368 (Tokyo). 



Hahitaf. — Southern Japan, north to Tok^'o. 



Head 2.8 in length without caudal; depth 7.75; depth of head 

 3.25 in its length; width of head 1.5; eye 4.2; interorbital space 3 

 in eye; maxillary 2.5; D. I-VIII-11; A. 11; scales 75; lateral line 

 smooth. 



Head moderately armed; superciliary ridges each with about 6 

 low" and rather closely approximated serratures, in front of and 

 beliind each ridge a single higher spine; infraorbital ridges with 5 

 distant spines, the last one just in iront of the base of the long pre- 

 opercular spine; two smooth ridges on upper part of opercle, each 

 terminating behind in an inconspicuous spine; scapular ridges 

 short, each with two spines; parietooccipital region with a pair of 

 low" ridges, each terminating in a moderate spine; post-orbital 

 ridges ill-defined, each with two low spines; preopercular spines 3, 

 the upper more than twice the length of the second, and reaching 

 almost to the gill-opening, third spine about half as long as second; 

 a slight but sharp notch on the opercular membrane, imder the 

 second spine; anterior nostril with a short dermal flaj); teeth in fine 

 villiform bands on jaws, vomer, and palatines, the vomerine bands 

 short, and disposed lengthwise, scarcely reacliing past front of pala- 

 tines; no canines; tongue emarginate, with a very slight median 

 convexit}". No ocular cirrus. 



Spinous and soft dorsals of about equal height; longest dorsal 

 spine 2.2 in head; soft dorsal inserted slightly in front of anal; the 

 margin of the fui notched to a depth (measured on ray forming hinder 

 boundary of notch) equal to two-fifths of the diameter of the orbit; 

 pectorals 2 in head, reacliing to opposite sixth ray of spinous dorsal; 



a A nominal point of difference between Bleeker's figure of this fish and Giinther's 

 figure of P. rudis consists in the absence in the figure of Bleeker of the third (lowest) 

 preopercular spine. In \'iew of the perfect agi'eement of the figures in all other essen- 

 tial particulars, it appears that the point may be waived with entire safety.
