458 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 48. 



Head short, blunt, the profile very steep, slightly more so than in 

 females of E. grandisquama; upper eye slightly posterior, its anterior 

 border being on about the same vertical as the anterior edge of the 

 pupil of the lower eye, diameter of upper eye 0.09; interorbital mod- 

 erately wide, as usual in females of other species of this genus, inter- 

 orbital width 0.06; nostrils as in E. grandisquama, closely approxi- 

 mated, the anterior with a short slender flap, the posterior very 

 slightly tubular, slightly in advance of anterior margin of lower 

 orbit; snout from upper orbit 0.12; maxillary of eyed side 0.10, reach- 

 ing, as in E. grandisquama, a vertical slightly beyond the anterior 

 margin of lower orbit; teeth strong and recurved, in a series similar 

 on both sides of jaws, in addition to which a series of shorter, stouter 

 teeth are developed outside of the main series; anterior end of pre- 

 maxillaries with a few enlarged teeth, which are outside the mandib- 

 ular symphysis when the mouth is closed, thus differing from E. 

 Icobensis and E. grandisquama, but resembling the species of Arno- 

 glossus; vomer and palatines toothless; gill-rakers short and slender, 

 2 + 14 (no other species of Japanese Psettinae has gill-rakers on the 

 upper limb of the arch; no other has more than 8 on the lower limb) ; 

 a small tubercle present on the eyed side near tip of snout; lower mar- 

 gin of upper orbit and upper margin of lower orbit raised near center. 



Form of body ovate, as in E. grandisquama; depth of caudal 

 peduncle 0.11; width of body 6.5 in depth. 



Scales ciliated or weakly ctenoid on eyed side, cycloid on blind 

 side, large and caducous, as in E. grandisquama; only the tip of 

 snout and jaws naked. Lateral line arched on eyed side, absent on 

 blind side. % 



Origin of dorsal slightly on blind side, on a horizontal from upper 

 margin of lower orbit; no anal spine, pubic spine sharp and triangu- 

 lar, as in related forms; caudal subsessile, slightly pointe.d, its middle 

 rays as long as head; pectoral of eyed side with 10 rays, its length 

 0.23; pectoral of blind side with 8 rays, its length 0.14; ventrals each 

 of 6 rays, the base of right ventral about 0.3 base of left ventral. 



Color as in E. grandisquama, with a similar pair of dark spots on 

 caudal. " Light yellow spots bordered with darker in front of inters 

 orbital area." (Dr. C. H. Gilbert's color notes.)
