The height of the body is contained 2§ times in the total 

 length (without caudal), the lengtli of tlie head 2| times. 

 Snout produced, with the upper jaw slightly the longer, 

 longer than the postorbital portion of the head. Mouth of 

 moderate width, very sliglitly oblique, the maxillary reaching 

 but little beyond the vertical from the nostril. Teeth small, 

 subequal, with brown pointed tips. The eye is a little less 

 than one half of the length of the snout and contained 4| 

 times in that of the head ; its diameter does not equal the 

 width of the interorbital space in the largest specimen. Pr«- 

 orbital as wide as the eye. Prasoperculum with a broad 

 scaleless inferior limb, but its width is much narrower than 

 the cheek, on which the scales are arranged in four series. 

 The dorsal fin commences above the root of the pectoral fin ; 

 its spines are of moderate strength, the middle ones being 

 much longer than the eye. Caudal fin slightly emarginate. 



Specimens from Azumin^ Creek have sixteen dorsal spines 

 and the pectoral fin reaches nearly the vent. Two faint 

 broad longitudinal bands on the upper half of the body are 

 crossed by five or six transverse bands, equally faint, the 

 parts crossed being of a darker tint. These markings are 

 more distinct in young examples than in the adult. An 

 opercular spot. 



Specimens from Kondo-Kondo have fifteen dorsal spines 

 and a rather shorter pectoral. None of the markings are 

 present beside the opercular spot.
