AKT. 7 NEW SIAMESE PISHES SMITH 15 



tinuous, lower lip with a postlabial groove which is interrupted in 

 the middle by a short space ; a sulcus separating lower lip from lower 

 jaw, which is included and has a horny covering ; rostral and maxil- 

 lary barbels well developed, the former inserted at the base of the 

 rostral groove ; scales large ; dorsal fin with 8 branched rays, its last 

 simple ray osseous, stout, and strongly denticulated; anal with 5 

 branched rays, its simple rays unossified; gill-membranes joined to 

 isthmus. 



This genus resembles Li^sochilus from Southern Asia and Sumatra, 

 in having the lower jaw covered with a horny sheath and a deep 

 sulcus separating it from the lower lip. The pores on the snout in 

 Lissochilus are surmounted by horny tubercles which extend to be- 

 low the eye, and the last simple dorsal ray is weakly ossified and not 

 denticulated. There is no rostral groove. 



In Puntius the last simple dorsal ray may be ossified and serrated, 

 but there are no pores on the snout, no horny sheath on lower jaw, 

 and no rostral groove. 



In the Bleekerian genus Barhodes, which Weber and Beaufort 

 place in the synonymy of Puntius, the essential character is the pos- 

 session of 4 barbels. The Indian cyprinids placed by Day (Fishes of 

 India) in the B art odes group of the composite genus Barhus include 

 some forms which have the last simple dorsal ray denticulated and 

 one of those species, B. chaganio^ has pores on the snout and other 

 parts of the head ; this fish, however, has no horny covering on the 

 lower jaw and no rostral groove; and in the only Indian species {B. 

 litho'pidus) mentioned as having a covering on the lower jaw (Day's 

 description reads : " a thin cartilaginous covering internally to either 

 jaw ") the last simple dorsal ray is not denticulated or even osseous 

 and there are no rostral pores. The type species of Barhodes as 

 designated by Bleeker is helinka, known from Sumatra and Malacca. 

 It has the last simple dorsal ray coarsely denticulated, no rostral 

 pores, and no rostral groove. 



POROPUNTIUS NORMANI, new species 



Desoription. — Dorsal and ventral outlines similar; depth 3 in 

 standard length ; least depth of caudal peduncle 1.5 in its length and 

 2 in head; head 4 in length; eye large, close to upper profile, 3.2 in 

 head, equal to snout, slightly less than flat interorbital space; snout 

 obtusely rounded, slightly overhanging the upper lip which is sepa- 

 rated from the snout by a deep groove; middle third of snout with 

 a short vertical groove on each side and with transverse rows of pores, 

 a few pores also on snout distal to the rostral groove ; mouth strongly 

 arched, lower jaw included, maxillary extending to a vertical from 

 anterior margin of eye ; rostral and maxillary barbels equal, as long
