■laws subequal in length, sometimes the lower, sometimes the upper the longer; the upper 

 with a projecting fleshy tip; maxillary reaching to opposite gill openings, which arc rather 

 longer than the large eye. Head 3j in distance from snout to dorsal, 2j] in distance to anal. 

 8i| in length. Vomerine teeth uniserial. Eye broader than interorbital space, rathernearer 

 tip of snout than end of maxillary. Tail about twice as long as body. Pectoral .slender, 

 longer (ban snout. CTniform brown, rather darker below; the vertical fins darker behind, 

 light-edged anteriorly; inside of mouth blue-black; gill openings dark. 



This remarkable eel was first made known by the Madeiran ichthyologists, Lowe and 

 Johnson, by whom it was found at 74(1 fathoms and in intermediate depths. The Challenger 

 obtained it near the coast of Brazil, in 1,200 fathoms; off Japan, in 345 to 565 fathoms; and 

 about the Philippines, in 375 to 500 fathoms. Its presence iu the western Atlantic was first 

 detected by the Cape Ann fishermen, who in 1S79 began bringing them in from the offshore 

 banks, where they had been taken on trawl lines at 200 to 300 fathoms. In 1879 the Fish 

 Hawk took it often in 250 to 365 fathoms, and subsequently the Albatross and the Blake 

 brought it in from numerous stations at depths of 300 to 1,000 fathoms. The Travailleur 

 and Talisman took it in numerous localities; off Morocco, 912-2,210 meters; off the Canaries, 

 865-2,083 meters; off Soudan, 882-1,435 meters; on the Banc dArguin, 1,113-1,550; off 

 the Cape Verdes, 405-3,200; off the Azores, 1,257-2,235 meters.
