total length, the length of the head four times and a half. The 

 snout is subconical, somewhat longer than the eye, with the jaws 

 equal anteriorly. The width of the interorbital space is much less 

 than the vertical diameter of the eye. A long fringed tentacle at 

 the nostril, that above the orbit being rather shorter. Scales mi- 

 nute. The detached dorsal fin is situated on the nape of the neck, 

 above the operculum ; the last dorsal ray is fixed by a membrane to 

 the back of the tail, but is free from the caudal fin. Uniform yellow- 

 ish (in spirits).
