334 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



Mnciferous pores large, arranged mncli as in B. catena. 



Dorsal orijiiii ia the sanie vertical with that of the pectorals, its distance from the tip 

 of the snout (38 millimeters) contained 5 times in total and equaling twice the length of 

 the maxilla. Kays well deveh)ped in the anterior third, the longest two-thirds of head's 

 length. 



The anal origin is under the twentieth dorsal ray; its rays are nearly as long as those 

 of the dorsal. The pectoral has its penultimate ray produced, extending to the thirteenth 

 I'ay of the anal; it is nearly twice as long as the head. Ventrals originating in advance 

 of the vertical through the pectorals, and each a bitid filament. Distance of the ventral 

 origin from tip of snout (20 millimeters) equaling length of ventral and about three-fourths 

 as long as the head. Distance of origin of ventral from vent (42 millimeters) considerably 

 greater than length of head. Distance from tip of ventral to vent equal to half the length 

 of the head. 



Number of scales in transverse series from vent to dorsal about 2'S; from the upper 

 angle of the gill-opening t<> the vertical through origin of anal, 32. 



Color, brownish yellow*. Ilead and abdomen blackish. 



Radial formula: D. 93; A. 73; P. 17; V. 2. 



The type (37342, U. S. N. M.) was taken at Albatross station 2380, K. lat. 28° 02' 30", 

 W. Ion. S70 43' 45", 1,430 fathoms. It is 183 millimeters long to caudal base, 21.5 with 

 caudal. Another young siiecimen 70 millimeters long was taken at Blake station, xcv, off 

 Dominica, 330 fathoms. 



POROGADUS, Goode and Bean. 



Porogadus, Goode and Bean, Proc. U. S. Nat. Mus., 1885, viir, 602. — Gunther, Challenger Rei)ort, xxn, 

 1887, III. 



Body brotulif orm, much compressed. Head with numerous spines on iuterorbital space, 

 two pairs on the shoulders, one at angle of operculum, and a double series on angle of pre- 

 operculum. Head with nun)erous mucous pores, as in Bassozctus. Mouth large. Snout 

 moderate, not projecting nuich beyond upper jaw. 



Jaws nearly equal in front. Teeth in villiform bauds in jaws and on vomer and pala- 

 tines. Barbel none. 



Gill-openings wide, membranes narrowly united, not attached to the isthmus. Gills 4. 

 Gill-laminai short. Gill- rakers moderate, numerous. Pseudobranchiffi absent. Caudal fin 

 of few rays, on a very narrow base, not prolonged, scarcely difl'erentiated from the vertical 

 fins. D orsal and anal fins well developed. Pectorals simple, moderate. Each ventral a 

 single bifid ray, close to the humeral symphysis. Branchiostegals 8. Scales small. Lateral 

 line apparently triple, or replaced by three series of pores, one close to ventral outline, 

 one median, and another along base of dorsal. 



Type, Porogadus miles, Goode and Bean. 



POROGADUS MILES, Goode and Bean. (Figure 292.) 



Porogadus miles, Goode and Bean, Proc. U. S. Nat. Mns., 1885, viii, 602.— Gunther, Challenger Report, 

 xxn, 1887, 113. 



Body much compressed, elongate, tapering to a very slender tail, its height (15 milli- 

 meters) nearly 10 times in total length. 



Head long, moderately compressed, .subconieal; the profile gradually ascending in 

 nearly a straight line from the tip of the vsnout to the origin of the dorsal. Its length (23 

 millimeters) (5i times in that of body. Iuterorbital space slightly convex, spiny, its width 

 (15 millimeters) 43- times in length of head, and slightly greater than diameter of eye. 



Eye oval, its greatest diameter (4 millimeters) 5^ times in length of head. Opercles 

 and head generally covered with numerous and strong spines, as described in the generic 

 diagnosis. 



Mou th very large and wide. The maxilla extending far behind the eye and much ex-
