width a little less than half of exposed depths. Snout, interorbital, 

 preorbital, muzzle and lower limb of preopercle anteriorly, naked. 

 Cheek with 2 rows of broad scales. Several large scales on opercle. 

 Fins, except base of caudal which covered with large scales, naked. 

 Smaller scales along bases of dorsals and anals. Round scale between 

 ventral bases about ^ of fin, and pointed axillary scale about 2|. 

 Lateral line concurrent with back, slopes down below bases of last 

 dorsal rays and midway along side of caudal peduncle on caudal 

 base. Tubes in first section of lateral line with several branches, 

 all small, main stem most conspicuous and branches small. 



Origin of spinous dorsal about over that of pectoral, spines more 

 or less equal, rather flexible adipose ends present, and edge of fin 

 entire. Soft dorsal origin little nearer upper corner of gill-opening 

 than caudal base, membranes very shallowly emarginate along fin 

 edge, and rays subequally high. Anal spines graduated to third, 

 which longest, each ending in flexible adipose-like end. Soft anal 

 like soft dorsal. Closed caudal slightly concave behind, when 

 expanded nearly truncate and corners always sharp-pointed. Pec- 

 toral broad, upper rays longest, and fin | to anal. Ventral inserted 

 about opposite pectoral origin, fin about f to anal, and spine ends 

 in flexible adipose-like tip f of fin length. Vent close before anal. 



Color in alcohol faded pale brownish with traces of olivaceous. 

 Dorsals marginally with broad pale band length of both fins. Anal 

 with similar submarginal band lengthwise. Caudal uniform brown- 

 ish. Pectoral pale olive, but second, third and upper portions of 

 fourth branched rays with their intervening rays dark brown, forming 

 a lengthwise dark band. Ventral pale uniform brownish. Upper 

 lip broadly pale, and with narrow line from mouth corner back to 

 eye. Also short pale line from behind eye over postorbital, besides 

 several smaller ones below, at lower edges. Small broken bars and 

 spots of pale brownish on under surface of head. Iris slaty. 



Length 215 mm. 



Type, No. 47,548, A. N. S. P. 



Philippine Islands. Presented by the Commercial Museums of 

 Philadelphia. 



This species somewhat resembles Calhjodon rivulatus (Valenciennes) 

 as figured by Bleeker,*^ but differs in the coloration, as there are no 

 traces of the green median spots on the soft dorsal, the dark pectoral 

 band is lower on the fin, and it does not show the spots and bars of 

 pale color on the under surface of the head.
