extremes of the present genus are connected by intermediate grada- 

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

 tration.* 



A highly typical species', with every character developed in the 

 utmost degree, may be designated — 



Pl. 2TOTATA, 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 falcate ante- 

 riorly. Yentrals as large as the pectorals, and somewhat falcate ; 

 the anal more decidedly so. 



D. 10.— A. 7.— P. 15.— V. 9.-0. 20. 



Colour dusky olive-green above and on the sides, beneath buffy- 

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

 black spots, larger anteriorly and the 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 nest has a smooth muzzle and almost rudimentary disk. 



Pl. latils ; Cyprinus latius, B. H. : Qonorhynchus macrosomus, 

 McClelland. Tenasserim. 



Labeo cuechils ; Cyprinus curchius, 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 61 (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 



KATHTJ3, Dr. Heckel refers the Varicorhinus diplostomus of the Fisohe aus 

 Caschmir, by the new specific name of Valenciennesii ; and the Barbus diplo- 

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

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

 von Kaschmir, pp. 376, 378, and 38.5). The true Varicorhinits of Ruppell has 

 spines to the dorsal fin; wherefore V. bobree of Sykes also cannot properly be 

 retained in it. 



* I think, however, that the so-called 'Mountain Trout' ofKumaon, figured 

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

 distinctions, is erroneously placed by him in this particular group in As. Ses. 

 XIX, II, 281, 367.
