7. Liza parva Oshima, sp. nov. (Plate XI, fig. 2.) 

 Hime-menada (Japan); Shoahii (Formosa). 



Head 3.73 in length; depth 3.35; D. IV-i, 8; A. Ill, 9; P. 15; V. I, 

 5; width of head 1.78 in its length ; snout 3.75; eye 3.20; interorbital 

 space 2.67; first dorsal spine 1.78; first dorsal ray 1.60; third anal 

 spine 2.50; first anal ray 1.67; least depth of caudal peduncle 2.29; 

 pectoral 1.14; ventral 1.50; thirty-three scales in a lateral series from 

 gill-opening above to caudal base and three more large ones on the 

 latter; eleven scales from the vent upward and backward to the soft 

 dorsal ; eighteen predorsal scales. 



Body rather high, strongly compressed, deepest at the origin of 

 spinous dorsal ; dorsal profile convex, gradually descending anteriorly, 

 ventral profile much more convex than the former ; head small, sub- 

 coniform; snout short, rather broad, truncated in front; interorbital 

 space more or less convex; eye moderate, anterior, with no adipose 

 eyelid; mouth subinferior, its angle reaching a vertical through ante- 

 rior border of posterior nostril, the cleft three times as broad as 

 deep ; mandibular angle obtuse, symphysis forming a small knob, 

 which fits into a depression above ; extremity of maxillary entirely 

 hidden; teeth none on lioth jaws; upper lip fleshy; lower lip thin, with 

 sharp edge ; lower pre-orbital edge finely serrated ; nostrils separated, 

 the anterior a simple pore, nearer to extremity of snout than orbit, 

 the posterior slightly larger than the former, semilunar, with a cu- 

 taneous membrane, situated midway between anterior nostril and orbit 

 above; isthmus elongate, lanceolate, slightly constricted at middle. 



Scales in an even longitudinal series, rather thin, round ; head scaly, 

 smaller scales below, extending forward on snout though not quite 

 to its edge ; a sharply pointed scaly flap along the spinous dorsal base ; 

 pectoral with a short scaly flap ; a slender pointed scaly flap at the 

 root of ventral; a broad scaly flap between ventral bases; base of the 

 soft dorsal, anal, and caudal covered with small scales. 



Origin of the spinous dorsal a little nearer base of caudal than tip 

 of snout, first and second spines subequal in length; soft dorsal in- 

 serted nearer origin of spinous dorsal than the base of caudal ; origin 

 of anal two scales in advance of that of the soft dorsal, midway be- 

 tween caudal base and origin of ventral ; pectoral elongate, scarcely 

 reaching to the origin of spinous dorsal, inserted in the middle of body
