extremes of the present genus are connected by intermedíate grada- 

 tions, of which the Pl. nasuta of McClelland presents a good illus- 

 tration.* 



A highly typical species, vvith every character developed in the 

 utmost degree, may be designated — 



Pl. notata, nobis, n. s. Easily recognized by having five conspi- 

 cuous black spots on the base of its dorsal fin. Four labial cirri, 

 the hindmost liable to be overlooked. Scales on lateral line 33, and 

 8 from dorsal to ventral : the dorsal rather high and fálcate ante- 

 riorly. Yentrals as large as the pectoral?, and somewhat fálcate ; 

 the anal more decidedly so. 



D. 10.— A. 7.—P. 15.— Y. 9.—C. 20. 



Colour clusky olive-green above and on the sicles, beneath buffy- 

 albescent. Base of the dorsal fin whitish, setting oíf a series of 

 black spots, larger anteriorly and tlie hindmost generally obsolete ; 

 rest of the fin a little nigrescent. One or more spots also at base of 

 the anal fin. Pectorals somewhat yellowish at base, then blackish : 

 a dusky line along each longitudinal row of scales becoming gradually 

 visible towards the tail. Length 6 to 6¿ in. Tenasserim. 



The next has a smooth muzzle and almost rudimentary disk. 



Pl. latius ; Cyprinus latius, B. H. : Gonorhynchus macrosomas, 

 McClelland. Tenasserim. 



Labeo curchius ; Cyprinus curcJiius, B. H. What I take to be 

 this species accords with the fin-ray formula assigned by McClelland 

 (As. Res. XIX, II, 328) ; but I count only about 6A (instead of 78) 

 rows of scales along the lateral line, and but 17 or 18 (instead of 30) 

 rows from dorsal to ventrals. No proper " stripe along the middle 



Nathus, Dr. Heckel refers the Varicorhinus diplostomus of the FiseJie aus 

 Caschmir, by the new specific ñame of Valenciennesii ; and the Barbus dipla- 

 cheilus of the same work is now his T. baebatulus. A third species, from tlie 

 Bombay Presidency, is also described by him as T. porcellus. (Viáe Fauna 

 von Kasehmir, pp. 376, 378, and 385). The trae Varicokhinus of Küppell lias 

 Bpines to the dorsal fin; wherefore V. bohree of Sykes also cannot properly be 

 retained in it. 



* I think, howerer, that the so-called ' Mountain Trout' ofKumáon, figured 

 by Mr. McClelland in J. A. S. IV, 40, with its minute scales and other striking 

 distinctions, is erroncously placed by him in this particular group in As. lies, 

 XIX, II, 281, 367,
