80 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



margin iiiid the root of the caudal. Pectorals very long, reaching to above middle of anal. 

 Ventral readies almost to anal origin. Caudal moderate, well forked. Mediolaterals, 3; 

 |)osterolaterals, 2. Trecandals, 3-4, the last at the end of the lateral line. Posterolaterals 

 in advance of the first dt>rsal, forming a gently curved series continuous with anterior half 

 of broken suporanal series. 



Radial formula: U. 13; A. 13. Scales, 36. 



A single specimen (Xo. 43777, U. S. N. M.), 52 millimeters in length, was obtained by 

 the Gloucester fleet, it being No. 111!) of the Gloucester series. 



The species is dedicated to the author of the Catalogue of the Fishes of the British 

 }fiiKeiim and the Fishes of the Challeiujer, monumental works, which are the foundations of 

 ichthyological work in the last half of the nineteenth century. 



LAMPANYCTUS WAKMINGII, (Lutkkn), Goode aud Bean. 



ScopelM {XotoacopetKs) WarmiHgii, Lutkkn, Spolia Atlautica, ii, 1892, 259, fig. 19. 



A species closely alliedto Lampanyctws Gttw<7ieH, having long pectorals, and precaudals 

 3+1, the last at end of lateral line. Snperanals, 7 + 5. Radial formnla: D. 12; A. 13. 



This species is distinguished from L. Giintheri by having one more precaudal photo- 

 phores in the first group aud by having a shorter pectoral, which does not reach to the 

 origin of the anal, whiles in L. Giintheri it extends far behind the eud of the pectoral and 

 nearly to the middle of the base of the anal. The posterolaterals, one or two in luimber, 

 are continuous in the gently curved series of the anterior half of the broken superaual series. 



LAMPANYCTUS GEMMIFER, Goode and Bean, n. s. (Figure 88). 



Height of body is contained 5J times in total length ; length of head 3| times. Least 

 depth of tail two-thirds height of body. Eye large, nearly one-fourth length of head. Dis- 

 tance between posterior margin of orbit and preopercular edge eipmls diameter of eye. 

 Snoutobtuse, very short, its length less than half diameter ol eye. Maxillary scarcely dilated 

 behind. Origin of dorsal midway between tip of snout and dorsal mirror. Base of dorsal 

 ecjual to length of jjostorbital part of head, and about ec^ual to longest dorsal ray. Ventral 

 origin slightly in advance of dorsal origin. Pectoral reaches slightly beyond origin of anal. 

 Scales smooth, those of the lateral line scarcely laiger than others. Mediolateral photo- 

 phores, 2; posterolaterals, 2, the latter one above the other, or nearly so. Precaudals, 4-5 

 in nearly horizontal though curved row, the last far below the end of the lateral line. 

 Anterolaterals, 3, in nearly continuous line with lowest prepectoral and mediolaterals. Num- 

 ber of snperanals 7-8. The pearly mirror upou the upper edge of the caudal peduncle as 

 long as the eye, and much longer than the one extending from the end of the anal to the 

 root of the caudal; slender and narrow, two-thirds as long as the head. 



Eadial fornuila: D. II, 12; A. II, 10, V. 8, P. 15, IG. Scales 5, 38, 5. 



Gill rakers, 6 above aud 12 below angle of first arch; longest two-thirds as long as eye. 



A single individual (No. 35604, U. S. N. M.), the type of the species, 7i inches in length, 

 was taken by the Albatross at station 2201, in 300 39' 45" N. lat., 71° 35' 15" W. Ion., at a 

 depth of 538 fathoms. Bcopelus Bonapartii of Cocco and Bonaparte is nearly allied.
