50 MEMOIRS OF THE CARNEGIE MUSEUM 



Head 2.5; depth 2.73; eye 4 in head; interorbital 5; snout 4.25; maxillary 2; 

 width of maxillary in eye 1.4; depth of caudal peduncle in head 3.16. D. XIII, 

 13; A. Ill, 5; pores in lateral line 33; series of scales along lateral line about 62. 

 Body rather short, high, and compressed; greatest depth through base of 

 pectoral; back sloping gently behind and rather abruptly in front of this; profile 

 almost straight from nape to snout; head nearly as deep as long; maxillary 

 reaching well behind eye, posteriorly quite broad; suborbital narrow,, less than 

 half as broad as maxillary, bearing two blunt processes anteriorly; preopercle 

 with five short processes, the lowest small; upper angle of opercle with two 

 sharp processes; lower margin with two smaller ones opposite middle of pre- 

 opercular spine; humeral spine present, short, flat, sharp; occiput and inter- 

 orbital scaly, almost flat, the armature moderate; preorbital and postorbital 

 spines form a continuous ridge above eye; parietal and tympanic spines small, 

 not elevated; nasal spines prominent. 



Spinous dorsal moderately high, rounded; fourth and fifth spines longest, 

 1.8 in head; notch between dorsals obtuse, the membrane of first dorsal con- 

 fluent with that of second for one-third its height; soft dorsal truncate, as high 

 as third spine of first dorsal; last three, rays only are graduated; caudal bluntly 

 rounded; anal short, high, truncate, its rays as long as fourth dorsal spine; 

 second spine equal to third in length, and much stouter; ventrals inserted be- 

 hind pectoral base, tips almost reaching anal; pectoral broad, rounded, its lower 

 rays thickened. 



Body and head, except snout, preorbital and jaws, covered with strongly 

 ctenoid scales, those of occiput, interorbital and temporal regions abruptly 

 smaller; soft fins scaled at base with minute, numerous scales; peritoneum 

 white; gill-rakers 7 -\- 18, rather slender, compressed, longest about .4 diameter 

 of eye. 



Color dusky, lighter below; fins all dark, tipped with black, except the 

 lower half of pectoral which has a broad, white margin; snout and top of head 

 almost black. 



Described from the type, 160 mm. long, taken at Fusan, Korea, by Dr. 

 Jordan (No. 4172a). 



This species is near Sebastodes schlegeli (Hilgendorf) (Plate X, fig. 1), but 

 is readily distinguished from this by the small number of pores (33 instead of 

 46) in the lateral line, and by other less conspicuous characters. It is named 

 for Professor Isao Ijima, of the Imperial University of Tokyo, to whom we are 

 indebted for many favors.
