76 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



line considerably enlarged. Mediolaterals, 2, in subhorizontal line, continuous with the two 

 anterolaterals, (fjiyftos, the ocean depth: -',,"/, a constellation of stars.) 



To this genus apparently belong, in addition to the type species, B. Mulleri ( = B. gla- 

 cialis, Bernhardt, as identified by Liitken), the two species described by Liitken now under 

 the names Scopelus arcticus and Scopelus Golletti. The species described by us under the 

 name Benthosema Giintheri is now referred to our modified genus Lampanyctus.

Height of body about equal to length of head, and is contained 4 times in total length; 

 the depth of head about equal to its length. Eye large, its diameter more than one-third 

 length of head. Snout very short, obtuse, with upper profile descending in a very strong 

 curve. Cleft of mouth oblique; maxillary reachiugto angleof preoperculum and terminat- 

 ing in triangular dilation. Origin of dorsal a little nearer the tip of snout than root of 

 caudal, and inserted well behind root of ventral. Pectoral very small, its length equal to 

 diameterof eye. Ventral does not reach to the vent. Scales smooth, those of lateral line 

 larger. A luminous spot on the angle of the preoperculum. Mediolaterals, 2, in subhori- 

 zontal line continuously with the two anterolaterals ; posterolateral, one, over break inseries 

 of auals. Superanals 6-7+8-9. Radial formula: D. 12-14; A. 16-18; V. 8, L. hit. 30-40. 



This species, until recently known only from the roast of Greenland and the northern 

 shores of Norway, has been frequently taken since 1881 by the IT. S. Fish Commission off 

 the southern shores of New England, and also by the Blake at numerous stations mentioned 

 below. Collett believes it to have been obtained by the Norwegian North Atlantic Expedi- 

 tion in a (hedge which was worked at a depth of 1,110 fathoms. The depth of the west 

 Atlantic was from 300 to 600 fathoms, and it was found as tar south as the coast of South 

 Carolina. The specimens are usually in a very suit ami battered condition, indicating that 

 they have been obtained at a considerable depth; and ( 'ollett found in the stomach of one of 

 those examined by him an ostracod (Concosciaborealis), which has never been found nearer 

 the surface than at a depth of 300 fathoms, (i anther and Collett believe it to be truly 

 batbybial, and the testimony of the Fish Commission explorers tends iu the same direction 

 with regard to these as to the majority of the other species of the family. 



Specimens of this species were obtained by the Blake from the following localities: 

 One specimen from station ccom, in 41° 34' 30" N. hit., 65° 54' 30" W. Ion., at a depth of 

 306 fathoms; three specimens from station cccxxxrv, in 38° 20' 30" N. kit., 73° 26' 40"W. 

 Ion., at a depth of 395 fathoms; one specimen from station cccix, in 40° 11' 40" N. lat., 

 68° 22' W. Ion., at a depth of 304 fathoms; three specimens from station cccxxix, iu 34° 

 39' 40" N. hit., 75° 14' 40" W. Ion., at a depth of 603 fathoms, ami two specimens in bad 

 condition from station cccxxxn, in 35° 45' 30" N. lat., 74° 48' W. Ion., in 263 fathoms. 



Specimens were received from the Fish Hawk as follows: Three specimens (No. 28851, 

 IT. S. N. M.) from station 952, in 39° 55' N. lat,, 70° 28' W. Ion., at a depth of 396 fathoms; 

 two specimens (No. 28950, U. S. N. M.) from station 1029, in 39^ 57' X. lat, 69° 16' W. Ion., 

 at a depth of 458 fathoms, and three specimens (No. 28839, U. S. N. M.) from station 953, 

 in 39° 52' 30" N. lat., 70° 17' 30" W. Ion., at a depth of 724 fathoms. Also by the Albatross 

 at the following stations: Ten specimens (No. 32672, IT. S. N. M.) from station 2002, in 37° 

 20' 42" N. lat., 74° 17' 36" W. Ion., at a depth of 641 fathoms; four specimens (No. 35643, U.
