186 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



Family STEPHANOBERYCID^^. 



Stephanoherycidn; Gill, Standard Natural History, iii, 1885, ]>. 182. (Name only.) 



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

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

 large, thick, oblong, cavernous, witli short convex snout, aud with thin osseous ridges, es- 

 pecially au inner U sliuped one on the crown, whose limbs diverge on each side of tiu; 

 nape; also an outer sigmoid ridge on 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 ojiposite the anterior margin of the orbit. The mouth is very wide and somewhat 

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

 protractile ; suborbitals narrow. Teeth small, in a single band on the intermaxillaries and 

 dentaries ; palatine toothless; Bones of the head usually serrated. Branchiostegals vii-viii ; 

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

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

 fins abdominal, farther back in the adult than in the young, with 1 spine aud 5 rays. 



STEPHANOBERYX, Gill. 

 Slephanoberiix, Gill, Proc. U. S. Nat. Mus., vi, 1883, 238.-Jokdan, Cat. Fisb. 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 



STEPHANOBERYX MON^ — FRONT VTEW. 



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 aud dentaries; i^alate toothless. Ventrals with 1 spine and 5 rays.

Stephanoberijx Monre, Gill, Proc. U. S. Nat. Mus., vi, 1883, 258. 



The ty|)e of the species is a .young specimen, about 2 inches long. For comparison 

 with (V. (}mii we have used examples measuring 4^ inches from Albafro.ss station '2'.i'.)2. 



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

 the head equals one-third of total length to caudal ba.se, the greatest depth of the body 

 two-sevenths of the same length. The upp(>r jaw is slightly longer than the irostorbital 

 part of the head. Gill-rakers long and slender, 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 ventrals originate under the middle of the pectorals. 



Color, brownish. 



Radial formnla: D. U; A. 13-14; P. 10; V. I, 5. 



The type specimen of this species ((3at. No. .33445, TJ. S. iN". M.) was obtained by the 

 Alhatrons from station 2077, in 41'^ 09' 40" N. Lat., Oll^ 02' 20" W. Lou., at a depth of 1,255 

 fathoms. Other specimens were taken by the Albatronn as follows: Prom station 2385, in 28°
