262 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



lu a linguiform lobe. The veiitrals are directly under the axils of tlie pectorals, with the 

 outer rays produced, thick and branched. 



This genus has as yet been found only in the Pacific. Tlie type is Sdiastolohus macro- 

 chir (Giinther) Gill, (Cliallenger Report, i, 1880, part vi, 05, PI. xxvii), obtained by the 

 (Jhallctujer off Inosiina, at a depth of 345 fathoms. Another species, 8. alancaiiu.s, Beau 

 (Proc. U. S. Nat. Mus., xiii, 1890, -H), was obtained by the Albatronx at station 2853, off 

 Trinity Islands, Alaska, in N. Lat. 56°, W. Lou. 154°, at a depth of 159 fathoms. 



SEBASTODES, GUI. 

 Sebaslodes, Gill, Proc. Acad. Nat. Sci. Phila., 1863, L'07. 



ScoriJibuitls with the dorsal continuous, though somewhat notched, and with thirteen 

 spines in the dorsal and nine rays in the anal. Skull thick and cranial ridges weak. 

 Lower jaw much projecting. Teeth in villiform bauds on jaws, vomer, and palatines. 

 Scales small, ninety to one hundred in the lateral line. 



This genus is represented by a single species, S. paucisjnnis, (Ayres), Jordan and Gil- 

 bert, found on the coast of California " in rather deep water." DeeiJ-sea representatives of 

 the genus should be looked for on oiu' Northwest coast. 



SEBASTICHTHYS, Gill. 

 Sebastichthys, Gill, Proc. Acad. Nat. Sci. Phila., ISOa, 207. 



Scorpaenids with the dorsal continuous, though somewhat notched, and with thirteen 

 spines in the dorsal and five to nine in tlie anal. Skull thick and cranial ridges weak. 

 Lower jaw projecting but slightly. Teeth in villiform bands on jaws, vomer, and palatines. 

 Scales moderate, forty-five to eighty in the lateral line. 



This genus is represented on tlie Nortliwest coast and adjacent deep waters by forty 

 or more species, nine or ten of these having been described as new by Gilbert,* from the 

 bathybial fauna explored by the Albatross in 1888. These occur outside the 100-fathom 

 line, and to as great a depth as 26G fathoms. As might have been expected, the genus 

 of bottom-living fishes most abundant in species and numbers along the shores of this coast, 

 has contributed the largest quota to the inshore deep-water fauna of the adjacent ocean. 



SETARCHES, Johnson. 

 Setarches, Johnson, Proc. Zool, Soc. London, 1862, 176. — .Jordam and Gilbert, Bull, xvi, U. S. N. M., 682. 



Scorpseuids with head and body compressed, the head flat between the eyes, with sev- 

 eral low ridges. Head scaleless, its bones cavernous. No transverse groove on the occiput. 

 Preoperculum and operculum strongly armed with straight, long spines. Eye moderate, 

 near but not touching the profile. Mouth terminal, broad, somewhat oblique, the posterior 

 edge of the maxillary extending to opposite the posterior part of the eye, and iiuicli 

 expanded. Lower jaw somewhat projecting, with knob at symphysis received in rostral 

 notch. Villiform teeth in jaws, on vomer and palatines. 



Operdes scaly. Scales cycloid, moderate. Lateral line a broad, scaleless groove, with 

 a series of skinny tubes. No laciniie. 



Dorsal fin deeply notched, so as to appear in two portions; dorsal spines 10-1, the soft 

 portion of the fin shorter, and with rays fewer than spines. Anal with 3 strong spines 

 inserted under the end of the dorsal. Pectoral fiii broad and long, with 20 or more rays, 

 of which a considerable number of the medial ones are branched. Branchiostegals or 7. 

 Pyloric appendages few. No air bladder. 



The type is Setarches Giiitlhcri (Johnson), from Madeira, undoubtedly from deep water, 

 since only one specimen appears to have ever been taken. The genus Lioscorpms (Giinther) 

 can scarcely be distinguished from Setarches.
