LAEOPS KITAHARAE (Smith and Pope). 

 Lambdopsetta kitaharae Smith and Pope, Proc. U. S. Nat. Mus., vol 31, 1906, p. 496. 



This species is referable to the genus Laeops Giinther. The teeth 

 of the jaws are in narrow bands, developed wholly on the blind side. 

 No specimens were obtained by the Albatross. 



LAEOPS LANCEOLATA Franz. 



Laeops lanceolata Franz, Abh. bayer. Akad., 1910, p. 62, pi. 8, fig. 60. Fukuura; 

 Dzushi. 



L. lanceolata seems to differ from L. Tcitahirae in having more fin 

 rays (dorsal, 109 to 115; anal, 88 to 95, rather than dorsal, 103; 

 anal, 76); and in the smaller scales (120 rather than 100). Eye, 2.5, 

 instead of 3J. 



No specimens were obtained by the Albatross. 



LAEOPS VAPJEGATA Franz.

 Dzushi. 



This may be a larval form. Franz states that he did not exam- 

 ine its dentition. Its generic identification is therefore doubtful. 

 Its anterior dorsal rays are produced in front; dorsal, 110; anal, 90; 

 scales, 110; eye, 6.5. 



No specimens were obtained by the Albatross. 



LAEOPTICHTHYS, new genus. 



Body elongate-ovate, strongly compressed; eyes and color sinis- 

 tral; mouth small, the jaws of the blind side strongly curved, the 

 teeth in a single even series, confined entirely to the blind side of 

 both jaws; interorbital a narrow ridge; ventrals very unsymmet- 

 rical, the left with a very broad base; origin of dorsal in advance of 

 upper eye; rays of dorsal and anal numerous; no anal spine; scales 

 very small, cycloid, lateral line with a high angular arch; gill-rakers 

 rudimentary; anus nearly on pre anal ridge. 



Laeoptichthys differs from Laeops Gunther 1 in having the teeth in a 

 single even row, rather than in narrow bands. 



Type of the genus. — LaeopticMhys fragilis, new species. 



LAEOPTICHTHYS FRAGILIS, new species.
