Nemachilus panguri, sp. nov. 



D.3/8; A.2/5; \\9; \'.7; C'.U. 



The liuilil of Nemachilus panguri is mure or less nf tlie same type as in the twu pre- 

 ceding species. i'lie iiead ami the anterior ])art •<( tlie IhkIv are sumewliat deprcsseil wliile 

 tlie tail region is siigiitly compressed and wiiip-likc. The head is moderately long and 

 broadly pointed anteriorly; its length is contained from 5-5.6 times in the total length and 

 from 4-4.6 times in the length of the caudal. Tlie width of the head is contained from 

 1.78-1.95 times and the heiglit of tlie head from 1.73-1.7() times in its length. The jiosition 

 of the eye in the length of the head is varialile: the upjier margin of the orbit is slightly 

 raised above the dorsal profile of the head and the eyes are not visible from the ventral sur- 

 face. The diameter of the eye is contained from 4-5 times in the length of the head, from 

 1.5-2 times in the length of the snout and frnm 1-1.1 times in the interorbital width. The 

 mouth is small, lunate, transverse and horizontal; it is situated on the ventral sm^face slightK'

behind the tip of the snout and is bordered by llesiiy and papillated li])s. i'he lower lip is 

 interrupted in the middle. The posterior iaw is sharp, truncate and horizontal. Ibe three 

 ])airs of barl)els are fairly well de\elo]ied : the inner mstrals are as long as or slightly longer 

 than the diameter of the eye while the other two ])airs are much longer. 



The depth of the body is cf)ntained from 9-10.5 times in the total leui^th and from 

 7.3-8.6 times in the length witliout the caudal, liehind the gill-opening and abo\e the base 

 <if the pectoral tin, the lateral line is represented In- a thin-walled, broad tulx; beyond whicli 

 it is faintl}' marked to the l)ase of the caudal flu. The caudal ]icdunclc is long and narrow; 

 its least height is contained from 5.3-6.5 times in its length. In both the sexes the least 

 height of the caudal peduiK'le is usualh' le>s ilian the diameter ol the eye, but in some 

 female specimens it is greater than the diameter of the eye. 



The dorsal fin is inserted slighth' in advance of the vcntrals and its coniuKiuement is 

 either equidistant l>etween the tip of the snout and the base of the caudal or nearer to the 

 tip of the snout than to the base of the caudal; it is almost as long as the head; its jiosterior 

 border is slightly arched. The ])aired fins arc broad and horizontal ; the pectorals arc ])ointed 

 in the middle, especially in the males. The pectoral fin is considerably shorter than the head 

 and is .separated from the ventral by a distance almost equal to half of its length. The ven- 

 trals extend beyond the anal ojjcning and reach the base of the anal fin. The anal fin is 

 similar in shape to the dorsal. The caudal fin is almost as long as the head; it is slightly 

 eniarginate with the upper lobe considerably longer and better developed than the lower.
