depth 3|; D. ii, 8; A. iii, 11, i; scales 36 in 1. 1. to caudal base, 

 and 4 more on latter; 5 scales above 1. 1.; 3 scales below 1. I. to 

 ventral origin; 3 scales below 1. 1. to anal origin; 9 scales before 

 dorsal to occipital process; snout 3f in head; eye 3; maxillary 2|; 

 interorbital 3; length 34 mm. 



It appears related to Creagndus affinis Steindachner,'' Creagrutus 

 magdaleiue Eigenmann/ and Creagrutus hrevipinnis Eigenmann,* 

 all of which, however, have no dark caudal spot. Creagrutus avary 

 has three teeth, rather enlarged, forming its posterior premaxillary 

 series.

Head 3^; depth 3; D. ii, 8; A. iii, 23, i; P. i, 10; V. i, 8; scales 

 35 in 1. 1. to caudal base and 3 more on latter; 5 scales above 1. 1.; 

 4 scales below 1. 1. to ventral origin, or to anal origin; 12 predorsal 

 scales; head width 2 in its length; head depth at occiput 1^; snout 

 4; eye 2f ; maxillary 2f ; interorbital 2^; first branched dorsal ray 

 lyV; first branched anal ray If; least depth of caudal peduncle 2|; 

 pectoral lyV; ventral 1|. 



Body elongate, moderately compressed, lower profile a little more 

 convex than upper, greatest depth at dorsal origin, and edges all 

 convexly rounded. Caudal peduncle well compressed, length about 

 f its least depth. 



Head moderately large, compressed, profiles convex with upper a 

 little more bulging, and flattened sides very slightly constricted 

 below. Snout convex over surface and in profile, short, and its 

 length half its width. Eye large, rounded, though deeper vertically 

 than horizontal width, midway in- head depth, and hind pupil edge 

 about midway in head leng-th. Pupil vertically ellipsoid. Eyelids 

 narrow, free, not adipose-like. Mouth small, terminal, broad, very 

 short in commissure. Lips thick, fleshy, firm. Maxillary slender, 

 oblique, extends back about opposite front eye edge, free distally 

 short extent, and upper edge largely slips below preorbital. Teeth 

 quincuspid, with median point to each largest. Upper teeth biserial, 

 outer in an irregular row of small ones, and inner row of 5 large, 

 broad ones. No maxillary teeth. Mandible with single series of 

 large teeth in front. Inner buccal folds broad. Tongue broad.
