only species of whose affinity I entertain any doubt is the S. elongatus Ayres ; 

 that species, however, appears to be either a Sebastichthys or closely related 

 to that genus. As to the number of species, I am disposed to doubt whether 

 all are valid or even distinct from each other ; the S. helvomaculatus Ayres 

 appears to be identical with S. ocellatus Cuv. et Val. As Dr. Ayres kindly 

 announces his intention to forward a full series, I trust soon to be enabled to 

 satisfy myself regarding such doubtful points. 



1. Sebastichthys jiigrocinctus = Sebastes nigrocinctus Ayres. 



CARANGOIDS. 

 Paratractus Gill.* 

 Paeatkactus bcops. Syn. Trachurus boops Grd. 



GOBIOIDS. 



Eucyclogobius Gill. 

 Eacyclogobius differs from Lepidogobius in form, nudity of the head and 

 the smaller second dorsal fin. 



2. Eucyclogobius Newbekkyii. Syn, Gobius Newberrii Girard. 



GOBIESOCOIDS. 



Caularchus Gill. 

 The present genus differs principally from Gobiesox Lac. (= Sicyogaster 

 Barneville) by the nearly equal size of the dorsal and anal fins, and the 

 nearly horizontal direction of the six compressed trenchant incisors of the 

 lower j aw. 



3. Caularchus eeticulatus. Syn. Lepodogaster reticulatus Girard. 



CYCLOPTEROIDS. 



EUMICROTREMUS Gill. 



Differs from Cyclopterus Artedi by the smaller branchial apertures situated 

 at the horizon of the eyes, and by the development of the spinous dorsal fin. 

 The type is the Cyclopterus spinosus of Midler. 



Eumicrotremus orbis. Syn. Cyclopterus orbis Gthr. 



SALMONOIDS. 

 Hypsifario Gill. 

 This genus embraces a single known species, distinguished by its com- 

 pressed body, projecting snout, &c. 



Hypsifario kennerlyi. Syn. Salmo kennerlii Suckley. 



PLEURONECTOIDS.f 

 Lepidopsetta Gill. 

 Lepidopsetta umbrosa = Psettichthys umbrosus Grd. 



Hypsopsetta Gill. 

 Hypsopsetta guttulatus = Pleuronichthys guttulatus Grd. 



Orthopsetta Gill. 

 Orthopsetta soedida = Psettichthys sordidus Grd. 



TJropsetta Gill. 

 Ueopsetta californica = Hippoglossus californicus Ayres. 



* Type Caranx pisquetos C. V. = C. chrysos auct. nee Mite. 

 t A synopsis of this family may be soon expected.
