The mutual relations of the genera of the Serraninae are indicated in the 

 following table : 



I. Dorsal deeply notched and nearly double. Caudal forked 



and acutely lobed. 



B. 5 (?) Verilus. 



B. 7 Elastoma. 



II. Dorsal nearly or quite entire. 



A. Candal forked and acutely lobed. Dorsal low and uni- 

 form, (IX. 18 19) Brachyrhinus. 



AA. Caudal entire, or simply emarginated. 



B. Body slender. Scales moderate, (50 75.) Teeth not 

 recumbent. 

 Jaws subequal ; preoperculum with a posterior and angular 



group of spines Diplectrum. 



Jaws equal; preoperculum serrated Haliperca. 



Chin prominent. Caeca very few, (2) Mentiperca. 



* The other genera confounded with Serranus and Plectropoma iCuv.) are the follow- 

 ing : Uriphaton, Sw. (Serranus phasion, C. V) Variola, Sw. (S. louti, C. V.) Se.rranichthys, 

 Btkr., Goniopcrca, Gill (S. albomaculatus, Jenyns), Labroperca, Gill (S. labriformis, 

 Jenyns), Mycteroperca, Gill (S. olfax, Jenyns) Serranus, Cuv., Hyporthodus, Gill, Plectro- 

 poma, Cuv., Hypoplectrodes, Gill (P. nigrorubrum, C. V.) Acanthistius, Gill (P. serratum, 

 G. V.) A synopsis of the subfamily may be hereafter expected. 



The Dules auriga and D-flaviventris are probably true Serranina;, and very distinct 

 from D. taniurus and its allies, for which I have proposed the name of Moronopsis. 

 Dides amliguus belongs to still anothf r genus (Plectroplites, Gill) widely distinct from 

 Moronopsis 



t The remaining Lutjaninne appear to represent at least four more generic types: 

 Macolor, Blkr. (Diacope macolor, Cuv. et Val.,) Proamblys, Gill (Diacope nigra, Cuv.,) 

 distinguished by its parabolic profile ; Hypoplites, Gill (Mesoprion retrospinis, Cuv.et 

 Val.) with several strong teeth along the preoperculum below ; and Evoplites, Gill, 

 (Mesoprion pomacanthus, Blkr.) the angle of whose preoperculum has a very stout 

 spine. The differences existing between the other species of Genyorogc {Diacope, C.)and 

 Lutjanus (Mesoprion, Cuv.) appear to be of less value than those between different sec- 

 tions of the combined genera, and are scarcely indicative of natural genera.
