Barriotta, Goode & Bean, Oceanic Ichthyology, 32, 1891, (raleijhana). 



Snout exceediugly elongate, Avith a cartilaginous midrib, and foliaceous 

 lateral expansions of the skin at its base. Two dorsal fins, the anterior 

 with an immense triangular spine, finely serrated upon its lateral edges. 

 Anal liu reduced to a cutaneous fold. Longitudinal axis of the tail nearly 

 the same as that of the trunk, very elongate, with filamentous tip, the 

 fin below much more extensive than that above. No cephalic organ. 

 Gill openings lateral, separated by a wide isthmus. Claspers small and 

 simple. (" Named in houor of Thomas Harriott, the most eminent philos- 

 opher and naturalist of his day in England, who was a member of 

 Kaleigh's Roanoke colony in Virginia in 1585, and who published the first 

 work in English on American natural history.")

Tail extended in a very long filament, much longer in the older indi- 

 viduals than in the young; not present in very young. First dorsal fin 

 separated from the second by an interval nearly equal to the diameter of 

 the eye in the older individuals, very much greater in the younger ones, 

 in which the cartilaginous portion is exceedingly narrow and high ; 

 Second dorsal fin long and low, its height about equal to diameter of the 

 eye, its length equal to that of head. Dorsal spine very strong; its 

 length in the older individuals equal to the distance from its own base 

 to the origin of the second dorsal ; in the young it is proportionately 

 much longer and stouter; a double row of strong spines in advance of 

 the second dorsal, and in the notch between the second dorsal and its 

 continuation upon the upper part of the tail ; a similar group of at least 

 6 strong sjiines upon the top of the head back of the interorbital space, 

 and surrounded by the curve of the forward extension of the lateral line. 

 Traces of these spines may be lelt beneath the skin in older individuals 

 of both sexes. Claspers in the young male examined, small and simple, 

 in length scarcely equal to f the long diameter of the eye. Pectoral 

 fins immense, wing-like, rounded in the young, subfalcate in the older 

 individuals ; inserted slightly in advance of the origin of the first dorsal, 

 and extending in the older forms beyond the root of the ventral. Ven- 

 trals also subfalcate ; similar in form and appearance to the pectoral, and 

 extending to a point at 3 the distance from the origin to the end of the 

 second dorsal ; in length little less than i the snout. In the young the 

 ventrals are placed somewhat farther back and reach to a point under 

 the origin of the third section of the dorsal fin. Tail prolonged in a 

 slender filament, and in the older individuals the cutaneous flap upon its 

 lower edge is 3 or 4 times as deep as that above, and extends beyond it 

 anteriorly and posteriorly. In the younger specimens the upper and 

 lower flaps are al)out equal in height, and the upper flap extends far in 

 advance of the insertion of the lower one. Lateral line extending in a 

 straight line from a point beneath the origin of the first dorsal approxi- 

 mately to the middle of the lower caudal lobe, which it follows along 

 its base for the remainder of its course; in advance of the dorsal fin it
