons, t. 2, p.l62), and restricted to the third 

 species of Lacepkle (le C. rayc) and related species. Inasmuch as (1) 

 the Cuvieriau genus had received no previous name, (2) the Lacepediau 

 name and diagnosis were as applicable to it as to any other of the spe- 

 cies, and (3) it did not conflict with any other rights, there appears to 

 be no sufficient reason for transferring the name to any other genus. 

 Nevertheless, because the first species of the genus was the Blue-fish, 

 Dr. Bleeker has proposed to revive the name Cheilodiptertis instead of 

 Temnodon^ and given a new name [Paramia) for the genus Cheilodij)- 

 terus Cuv. & Yal. ex Lac. Common usage does not seem to justify such 

 a procedure. 



But in 1803 Lacepede described a supposed i^reviously unknown form 

 of fish, the Pomatome skib {Fomatomus sMh), in the following terms :
