80 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



margin and the root of the caudal. Pectoi'als very long, reaching to above middle of anal. 

 Ventral readies almost to anal origin. Caudal moderate, well forlied. Mediohiterals, 3; 

 ])0!sterolaterals, 2. Precaudals, 3-4, the last at the end of the lateral line? Posterolaterals 

 in advance of the first dorsal, forming a gently curved series continuous with anterior half 

 of broken suijeranal series. 



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



A single specimen (No. 43777, U. S. N. M.), 52 millimeters in length, was .obtained by 

 the Gloucester fleet, it being No. 1!)9 of the Gloucester series. 



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

 Museum and the Fishes of the Chrdlciujer, monumental works, which are the foundations of 

 ichthyological work in the last half of the nineteenth century. 



LAMPANYCTUS WARMINGII, (Lutkkn), Goode and Bean. 



Scopelua (Notoseopehis) Wannhigii, Li'TKEN, Spolia Atlantica, II, 1892, 259, fig. 19. 



Asijecies closely dUiedto Lam2)anyctus Oiintheri, having long pectorals, and precaudals 

 3-4-1, the last at end of lateral line. Superanals, 7+5. Kadial forinnla: D. 12; A. 13. 



This species is distinguished from L. Giintheii by having one more precaudal plioto- 

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

 origin of the anal, while in L. Gilntheri it extends far behind the end of the pectoral and 

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

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



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



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

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

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

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

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

 equal to length of jiostorbital part of head, and about e(|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 larger 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 nearlycontinuous line with lowest prepectoral and mediolaterals. Num- 

 ber of superanals 7-8. The pearly mirror upon 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 formula: D. II, 12; A. II, 16, V. 8, P. 15, 16. Scales 5, 38, 5. 



Gill rakers, 6 above and 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, 7^ inches in length, 

 was taken by the Albatross at station 2201, in 3!»o 39' 45" N. lat., 71° 35' 15" W. Ion., at a 

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