2G2 DEEP-SEA FISHES OP THE ATLANTIC BASIN. 



ia a linguiforin lobe. The ventrals are directly under the axils of the pectorals, with the 

 outer rays produced, thick and branched. 



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

 ehir (Giinther) Gill, (Challenger Report, i, 1880, part VI, 65, PL xxvii), obtained by the 

 Challenger off Inosiina, at a depth of 34.5 fathoms. Another species, 8. alascanus, Bean 

 (Proc. U. S. Nat. Mus., xiii, 1890, 44), was obtained by the Albatross at station 2853, off 

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



SEBASTODES, Gill. 

 Sebastodes, Gill, Proc. Acad. Nat. Sci. Phila., 1863, 207. 



Scorpsenids 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 bands on jaws, vomer, and palatines. 

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



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

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

 the genus should be looked for on our Northwest coast. 



SEBASTICHTHYS, Gill. 

 Sebastichthys, Gill, Proc. Acad. Nat. Sci. Phila., 1863, 207. 



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

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

 Lower jaw projecting but slightly. Teeth iu villiform bauds on jaws, vomer, and palatines. 

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



This genus is represented on the Northwest 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 266 fathoms. As might have been expected, the genus 

 of bottom-living lishes 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.— -Jordan and Gilbert, Ball, xvi, U. S. N. M., 682. 



Scorpsenids 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 much 

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

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



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

 a series of skinny tubes. No lacinise. 



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 fin broad and long, with 20 or more rays, 

 of which a considerable number of the medial ones are branched. Branchiostegals 6 or 7. 

 Pyloric appendages few. No air bladder. 



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

 since only one specimen appears to have ever been taken. The genus Lioscorpius (Giiuther) 

 can scarcely be distinguished from Setarches.
