and is movable to some extent on the end of the rod while the process 

 is most likely subject to lively contortion. 



Both dorsal and anal are hardly visible externally ; only the ends of 

 some of the rays and of those of the caudal protrude beyond the skin, 

 Plate XIII., fig. 1 ; but on removal of the skin, Plate XIV., fig. 1-2, 

 this is seen to be a degenerate condition, the dorsal and anal being well 

 developed, each having six (excepting the illicium) simple rays, the first 

 of them unsegmented, Plate XV., fig. 3. Dorsal origin half way from 

 the orbit to the end of the caudal ; anal origin below the second ray of 

 the dorsal, hindmost rays of both anal and dorsal reaching the bases of the 

 caudal rays ; depth of caudal three-fourths of its length, fin blunt pointed ; 

 pectorals small, short, broad, one and one-half times as long as wide, some- 

 what pointed, rays inserted toward the upper side of the carpals which 

 latter are as long as the fin and widen backward, Plate XIV., fig. 2. 

 No traces of the ventrals. 



Stomach large, without pyloric ca'-ca ; intestine short. The two sides 

 of the viscera are figured on Plate XV., figs. 5-6. No air bladder. Speci- 

 men desci'ibed two and seven-eighths inches in length. 



Deep black over the entire surface and on the linings of the body 

 cavity. The only departui-e from an intense black is made in the esca 

 of the illicium (Plate XIII., Fig. 5-7) which is white (probably luminous 

 in life) in the upper portion and in the peculiar figure on the edge of 

 the lower half.

High, thick, and massive at the nape and shoulders, tapering to slender

 caudal ; width in the temporal region nearly three fourths of the depth, 

 narrower toward the throat; depth of caudal pedicel at its narrowest less 

 than one fifth of the depth of the body. Length of head less than half of 

 the total, greatest depth one and one third times the width ; forehead and
