To tills genus apparently belong, in addition to the type species, B. ilUlleri { = B. gla- 

 ciaits,Eeinhardt, as identified by Liitken),the two species described by Liitken now under 

 the names Scopelufi arcticns and Scopchis CoUetti. The species described by us under the 

 name Bcnthosema (iuntherl 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, witli upper profile descending in a very strong 

 curve. Cleft of mouth obli(iue; maxillary reaching to angle of 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 veiy small, its length equal to 

 diameter of 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 ; xiosterolateial, one, over break in series 

 of anals. Superanals 6-7 -f 8-9. Eadial formula: D. 12-14; A. lG-18; V. S, L. lat. 30-40. 



This species, until recently known only from the coast 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 obtaiiu^d by the Norwegian North Atlantic Expedi- 

 tion in a dredge 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 far south as the coast of South 

 Carolina. The specimens are usually in a veiy soft and battered condition, indicating that 

 they have been obtained at a considerable deiith; and (Jollett found in the stomach of one of 

 those examined by him an ostracod (Cottca;cia&»reaM.9), which has never been found nearer 

 the surface than at a depth of 300 fathoms. Giinther and Collett believe it to be truly 

 bathybial, and the testimony of the Fish Commission explorers tends in the same direction 

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



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

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

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

 Ion., at a depth of .30.5 fathoms; one specimen from station occix, in 40° H' 40" N. lat,, 

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

 39' 40" N. lat., 75° 14' 40" W. Ion., at a depth of 603 fethoms, and two specimens in bad 

 condition tiom station cccxxxii, in 35° A5' 30" N. lat., 74° 48' W. Ion., in 263 fathoms. 



Specimens W(>re received from the Flxh Hawk as follows: Three specimens (No. 288.51,
