 from Albatross station 5066, in Suruga Gulf, Japan, collected on 

 October 15, 1906, at a depth of from 211 to 293 fathoms. 



Length of head, from tip of rostral hook to upper angle of branchial 

 aperture, 0.17 of total length to base of caudal; depth of body, 0.27; 

 dorsal, 112; anal, 96; caudal, 12; ventral, 4; 105 series of scales be- 

 tween upper angle of branchial aperture and caudal base, 47 in a trans- 

 verse series between first anal rays and the dorsal fin. 



Head rather evenly rounded, the snout being nearly vertical from 

 the tip of rostral hook to origin of dorsal; eyes small, the upper 

 slightly in advance of the lower, its diameter 0.03; interorbital nearly 

 obsolete, with a few scales, a few scales also on eyeball; length of 

 snout from upper orbit to tip of rostral hook, 0.05; anterior nostril of 

 eyed side in a slender tube, its length about half the diameter of eye, 

 placed midway on a line joining the posterior nostril and tip of rostral 

 hook, posterior nostril of eyed side between anterior margins of 

 orbits, opening through abroad, rather low tube; nostrils of the blind 

 side similar to those of eyed side, the anterior with a shorter tube, the 

 posterior with an anterior flap; mouth strongly curved, small, the 

 maxillaries reaching to below anterior edge of lower pupil ; length, 0.04; 

 teeth very slender and sharp, in a band of about four rows confined 

 to the blind side of jaws. 



Body elongate-elhptical, moderately compressed, its width about 

 5 in its depth; tip of mandible to anus, 0.22; anus on blind side; 

 depth of caudal at base, 0.04. 



Scales ctenoid on both sides. Lateral line absent, the median line 

 slightly grooved. 



Origin of dorsal on snout in advance of upper eye about three-fourths 

 of its diameter, the first rays well separated, becoming more crowded 

 posteriorly, so that there are only 1 1 rays anterior to the vertical of 

 the upper angle of branchial aperture, while there are 24 rays in the 

 same length of base at the end of the ^n ; height of dorsal nearly uni- 

 form, 0.07; anal similar, the first 2 rays thickened and joined; length 

 of caudal, 0.09, rather pointed; ventral fin single, on the preanal 

 ridge, deflected toward the blind side under the united gill membranes. 



Color of both sides uniform brown, the snout and caudal fin pale, 

 the dorsal and anal fins dusky, the ventral fin pale ; peritoneum black, 

 showing distinctly through body. Color of S. orientalis, as described 

 by Bleeker: 



Color of the body on the eyed side dusky-green, median opercular region with a 

 diffuse band, trunk diffusely and darkly clouded and transversely subfasciato; fina 

 dusky, ventral somewhat yellowish; iris greenish-yellow; color of blind side whitish;
