418 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



The pectorals originate immediately beliind the branchial opening, far below the lateral 

 line. The third and fourth rays of the fin upon the eyed side elongated. Its length (3S 

 millimeters) is contained 2A times in total length. This tin has 10 rays; that of the blind 

 side contains rays; its length (12 millimeters) is less than one-third that of its mate, and 

 is less than half the length of the head. 



The ventral on the eyed side originates upon the ventral ridge at a distance from the 

 snout (27 millimeters) equal to the length of the head; it contains 5 rays, the length of the 

 first (6i millimeters) contained 4 times in length of the head. The ventral of the blind side 

 has 6 rays; its length is contained 2?^ times in length of the head.

 Color, grayish brown above, white below. 



The type specimen, 92 millimeters long to base of caudal, was taken by the Blake from 

 station xxi, ofl' Guadaloupe, in 175 fathoms. Additional examples were obtained by the 

 same vessel from station xxvi, off Ste. Lucie, in 110 fathoms; aiul from stations xix, xxviii 

 and XXIX, oft' Barbados, in 310, 803, and 955 fathoms respectively.

Body sinistral ; general form that of an ellii)se, the caudal extremity being considerably 

 produced. Its height is contained 2^ times in its length, 2g times in its length to the end of 

 the caudal fin, and is 4 times the height of the tail at its lowest portion. Its height at the 

 ventrals is 3 times as great as at the tail. Its greatest width is equal to the diameter of the 

 upper orbit. 



The scales on the cheek of the blind side are arranged in 13 series; those upon the 

 nape and interorbital space of the eyed side are smaller than upon the body. The scales on 

 the body are large, thin, deciduous, and cycloid. There are 57 scales in the lateral line, 

 54 of which are tube-bearing. Lateral line straight, and over the axis of the body, save in 

 its anterior fourth, within which it slightly ascends with a very gentle curve, to the upper 

 angle of the gill opening. Above the lateral line are 13 scales; below, 22. The vertical 

 fins are scaly two-thirds of the distance to their tips. 



The head is short, its length being contained 3| times in the standard body length, 4J 

 times in the total length, and 1§ times in the greatest height of body. The snout is short ; 

 its length, slightly less than the diameter of tlie lower eye, is contained 5 times in the length 

 of the head. Mouth rather large, the upper edge somewhat curved, its cleft very oblique, 

 the maxillary extending to below the middle of the lower eye. The lower jaw extends to the 

 vertical from the anterior margin of the upper eye. Length of the upper jaw equals one- 

 third the distance from the snout to the insertion of the anal. The lower jaw equals the 

 distance from the tip of the snout to the posterior margin of the lower eye and is contained 

 2^ times in the length of the head. Teeth moderate, e(iually developed on both sides, in two 

 rows in the upi)er jaw, those of the outer row upon the blind side of the upper jaw and the 

 anterior portion of the eyed side considerably larger than those in the inner row. The teeth 

 of the lower jaw uniserial, almost as large as in the outer row of the u]>per jaw. 



The eyes are large, lu'ominent, and far apart. Their longitudinal diameter equals the 

 leiiji'th of the snout, and is contained 5 times in the length of the head. Their vertical 

 diameter is about three-fourths as great as their longitudinal diameter. The lower eye is 

 far in advance of the upper, the vertical from the anterior margin of the upper orbit cutting 

 the lower orbit at a ])oint about two thirds the distance from its anterior to its posterior 

 margin. The upper eye is close to the dorsal jirofile, separated from it by a distance equal- 

 ing about one-half its longitudinal diameter. The interorbital space is flatfish and uneven,
