448 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



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

 line. The third and fourth rays of the tin upon the eyed side elongated. Its length (38 

 millimeters) is contained 2h 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 rid.ue at a distance from the 

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

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

 has G rays; its length is contained 2{j times in length of the head. 



Radial formula: D. 91 ; A. 73; 1'. 10/6; V. 5. L. hit. 48; L. fcransv. 14 1<>.

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

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

 same vessel from station xxvi, oft Ste. Lucie, in 110 fathoms; and from stations xix, XXVIII 

 and xxix, off Barbados, in 310, 863, and 9.">5 fathoms respectively.

 Auctorum). 



Body sinistral; general form that of an ellipse, the caudal extremity being considerably 

 produced. Its height is contained 2j times in its length,2| times in itslength 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 hiterorbital space of the eyed side are smaller than upon the body. The scales on 

 the body arc 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 witli a very gentle curve, to the upper 

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

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



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

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

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

 of the head. Mouth rather large, the upper edge somevt hat 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 

 2J times in the length of the head. Teeth moderate, equally developed on both sides, in two 

 rows in the upper 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 upper jaw. 



The eyes are large, prominent, and far apart. Their longitudinal diameter equals the 

 length 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 advauceof the upper, the vertical from the anterior margin of the upper orbit cutting 

 the lower orbit at a point about two-thirds the distance from its anterior to its posterior 

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

 ing about one-half its longitudinal diameter. The iuterorbital space is rlattish and uneven,
