no. 2082. FLOUNDERS AND SOLES FROM JAPAN— HUBBS. 453 



anal ridge; origin of dorsal slightly on blind side, near anterior 

 margin of upper orbit; dorsal and anal deflected to the blind side 

 of the caudal peduncle, both fins high to their posterior ends; anal 

 spine present, but weak; scales very large, weakly ctenoid; arch in 

 lateral line long and angulated behind; upper orbit larger than the 

 lower and anterior to it; gill-rakers slender; anus on eyed side in both 

 genera, a character apparently peculiar to them, as in all other 

 flounders examined the anus is on the preanal ridge or on the blind 

 side. 



Citharoides differs from Citharus in dentition, the vomer being 

 toothless; and in the more regular jaw, the premaxillaries being much 

 less prominent, the mandible anteriorly being flat, instead of strongly 

 arched downward. 



Type of the genus. — Citharoides macrolepidotus, new species. 



CITHAROIDES MACROLEPIDOTUS, new species. 

 Plate 25, fig. 1. 



Type-specimen. — Cat. No. 75670, U.S.N.M. A male 59 mm. long, 

 from Albatross station 4874, in the eastern channel of the Korean 

 Strait; depth, 66 fathoms; collected August 2, 1906. 



Length of head, 0.29 of total length to base of caudal; depth, 0.37; 

 dorsal, 66 ; anal, 45 ; 40 series of scales along the lateral line. 



Head obtusely pointed, the profile only slightly elevated at a point 

 above the anterior part of the upper eye ; upper orbit, as in Citharus 

 linguatula, larger and considerably anterior to the lower, the anterior 

 margin of the lower eye only slightly anterior to the vertical of the 

 anterior border of the upper pupil; diameter of each eye 0.08; eyes 

 separated by an exceedingly narrow ungrooved ridge, which is not 

 extended anteriorly nor posteriorly, its length about 0.05; nostrils 

 as in Citharus linguatula, the anterior nostril with a short flap, the 

 posterior nostril wide, its anterior wall within with a flap; snout 

 somewhat rounded, its length 0.06; mouth large, symmetrical, and 

 moderately oblique, the mandible projecting; length of maxillaries, 

 0.14, extended to below posterior margin of lower pupil; teeth sym- 

 metrically placed on jaws, those of upper jaw uniserial, with several 

 enlarged teeth irregularly placed, those of lower jaw uniserial pos- 

 teriorly, becoming biserial and finally forming a narrow band at 

 symphysis; vomer and palatines toothless; a bony tubercle present 

 at anterior end of arch in lateral line; 9 slender gill-rakers on lower 

 limb of arch, their posterior edges serrate, 3 tubercles on upper limb, 

 the longest gill-raker (the third from the angle of arch) about 0.03. 



Body elliptical, the greatest width about 6 in the greatest depth; 

 depth of caudal peduncle 0.12; caudal peduncle angulated above and 

 below in cross section. 



Scales weakly ctenoid and deciduous on the eyed side, cycloid on 

 the blind side; snout and jaws naked; fins, except caudal at base,
