114 Mr. C. T. Regan on the 



bases of the parapophyses at their origin from the centra. 

 Practically the same structure is seen in Kuhlia. 



To the Serranidae I would add Acropoma, which has a sub- 

 ocular shelf, Malacichthys, probably related to Acropoma, 

 and Doederleinia (Ant Mas berycoides, Hilgend.). Two fine 

 examples of this species are in the British Museum Col- 

 lection, and a skeleton has been made of one of them ; the 

 fish is typically Serranid. Diploprion, with 2 anal spines, 

 and Hapalogenys, with toothless palate, are typical Serranids 

 in other characters. Therapon, placed by Boulenger in the 

 Lutianidae, has no pelvic axillary process. 



The Pseudochromididae do not seem to me deserving 

 of family rank. Except for the 2 lateral lines they are 

 typical Serranidae, and Pseudogramma, with the spinous and 

 soft-rayed portions of the dorsal tin subequal, connects 

 Gramma with Pseudochromis and Cichlops. 



Fam. 2. Pseudoplesiopidae. 



The aberrant genus Pseudoplesiops differs from thePseudo- 

 chromidime in that the lower lateral line is absent, the 

 dorsal and anal have but a single spine each, and the 

 articulated rays of the r pelvic fins are unbranched, 4 in 

 number. 



Fam. 3. Plesiopidae. 



General characters of the Serranidae, but the pelvic rays 

 reduced in number, T 2-4, the first soft ray simply bifid. i 

 The genera may be arranged thus : — 



I. Pelvics 14, below or slightly in advance of the pectorals; anal 



spines 3. A subocular shelf. Two lateral lines. 



First soft raj of pelvic not thickened or pro- 

 duced Trachinops. 



First soft ray of pelvic thickened and produced ; 



third and fourth small and slender Plesiops, Paraplesiops. 



II. Pelvics I 2, well in advance of the pectorals, the first soft r.ny 



thickened and produced ; anal spines numerous. No subocular 

 shelf. 



Scales large ; one lateral line Acanthoplesiops. 



Scales small ; 3 or 4 lateral lines Acanthoclinus, 



Fam. 4. Kuhliidae. 



Kuhlia differs from the Centrarchidas in the presence of 



pseudobranchiae, the absence of parietal crests, and the 



different insertion of the ribs. Vertebras 25 (10+15); 



praecaudals with parapophyses from the third or fourth ;
