 striae ; lateral line complete, moderately decurved ; 31 scales in longi- 

 tudinal series, 5.5-1-4.5 in transverse series, 2.5 rows between base of 

 ventrals and lateral line, 11 between dorsal fin and nape, 14 around 

 narrowest part of caudal peduncle. 



Fins: Dorsal origin over base of ventrals, rather nearer to snout 

 than to base of caudal; dorsal rays iii,8; the last simple ray stout, 

 with strong serrations, its length with soft tip 1.5 in depth of body 

 and equal to distance from anterior nostril to posterior border of 

 head, its osseous part equal to head less snout; dorsal margin slightly 

 incised; caudal forked, somewhat longer than head; anal rays iii,5, 

 the unbranched rays weak, longest ray equal to third simple dorsal 

 ray, margin of fin truncate; ventrals and pectorals subequal, 1.25 in 

 head, ventrals with a long axillary scale at base. 



Color: Above dull greenish, sides and below silvery, with faint 

 dark longitudinal lines on back and sides following rows of scales; 

 a dark area on posterior part of caudal peduncle ; margin of dorsal 

 and caudal dusky, other fins plain. 



Type. — ^A specimen 10.5 cm. long taken at Pliew waterfall on Kao 

 Sabap, near Chantabun, Southeastern Siam, April 9, 1925. Cat. No. 

 90297, U.S.N.M. 



Remarhs. — This species is as yet represented by only the type, 

 which was collected by Luang Masya Chitrkarn, of the Siamese De- 

 partment of Fisheries. The fish appears to be known to local fisher- 

 men and is called pla kaow. 



I take pleasure in naming this species after Mr. J. R. Norman, in 

 charge of the collection of fishes in the British Museum.
