flap of tbe operculum ; its leugtli (13""") about equal to two-tliirds that 

 of head. 



Ventral, a bifid ray, inserted slightly iu advance of the base of the 

 pectoral and not far from humeral symphysis. It reaches nearly to the 

 vent. Its length (15"^™) nearly equal to height of body. 



Distance from origin of ventral to vent slightly greater than height 

 of body. 



Color light yellow, with silvery reflectious, with clouding of brown 

 above lateral line and numerous black chromatophores. 



A series of irregular brown blotches above the lateral line, with two 

 much darker, extending uj) on the dorsal fin, the largest about midway 

 from the head to the tail. 



Porogadus, new genus, Brotulidce. 



Body brotuliform, much compressed. Head with numerous spines 

 on interorbital space, two pairs on the shoulders, one at angle of oper- 

 culum, and a double series on a ogle of preoperculum. Head with nu- 

 merous mucous i^ores, as in Bathyonus. Mouth large. Snout moderate, 

 not projecting much beyond upper jaw. 



Jaws nearly equal in front. Teeth iu villiform bands in jaws and on 

 vomer and palatines. Barbel none. 



Gill-openings wide, membranes narrowly united, not attached to the 

 isthmus. Gills 4. Gill-laminae short. Gill-rakers moderate, numerous. 

 Pseudobranchiae absent. Caudal fin of few rays, on a very narrow 

 base, not prolonged, scarcely differentiated from the vertical fins. Dor- 

 sal and anal flus well developed. Pectorals simple, moderate. Each 

 ventral a single bifid ray, close to the humeral symphysis. Brauchios- 

 tegals 8. Scales small. Lateral line apparently developed only on an- 

 terior part of body, close to dorsal fin. Three series of pores, one close 

 to ventral outline, one mediau, and another along base of dorsal. 



Porogadus miles, n. s. 



The type (No. 35625, U. S. N. M.) is 153 millimeters in length ; it is 

 from Albatross station 2230, north latitude 38° 27', west longitude 

 73° 02', at a depth of 1,168 fathoms. 



Description: Body much compressed, elongate, tapering to a very 

 slender tail, its height (15'"'") nearly 10 times in total length. 



Head long, moderately compressed, subconical; the profile gradually 

 ascending in nearly a straight line from the tip of the snout to the 

 origin of the dorsal. Its length (23°^™) 6i times iu that of body. Inter- 

 orbital space slightly convex, spiny, its width (5™'") 4f times in length 

 of head, and slightly greater than diameter of eye. 



Eye oval, its greatest diameter (4'"™) 5f times in length of head. 

 Opercles and head generally covered with numerous and strong spines, 

 as described in the generic diagnosis. 



Mouth very large and wide. The maxilla extending far behind the 

 eye and much expanded at its tip; its length (13'""^) more than half
