torals 0.75 head, equal to ventrals and extending slightly beyond 

 their base. 



Color: Plain silvery, a round dusky spot on caudal peduncle; 

 fins hyaline. 



Type. — A specimen 13.0 cm. long taken in the Tapi Kiver near 

 Bandon, Peninsular Siam, September 30, 1923. Cat. No. 90294, 

 U.S.N.M. 



Other spedTTiens. — The collection of the Siamese Department of 

 Fisheries contains a specimen 16.0 cm. obtained from Bandon Bight, 

 Gulf of Siam, September 19, 1923, where it had evidently strayed 

 in the flood water from the Bandon River; and a second specimen, 

 12.0 cm. long, from the Tapi River near Bandon, September 30, 

 1923, which shows faintly a dark brown spot at the base of each 

 of the scales on back and sides and a small round dark brown spot 

 on caudal peduncle at base of fin. 



Remarks. — This species is closely related to C . armatus, known 

 from Sumatra, Java, and Borneo as well as from Siam, but dif- 

 fers therefrom in having a much less steep and arched dorsal pro- 

 file, more slender body, more elongate caudal peduncle, and plainer 

 coloration. From Bleeker's C. duvierili^ known from a single speci- 

 men from Bangkok and imperfectly described by Sauvage,^ this 

 form appears to differ in having a longer head, larger eye, more 

 scales in transverse series, and longer dorsal fin arising well behind 

 the origin of ventrals instead of a little in advance. 



This fish at Bandon is known as pJa hamprad (slippery fish). 

 It is reported to be a small form, not exceeding in size the largest 

 specimen herein listed. 



PUNTIUS WETMOREI, new species 



DescHption. — Form elongate, moderately compressed, dorsal and 

 ventral profiles similar; back slightly arched, a slight concavity at 

 nape; depth 2.6 in standard length; least height of caudal peduncle 

 about equal to eye and 0.8 its own length ; head 4 in length ; eye large, 

 equal to snout, 0.2 less than postorbital part of head and 1.3 in inter- 

 orbital space; snout rounded, jaws nearly equal, lips thin, mouth 

 small, maxillary not reaching vertical from anterior margin of eye; 

 barbels 4, short, rostral pair reaching eye, maxillary pair longer but 

 less than diameter of eye; scales large, 23 or 24 in lateral line, 

 5.5-1-4.5 intransverse serise, 8 before dorsal, 12 surrounding nar-
