 but ill-defined, except where forming a narrow streak towards the tail.

This species seems to be affined to H. Reynaldi of Valenciennes. 



H. brachynotopterus, Bleeker : Esox angulatus, B. H. (MS. on draw- 

 ing). Upper jaw very short, triangular, broader than long, almost flat 

 but with distinct angulate ridge. Eyes three-fifths of the vertical diame- 

 ter of the head. Tail furcate. Ventrals placed midway ou the body, far 

 anterior to the anus. In a specimen 7 in. long, the lower jaw exceeds the 

 upper by l^ in., and the upper jaw from cleffc of mouth measures ■£-$ in. I 

 have not seen it larger. A narrowish well defined silvery stripe extends 

 from the base of the pectorals to the middle of the caudal. The dorsal fin 

 contains 11 to 13 rays in perfect specimens. 



D. 11 to 13.— A. 15.-P. 7.— V. 6.— C. 14. 



H. striga, nobis, n. s. With upper jaw subtriangular, rounded in 

 front, a little longer than broad, fiat, with very indistinct trace of angulate 

 ridge; the lower jaw much longer than in the two preceding species. 

 Eyes three-fifths of the vertical diameter of the head. Tail rounded. 

 Ventrals small, placed near but not reaching to the anus. In a specimen 

 8^ in. long, the lower jaw exceeds the upper by 2£ in., and the upper jaw 

 from cleft of mouth measures 5 in. Lateral silvery stripe narrow and 

 little perceptible, excepting towards the tail, where broader and distinct. 

 A medial dusky line along both mandibles and middle of the fore-part 

 of the back. Operculum brilliant silvery. 



D. 12 or 13.— A. 8 or 9.— P. 9 or 10.— V. 6.— C. 14. 



H. plumatus, nobis, n. s. General aspect of preceding species, but 

 the eye less than half of the diameter of the head : the lateral scales of 

 the body also much larger; and the upper jaw tapering to an obtuse 

 point, and distinctly angulated. Each nostril covered by a remarkable 

 plume of filaments. Tail furcate. Ventrals placed near the anus, but 

 not reaching to it. In a specimen 11 in. long, the lower jaw exceeds the 

 upper by 2\ in., and the upper from cleft of mouth measures | in. A well 

 defined silvery stripe from base of pectorals, becoming rather broad 

 towards the tail. 



D. 15.— A. 13.— P. 9.-V. 6.— C. 15.
