618 PHYSOSTOMI. 



Nemacheilus Denisonii, Day, Proc. Zool. Soc. 1867, p. 287 ; Giinther, Catal. vii, p. 352. 



B. iii, D. 10(1), P. 11, V. 7, A. 7(1), 0. 17. 



Length of head 5 to 5i, of caudal 6|, height of body 64 in the total length. Hyes — situated in the 

 anterior half of the head, diameter 1/6 of length of head, 2 diameters from end of snout, and also apart. The 

 greatest width of the head equals its length excluding the snout. Ba/rbels — the maxillary extend to the 

 opercle, the rostral pairs are shorter. Fins — the dorsal commences midway between the end of snout and 

 base of caudal, which last is lobed. Pectoral extends rather above 1/2 the distance to the ventrals. Scales— 

 minute. LateraZ-Zme— complete. Colowrs — reddish brown, having from nine to twelve dark vertical zones, 

 those anterior to the dorsal fin sometimes coalescing rather irregularly across the back. Dorsal fin with three 

 rows of fine black spots and a black base. Caudal irregularly spotted in bands. Some dull spots on the 

 ventral and anal fins. Most of the head marbled with black dots. 



There is a variety of this fish at Poena and elsewhere in the Deccan, its dorsal and caudal fins are more 

 spotted, whilst its body bands are more numerous having less width of ground colour. 



Habitat. — Neilgherry and Coorg hills, and rivers at their bases ; Mysore and the Deccan. The example 

 figured was from the Neilgherries. 



16. Nemacheilus notostigma. 



Bleeker, Verh. Holl. Maatsch. Haarl. 1864, Cobit. et Cyp. Ceylon, p. 5, t. i, fig. 2 ; Giinther, Catal. vii, 

 p. 352. 



B. iii, D. 10(f), V. 7, P. 13, A. 7-8(''i»), C. 19. 



Length of head 5^ to 6, of caudal 6, height of body 5| in the total length. Hyes—diaxixeiev 6 in 

 length of head, 2 diameters from end of snout, \\ apart. Snout compressed and pointed. Barbels — all rather 

 longer than the eye. i^ms— dorsal highest in front, it arises midway between the snout and base of caudal 

 fin, being a little in advance of the ventrals : it is not quite so high as the body below it. Pectoral nearly as 

 long as the head. Caudal lobed in its posterior third. Scales — indistinct. Colours — with ten to fourteen 

 vertical bands on the body, broader than the interspaces. A dark mark at the base of the caudal, which is 

 banded. A black spot at the base of the anterior dorsal rays, and a bar across the lower portion of the fin 

 in its last half, a single band across its centre. 



This fish is very similar to N. Denisonii, but has a shorter head, a more compressed snout and rather a 

 lower dorsal fin. N. multifasciatus is also very similar, but has a much smaller eye. 



Habitat. — Ceylon. 



17. Nemacheilus zonalternans.

B. iii, D. 2/9, A. ll(f)P. 11, V. 9, A. 7(i-), C. 19. 



Hyes — of moderate size, rather above 1 diameter from end of snout. Fims — dorsal arises anterior to the 

 insertion of the ventral, and rather nearer the snout than the base of the caudal, which latter fin is entire. 

 Scftjies —distinct. Oo?ows— ten to eleven bars descend down the lower 2/3 of the body to the abdomen, with 

 intermediate half bands superiorly between them. Dorsal and caadal fins spotted in bands. 



Habitat. — Tenasserim Provinces, from whence Major Berdmore sent two specimens, 1'4 and 1-6 inches 

 respectively in length. 



18. Nemacheilus ladacensis. 



Giinther, Catal. vii, p. 356 ; Day, Proc. Zool. Soc. 1876, p. 747, and Fishes, Tarkand, plate iv, fig. 4. 

 B. iii, D. 10(1), V. 9, A. 8(1), C. 19. 



Length of head 5, of caudal 5i, height of body 5J in the total length. i?2/es— diameter 5 to 5^ in 

 length of head, 2j diameters from end of snout and 2 apart. Free portion of tail 1/2 as high as long. 

 Barbels — the maxillary ones scarcely reach the front edge of the eye, the longest rostral ones to below the 

 front nostril, ii'ms— upper margin of dorsal oblique, with its anterior angle rounded, it commences between 

 the front edge of the eye and the root of the caudal, which latter is emarginate. Pectoral extends rather 

 above half way to the base of the ventral. ScaZes— absent. Colours — of a light fawn, with 16 or 18 

 interrupted darker and sinuous bands passing from the back down the sides : a silvery lateral band. Dorsal 

 and caudal finely spotted in lines : a darkish band on pectoral, ventral, and anal fins. 



Habitat. — Tibet, from whence two specimens were procured.
