line pore 12; outer rays of pelvics elongate, reaching to anus; distal 

 margin of caudal fin a little rounded; first two spiny dorsal rays 

 somewhat elongate, flexible, the membrane between second and third 

 spines deeply incised but connecting basally with third spine; scales 

 in area between pelvic and pectoral bases and anal origin about half 

 the size of those on middle of sides; middorsal line of head and snout 

 with fleshy keel. 



Color in, alcohol. — Background light brown, a prominent dark spot 

 above lateral line and opposite lateral line pore 15; traces of about 5 

 vertical dark bars first near origin of dorsal, second below dorsal 

 spine VI, third below dorsal soft rays 2 and 3, fourth below dorsal 

 soft raj^s 8 and 9, and fifth at base of caudal fin.

Description. — Dorsal rays IX, 12; anal 111,12; pectoral ii,10-ii,ll; 

 branched caudal rays 5 + 5; pores in lateral line 20 + 6; scales above 

 lateral line to base of first soft dorsal ray 2, and below to anal origin 

 10; gill rakers on first arch 6 + 1 + 12. 



Head 3.1; greatest depth 2.5; longest pectoral ray 4.2; snout tip to 

 anus 2.0; snout to dorsal origin 3.2; all in standard length. Snout

 eye in fleshy interorbital space 1.2. 



Dorsal profile of snout forming an angle of about 90 degrees with 

 ventral contour of head; pectoral fin reaches to opposite lateral fine 

 pore 11 ; outer rays of pelvics elongate, reaching to anus; distal margin 

 of caudal fin a little rounded; first two spiny dorsal rays flexible, a 

 little elongate, the membrane between second and third spines deeply 

 incised but connecting basally with third spine ; scales in area between 

 pelvic and pectoral bases and anal origin about % to Yi the size of 

 those on middle of sides; middorsal line of head and snout with a 

 fleshy keel. 



Color in alcohol. — Backgi'ound light brown; a large blackish blotch 

 below lateral line pores 2 to 9 and just behind head on middle of side ; 

 this dark blotch covering 7 or 8 vertical and lengthwise scale rows; 

 middle of caudal peduncle with a dark oblong blotch; a fainter dark 

 area, 2 or 3 scales in diameter occurs on midside equidistant between
