fl. Gill arches -with obsolete or no rakers.

 pectinate. 

 d. Preventral region transversely convex and not distinctly limited.

 keel extending from the pectoral to the outer ray of the ventral.

In other teims, while the typical Curimatiue series has lost the gill] 

 rakers, it has diverged most in other respects from the common pro-J 

 geiiitors, while ElopomorpJins has developed gill rakers of increased size 

 and added other striking characters. In a genealogical table the snpl 

 posed facts may be thus represented : 



Cnrimatavus. 



Cnriuiatopsis. 



Cniimata. 



I'sectvogiister. Potauiorhina. 



Klopomorphus.

The chief of the Curimatine genera has been generally called Cnrima- 

 /ws, but the name should be spelled Cnrimata, as the following early 

 synonymy shows : 



'For all other characters, see Steindachner, Ich. Beitr., V, j). 34, 1876. 

 I have accepted the genera and, in several cases, the language of Professor and 

 Mrs. Eigeumann, who, in the analysis of their valuable Pevision of the Edentulous 

 Genera of Curimatina', have arranged the genera in the following se(iueuce: 

 Anodus ( := EJopomorplms), rotamorhina, Psecfrogasler, Ciirintatopsis, Cin-'tmafiis. 

 Later they adopted the name Elopomorplms in place of Anodus (Proc. P. 8. Nat. 

 Mus., XIV, 1891, p. 46).
