 nous dorsal very long, with thirty or more spines, continuous with the second; six finlets

A Gempylus with the veutrals reduced to a pair of very small spines. The height of the

 5£ times in the same distance. Body scaleless. Color uniform, the upper part of the dor- 

 sal fin black.

Pyloric caeca, 9-10. 



Giinther considers all known forms of this genus as belonging to a single species, includ- 

 ing G. coluber, C. & V., the Pacific form, which he has figured in his Fische der Siidsee, pi. 

 lxviii, fig. 15. It has been rarely obtained at the Canary Islands, in the Caribbean Sea, 

 and near the Society and Sandwich Islands. It is generally believed to be an inhabitant of 

 great depths.
