the base of the ventral, the external maiidihular the base of the pectoral, whilst the internal are shorter. 

 Teeth— in a narrow uninterrupted band across the palate. J'wfs— dorsal spine as long as the head excluding the 

 snout sli"-htly serrated anteriorly in its upper third, and posteriorly in its whole extent: the length of 

 the base o1 the adipose dorsal 1/3 less than that of the rayed fin, and equals 1/2 the length of the interspace 

 between the two fins, in some specimens, as the one figured, it is much longer. Pectoral spme nearly as 

 lontr as the head, stronger than that of the dorsal, smooth externally, and with about 13 denticulations 

 internally Ventrals arise on a yertical line jnst behind the last dorsal ray. Caudal forked, upper lobe the 

 longer. CoZoMrs— brilliant yellow, with a black shoulder spot and about five black longitudinal lines. In some 

 specimens the mandibular barbels are white with a black streak. _ 



In this species the median longitudinal gi'oove extends further backwards to the base ot the occiiJital 



process, than in M. vittatus. , ^ , -r i>-r tt- ^ •• coo n i.i ^ 



In some Punjab specimens (? Fimelodus anisurus, McClelland, Cal. J. N. Hist, ii, p. 583.) the nasal 



)iarbels are not so long as the head, whilst the maxillary only reach to the middle of the pectoral fin.

Leno-th of head 6t, of caudal 4^, height of body 5 in the total length. JJ/zft^-diameter 3 to 3^ m the length 

 of head about 1 diameter from end of snout and also apart. Profile from snout to dorsal fin rather elevated^ 

 Greatest width of the head equals its length excluding the snout : upper jaw slightly the longer, bummit ot 

 the head rough : median longitudinal groove extends nearly to the base of the occipital process whicli last is 

 three times as long as wide at its base, whilst there is no interspace between it and the basal bone of the dorsal fin. 

 Barbels— the nasal half as long as the head, the maxillary reach the middle of the anal fin, the outer mandibular 

 the middle of the pectoral, whilst the inner are rather shorter. ree^A— in an umnterrupted crescentic band 

 across the palate. Fu^s— dorsal spine of moderate strength, as long as the head excluding the snout, two or 

 three teeth anteriorly, sen-ated posteriorly : the length of the base of the adipose dorsal equals that of the rayed 

 fin but is about 1/4 less than the interspace between the two fins. Pectoral spme stronger _ than the dorsal as 

 lon'o- as the head behind the angle of the mouth, and with about 10 very strong teeth mternally. Caudal 

 deeply forked, the upper lobe being the longer. Colours-silvevj, lightest beneath, _a dark spot at^ the 

 conimencement of the base of dorsal fin, which is also black tipped, a darkish band likewise along the middle 



of the fin. . /. • 1 • 1 ii

Lcno'th of head 4f to 5, of caudal 5-1-, height of body 5 in the total length, ^i/es— diameter 4^ to 6 m 

 the leno-th Ii head. If to 2 diameters from end of snout, and H to 2 apart. The greatest width of the head 

 eciuals fts leno-th excluding the snout or behind the angle of the mouth, and is very httle more than its height, m 

 some specimens there is a considerable rise to base of first dorsal fin. Upper surface of the head roughened in 

 tubercles hardly forming lines, median longitudinal goove reaches to midway behind the hind edge ot the eye 

 and the base of the occipital process, which latter is rough, three times as long as wide at its base, and a short 

 (if any) interspace existing between it and the basal bone of the dorsal fin : radiating rough lines on the opercle : 

 shoulder bone with its triangular portion a little longer than wide at its base, and roughened m raised lines. 

 Barbels— the maxillary reach the ventrals, the nasal the opercle, the external mandibular the first third ot t le 

 pectoral spine, whilst the internal are shorter. Teeth-in an uiiinternii,ted semilunar band acToss the palate. 

 k«.s-dorsal '^"3 as high as the body, its spine half as long as the head with 2 or 3 teeth anteriorly m 

 the young, whUst it is finely serrated posteriorly : lengthof the base of the adipose dorsal vanes in some specimens 

 it usually equals that of the interspace between the two fins, and a little more than the length ot the 

 rayed fin. Pectoral spine strong, as long as the head excluding the snout, denticulated internally with about 

 16 coarse teeth. Ventral reaches from 1/2 to 2/3 of the distance to the base of the anal. Upper caudal obe

 the middle of the side, and a nari-ow light one above and below it, a dark shoulder spot, and sometimes another 

 near the base of the caudal fin. More tS the e^istward as Orissa and Bengal (PI. xcix f. 4) the colours are more
