DISCUSSION OF SPECIES AXD THEIR DISTRIBUTION. 405 



length equals half that of the head without the snout. The niaiulible extends behind the 

 vertical through the posterior margin of the orbit; its length is contained .3 times in 

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

 villiform bands in intermaxillary and mandible; the mandibulary series uuiserial in about 

 the second half of its length. 



The first ray of the dorsal is Aery short; the second comi)ressed 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. This fin is seated upon a 

 hunqilike elevation of the back, and its base is as long as the snout. The second doisal 

 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 snout. The vent is located not far behind the 

 vertical from the end of the first dorsal. 



Scales 22 to 24 in 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 composed of small spines and rather large. Gill membrane very 

 deeply cleft and attached to the isthmus. Gill-rakers short and stout, about 11 below 

 the angle on the first arch. 



Radial formula: 1). li, 8-f 100; A. 117; Y. 10. 



The Blake secured specimens from station cccviii, in 41° 24' 45" N. lat., 65° 35' 30" W. 

 Ion., at a depth of 1,242 fiithoms; from station CCCXLI, in 39^ 38' 20" N. lat., 70o 50' W. Ion., 

 at a depth of 1,241 fathoms ; from station cccxxxviii, in 3S^ 18' 40" N. lat., 73° IS' 10" W. 

 Ion., at a depth of 922 fathoms; and from station cccxLii, in 39^ 43' N. lat., 70° 55' 25" W. 

 Ion., at a depth of 1,002 fathoms. Most of these had their tails broken off, and all of 

 them were completely denuded of scales; a natural consequence of their passage in the nets 

 from the ocean dei^ths. By a happy chance two scales were found attached to the base of 

 the dorsal fin of one of the larger individuals, thus enabling us to determine the general 

 character of the covering of the body.
