NO. 1688. yEW FISHES FROM JAPAX— SNYDER. QQl 



fin -with a similar dark border Avhich extends forward and ends near 

 the middle of lower ed<^e of caudal peduncle; scales of body each with 

 a dusky spot, the spots growing- less distinct and finally disappearing 

 ventrally; posterior basal part of soft dorsal with a light, yellowish 

 spot, round and well defined in some examples ; other parts of fin, 

 together with spinous dorsal, dusky; anal with a well marked blackish 

 border. 



Described from the type, a specimen TO nun. long, and other ex- 

 amples from Naha, OkinaAva, among which are the cotypes, Cat. Xo. 

 21134, Stanford University Collection.

The species resembles P. cyanom^is Bleeker." It is distinguished 

 by the black spot on the base of the pectoral, the absence of a blue 

 spot at upper edge of gill-opening, the less sinuate dorsal, and other 

 less conspicuous characters. 



Xamed for Mr. Robert Earl Richardson. 



ABUDEFDUF REX, new species. 



Head, 3.G in length to base of caudal; depth, 2.4; depth caudal 

 peduncle, G.4; diameter eje, 3 in head; width interorbital space, 

 3.3 ; D. XIII — 14 ; A. II — 13 ; scales in lateral series, 25 ; between 

 lateral line and spinous dorsal, 2 ; between origin of anal and lateral 

 line, counting upward and forward, 9. 



Body moderately elongate, the q\q large, snout short and blunt, the 

 7uaxillary extending to a vertical j^assing midway between pupil and 

 anterior edge of orbit. Teeth in a single row ; conical and close set. 

 Gill-rakers on first arch 5-f-ll; slender and rather short; suborbital 

 smooth ; edge of preopercle exposed and smooth. 



Lateral line ending below origin of soft dorsal ; a number of pores 

 scattered along middle of caudal peduncle. Snout and chin naked; 

 head and body elsewhere scaled ; bases of dorsal and anal with a 

 strong sheath of scales, above which several rows of narrow, thin 

 scales extend outward on the membranes; basal half of caudal with 

 scales. 



Membrane of spinous dorsal with a scalloped edge, a small filament 

 extending beyond each spine; the posterior spines longest, about l.G 

 in head ; last rays extending somewhat beyond base of caudal when 

 depressed. Second spine of anal almost equal in length to the fol- 

 lowing ray, l.G in head ; longest raj^s somewhat shorter than those of 

 dorsal, not quite reaching caudal when depressed. First ray of ven- 

 tral filamentous, reaching slightly beyond origin of anal when de- 

 pressed, the spine about half as long as the ray. Upper rays of the 

 pectoral longest. 3.8 in the length ; the others successively shorter. 

 Caudal Avith a rather shallow notch, the lobes rounded.
