404 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



times as long as diaineter of eye. Bye ciieular, in larger individual its diameter less than 

 width ofinterorbital space, 3| times in length of head, yuout short, obtuse, scarcely over- 

 hanging the mouth, its length (7 millimeters) 4i times in that of head; in the larger indi- 

 vidual it is 4;\ times in length of head. 



Nostrils somewhat above level of middle of eye, the anterior one nearly upon the dorsal 

 outline. 



Teeth in upper jaw in two series, the outer series somewhat enlarged; in lower jaw in 

 a single series. 



The end of the maxilla reaches to the vertical through the hind margin of pupil in the 

 large specimen, to that through the front margin of the same in the type. Length of 

 upper jaw, including maxilla (11 millimeters), about 3 times in length of head. Length 

 of mandible (13 millimeters) equal to one-half the height of the body. Barbel (4 millime- 

 ters) 2.J times in diameter of eye; in the large specimen it is half as long as the eye. 



Gillrakers rudimentary: the attachment of the membrane to the first arch is very 

 extensive. PseudobranchiiB absent. 



First dorsal comparatively low, composed of 2 spiiu^s, the first rudimentary, the second 

 elongate, smooth, and with 8-9 rays. Its insertion is immediately over that of the pectoral; 

 its distance from the snout (36 millimeters) ecpials IJ times the length of the head; its length 

 of base (7 millimeters) equal to length of snout. Its longest spine, when laid backward, 

 reaches beyond origin of second dorsal, its length (15 millimeters) one half to tw'o thirds 

 that of the head. 



Second dorsal very low; its distance from first dorsal equal to one-third length of head; 

 in the type about one-fourth. 



Anal much higher than second dorsal, yet very low, its longest ray ecjual in length to 

 diameter of eye; its distance from snout (51 millimeters) 45 times in total length, its origin 

 being nearly under that of the second dorsal. 



Pectoral inserted under origin of first dorsal, its length about one-half tliat of head. 



Ventral inserted behind the vertical from the end of the base of the hrst dorsal in the 

 type. In the mutilated larger specimen it appears to be under the posterior ray of the first 

 dorsal. The ventral extends to the origin of the anal, its length (10 millimeters) equaling 

 diameter of eye ; in large specimen 1^ diameter of eye. Vent about midway between origin 

 of ventrals and anal. 



Eadial formula: D. 11, 8-9; A. 120; V. 7; P. 13. 



In a distance equal to length of head 32 rays were counted in the dorsal flu; in the 

 anal fin 22. 



Color brown, abdomen and lower part of head in young blackish. 



The type of this species, 37335, is an individual 238 millimeters long, taken at Albatross 

 station 2394, with a large specimen (about 350 millimeters) badly mutilated, from Blake 

 station Lxxiii, off Martinique, 472 fathoms, as a collateral type. (See page 409, below.)

The snout is acute, projecting beyond the mouth, its tip at a distance from the mouth 

 equal to or greater than the diameter of the eye. The bones of the head are very soft aud 

 flexible, and its surface is very irregular, there being a very ])rominent subocular ridge, a 

 prominent ridge extending Irom the tip of the snout to the middle of the interorbital space, 

 a7i(l a curved ridge extending from the upper anterior margin of the orbit over the cavity 

 containing the nostrils to a prominent j'oint at the side of and slightly i>osterior to the tip 

 of the snout. The barbel is two-thirds as long as the eye. The eye is contained in the head 

 4 times, and the length of the head in the total length times. 



The iuteroi'liital space is almost twice the diameter of the eye, and is equal to the length 

 of the upper jaw. The i)reoperculum is crenulate. 



The upper jaw extends to the vertical through the posterior margin of the pupil; its
