Family STEPHANOBERYCID^E. 



Stephanoierycidcp,, Gill, Standard Natural History, lU, 1885, p. 182. (Namo only.) 



Body oblong, compressed, with scales of peculiar form, circular, having in the center of 

 each, one or two erect, conspicuous spines, aiul in arrangement scarcely imbricated. Head 

 large, thick, oblong, cavernous, with short convex snout, and Mith thiu osseous ridges, es- 

 l>ecially an inner U-shaped one on the crown, whose limbs diverge on each side of the 

 nape; also au outer sigmoid ridge ou each side above the eyes, continuous with a similar 

 ridge projecting from the nasal bone, the inner and outer ridges being (connected by a cross 

 ridge opposite the anterior margin of the orbit. The mouth is very wide and somewhat 

 oblique. Lower jaw slender and slightly projecting. Maxillaries large; premaxillaries 

 pi'otractile ; suborbitals luirrow. Teeth small, in a single band on the intcrmaxillaries and 

 dentaries ; palatine toothless. Bones of the head usually serrated. Branchiostegals Vli-Vill; 

 gill membranes separate, 3; gills 4, a slit behind the fourth. Pseudobranchiaj present. 

 Gill-rakers moderate. A single dorsal. Dorsal aud anal without spinous rays. Ventral 

 lius abdominal, farther back iu the adult than in the young, with 1 spine aud o rays. 



STEPHANOBERYX, Gill. 



Stephanoberiix, Gill, Proc. II. S. Nat. Mus., vi, 1883, 258.-Jord.^, Cat. Fish. N. Amer., 1885, 74. 



Berycids with an elongated claviform contour, body covered with cycloid scales, scarcely 

 imbricated, and armed about the center with one or two erect spines. An oblong head, 

 with a moderate, convex snout, and with thin osseous ridges, especially an inner U-shaped

one on the crown, whose limbs diverge on each side of the nape, and an outer sigmoid one 

 on each side above the eyes, and continuous with one projecting from the nasal; the inner 

 and outer ridges connected by a crossbar on a line with the anterior margin of the orbit; 

 rather small eyes in the anterior half of the head, and the teeth small, acute, and in a band 

 on the intermaxillaries and dentaries; palate toothless. Veutrals with 1 spine and 5 rays.

The type of the species is a young specimen, about 2 inches long. For comparison 

 wltli S. OUlii we have used examples measuring 4 J inches from Albatross station 2392. 



In one of these the eye is two-ninths as long as the head and nearly equal to the snout; 

 the head equals oue-third of total length to caudal base, the greatest ilepth of the body 

 two-sevenths of the same length. The upper jaw is slightly longer than the postorbital 

 part of the head. Gill-rakers long and sleiuler, about 25 below the angle on the first arch. 

 The distance of the anal origin from the end of the head equals two-thirds length of head. 

 The veutrals originate under the middle of the pectorals. 



Color, brownish. 



Kadial fornuila: D. 14; A. 13-14; P. 10; V. I, 5. 



The type specimen of this species (Cat. No. 33445, TJ. S. N. M.) was obtained by the 

 Albatross from station 2077, in 41^ 09' 40" N. Lat., (ilP 02' 20" W. Lon., at a (lei»th of 1,255 

 fathoms. Other specimens were taken by the Albatross as follows : From station 23S5, in 28°
