DISCUSSION' OP SPECIES AND THEIR DISTRIHUTION. 405 



length equals half that of the head witliout the snout. The iiiaiidihle extends behind the 

 vertical through the posterior margin of tlie orbit; its lengtli is contained 3 times iu 

 the distance from the tip of the snout to the origin of ihe lirst dorsal. The teeth are in 

 villiform bands iu intermaxillary and mandible; the mandibulary series niiiserial in about 

 the second half of its length. 



The first ray of the dorsal is very short; tlie second c<mipressed anteriorly and ser- 

 rated, with slender teeth closely appressed and bent upwards. Its length is equal to the 

 length of the head and is greater than the height of the body. Tliis (in is seated upon a 

 huniplike elevation of the back, and its base is as long as the snout. The second dorsal 

 begins over the tenth or twelfth anal ray, and at a distance from the end of the first dorsal 

 equal to the length of the head without the snont. The vent is located not far behind the 

 vertical from the end of the first dorsal. 



Scales 22 to 24 iu a transverse series (the position of the lateral line can not be deter- 

 mined, but there appear to be 4 above it); the scales are oval, membranaceous, showing 

 several parallel ridges comj)osed of small spines and ratlicr large. Gill luembrane very 

 deeply cleft and attached to tlie isthums. Gill-rakers short and stout, about 11 below 

 the angle on the first arch. 



Radial fornutla: I), ii, 8+100; A. 117; Y. 10. 



The Blale secured specimens from station CCCVIII, in 41 "^ 24' 4.j" N. lat., 05° 35' 30" W. 

 Ion., at a depth of 1,242 fathoms; from station cccxxi, in 39° 38' 20" N. hit., 70^ 50' W. Ion., 

 at a depth of 1,241 fathoms; from station cccxxxviii, in 38^ 18' 40" N. hit., 73^ IS' 10" W. 

 Ion., at a depth of 022 fathoms; and from station CCCXLii, in 39^ 43' N. lat., 70^ 55' 25" W. 

 Ion., at a depth of 1,002 fathoms. ]\Iost of these had their tails broken oil, and all of 

 them were completely denuded of scales ; a natural consequence of their jiassage iu the nets 

 from tlie ocean depths. l!v a hajipy chance two scales were found attached to the base of 

 the dorsal flu of one of the larger iiulividuals, thus enabling us to determine the general 

 character of the covering of the body.
