212 DEEP SEA FISHES. 



longer tlian the distance across the interorbital space, little longer than the 

 distance from the end of the snout to the maxillaries, one third of the 

 length of the head. Mouth small, cleft to a vertical from the middle of 

 the eye. Teeth very small, subequal, in villiform bands. Baibel small, 

 slender, one half as long as the eye. Median rostral ridge hardly rising 

 higher than the narial ridges, ending at a line joining the front edges of 

 the orbits. Upper edges of the orbits scarcely rising above the forehead. 

 Origin of the first dorsal above the axil of the pectoral ; second ray serrate, 

 with a filament, nearly three fourths as long as the head ; base descending 

 rapidly backward. Second dorsal separated from first by less than two 

 lengths of the base of the latter, low, feebly developed, widest near mid- 

 length. Ventrals small, more than half as long as the head, first ray 

 prolonged in a filament, origin a little forward of the bases of the pectorals. 

 Pectorals larger than the ventrals, three fourths as long as the head. Vent 

 di-itant from the anal, near the bases of the ventrals. Anal origin farther 

 backward than the base of the first dorsal hy about the width of two scales. 

 Preopercular ridge bent forward in the middle, or rounded backward in 

 the lower portion. Occipital crest prominent. Scales rather harsh, with 

 longitudinal series of small spines, up to eight or more rows on each scale. 

 Spinules on the second spine of the first dorsal less numerous on young 

 specimens, absent to some extent near the base. Frequently on very 

 young there are two or three spinules in a group near the base of the 

 spine separated from the upper ones. 



Black on the abdominal chamber; blackish to reddish brown over tlie 

 muscular jiortions, shading to lighter over the mucous cavities on the head. 



Distinguished from 31. convergens by a shorter broader snout and by the 

 fin rays ; on that species the median rostral angle is sharper.

 Body compressed, slender and whip-like posteriorly, depth two thir- 

 teenths, head one fifth, and snout to anal one third of the total length.
