370 THE GENERA OF FISHES, PART III 



Chelidonichthys Kaup, 87; logotype Trigla hirundo L. 



Lyrichthys Kaup, 88; logotype Trigla lyra L. A valid subgenus, if Trigla 



GURNARDUS L. is taken as type of Trigla, setting aside the later choice of 



type (Trigla lyra L.) by Jordan & Gilbert, 1883. 

 Palaenichthys Kaup, 90; logotype Trigla aspera Cuv. & Val. A synonym of 



Lepidotrigla Gthr. 



These subgenera of Kaup have been overlooked by authors. They may 



be thus briefly defined, after Kaup : 



a. Scales moderate, evenly placed ; preorbital not produced. 



b. Lateral line armed with strong spines ; dorsal short. Microtrigla. 



bb. Lateral line unarmed ; head well armed. (Lepidotrigla) PALiENicHXHYS. 



aa. Scales very small, crowded. 



c. Lateral line unarmed ; preorbital produced. Chelidonichthys. 

 cc. Lateral line with strong spines. 



d. Preorbital expanded in a broad, emarginate "lyre-like projection." 



Lyrichthys. 

 dd. Preorbital not expanded. Trigla.
