FRESH-WATER FISHES OF SlAM, OR THAILAND 325 



Remarks. — This species most closely resembles N. muUifasciatus Day 

 (q. v.), showing the same peculiarity of the dark cross bands, which 

 are extremely narrow and crowded on the anterior half of the body, 

 wider and more widely spaced posteriorly. In the present species, 

 however, the cross bands are much more numerous and are supple- 

 mented by dark saddles, which constitute a series of marks distinct from 

 the cross bands. The final cross band, which is jet black, extends ver- 

 tically completely across the peduncle according to Day's figure of N. 

 rrmltifasciatiis, but in the present species is crescentic, does not reach the 

 upper and lower profiles, and is supplemented superiorly by a black 

 saddlelike spot on the fulcral caudal rays. Whereas in N. nrnlti- 

 fasciatus the origin of the dorsal fin is definitely in advance of the 

 ventrals and midway between the tip of the snout and the base of the 

 median caudal rays, in the present form the dorsal arises directly 

 over the origin of the ventrals and is nearer to the base of the caudal by 

 the length of the snout. 



Many of the specimens are ovigerous females approaching the spawn- 

 ing condition ; these range in size from 5.Y to 7.1 cm. and average 6.2 

 cm., and have the markings less distinct than in the males, which 

 average somewhat smaller. 



The specific name (from pocidum, a bowl) is given in allusion to the 

 mountain on which the specimens were collected, Angka meaning 

 crow's bowl.

This is one of the most widely distributed of the Thailand noema- 

 cheilids. The type came from the upper waters of the Tadi rivulet, 

 which flows from the high mountains of the Thailand-Burmese bound- 

 ary, through the town of Nakon Sritamarat, into the Gulf of Siam. 

 Other specimens from Peninsular Thailand were from a stream and 

 a pond in Ronpibun, Province of Nakon Sritamarat. In Southeastern 

 Thailand the fish was collected in a ditch near the town of Chantabun 

 and in a mountain stream on Kao Sabap. More recently specimens 

 have been obtained by Fowler from the Central region at Khao Nam 

 Poo and Mepoon, and in the Northern area at Chiengmai. Deignan, 

 collecting for the U. S. National Museum, got five specimens, 5 to 6 cm. 

 long, from Huey Aw, a clear brook tributary of the Menam Nan, 

 Northern district, April 21, 1936, two of these specimens having a 

 preorbital hook ; and three specimens, 5.9, 6.2, and 6.5 cm. long, from
