Lentrth of head 4§, of caudal 5 to 6j, height of body 6 to 65 in the total length. J?(/e.s— diameters il in 

 the length" of head, I7 diameters from the end of snout, and '2 apart. The greatest width of the head 

 equals its length excluding the snout. Upper jaw slightly the longer. The upper surface of the head 

 roughened in closely set tubercular lines continued on to the occipital process, opercle likewise striated with 

 similar lines. Median longitudinal groove rather constricted in its centre, it reaches to opposite the hind 

 border of the preopercle. Occipital process narrow, three times as long as wide at its base and does not quite 

 reach the basal bone. Barbels — the nasal reach the opercle, the maxillary the middle of the anal fin, 

 the external mandibular the end of the pectoral spine, whilst the internal are shorter. Humeral process rather 

 short and pointed. Teeth— in an uninterrupted crescentic band across the palate. Fins— dorsal as high as 

 body, its spine with two or three teeth anteriorly near its summit and serrated posteriorly, it equals 

 3/7 of the length of the head : length of the base of the adipose dorsal equals that of the rayed fin or of the 

 interspace between the two. Pectoral reaches two-thirds of the way to the ventral, its spine is stronger than 

 that of the dorsal and equals the length of the head excluding the snout. The ventral does not reach 

 the anal. Up])or caudal lobe the longer. A well marked pre-anal papilla. CoZo^ra— silvery along the back, 

 becoming dull white beneath. A dark shoulder spot, a light band along the lateral-line, and a silvery one above 

 and another below it, dorsal and caudal black tipped, anterior half of anal dark. 



At the Jardin des Plantes I was allowed to examine one of M. LescheaauWs PondicheiTy specimens, still 

 in excellent preservation. The anal papiUa is very distinct. 



Eiihitat. — Madras to Pondicherry and inland to Coimbatore, also Ceylon, attaining about -1 inches in 

 length. Jerdon observes that it is also found in Mysore.

Length of head 4f in a Wynaad specimen to 5|, of pectoral 6 to 7, of caudal .5 to 6, height of body G to 

 7 in the total length. Eyes— diametevs 4 to 4^ in the length of head, li diameters from the end of snout, and 

 If apart. Scarcely any rise in the dorsal profile from the snout to the base of the dorsal fin. Greatest width 

 of the head equals it.s length behind the angle of the mouth. Upper surface of the head nearly smooth. 

 Median longitudinal groove extends to midway between hind edge of the eye and the base of the occipital 

 process, which last is about twice as long as wide, whilst there exists a considerable interspace between it and 

 the basal bone of the dorsal fin. The triangular portion of the shoulder-bone curves rather upwards, 

 and is 1/4 longer than deep at its base. Barbels— the nasal reach to a little behind the orbit, the maxillary 

 to the middle or end of the ventral fin, the external mandibular to the end of the pectoral, whilst the internal 

 are a little shorter. Teeth— in an uninterrupted crescentic band across the palate Fins — dorsal nearly 

 as high as the body, its spine weak, finely serrated or almost entire posteriorly, and one denticulation anteriorly 

 near its summit, its length equals that of the postorbital portion of the head: length of base of the 

 adipose dorsal 1/3 more than that of the rayed fin, or of the interspace between the two fins. Pectoral spine 

 strong and equal to the length of the head excluding the snout, internally with about eight or ten strong 

 denticulations, whilst it is roughened externally. "Upper caudal lobe the longer. Colours — deep leaden, 

 usually with a dark blotch on the shoulder surrounded by a lighter edge, another at the base of the caudal fin : 

 a dark band along the lateral-line, abdomen of a dull white. Fins with minute dark spots, making the upper 

 portion of the dorsal and the lower third of the anal blackish. 



Eabitaf.—^la\ahnr coast of India and the Wynaad, attaining upwards of 6 inches in length. The 

 specimen figured was from south Canara, where it extends inland to the ghauts.

Length of head 6i, of caudal b\, height of body 5| in the total length. iJf/es— diameters 5 in 

 the length of head, l^- from end of snout,"and 2 apart. A considerable rise from the snout to the base of the 

 dorsal tin. The greatest width of the head equals its height or its length excluding the snout. Upper surface 

 of the head roughened, the median longitudinal groove almost reaches the base of the occipital process, 

 which last is about three times as long as wide and reaches the basal bone of the dorsal fin : shoulder-bone 

 roughened in lines and 1/2 longer than deep at its base. Barbels — the nasal nearly reach the opercle, 

 the maxillary the end of ventral fin, the outer mandibiUar the end of pectoral spine, whilst the internal are 

 shorter. Teeth — in an uninterrupted crescentic band across the palate. jF//is— dorsal as high as the^ body 

 below it, its spine very finely serrated posteriorly or entire, and 4/9 of the length of head : length of base 

 of adipose dorsal exceeds that of the rayed fin or of the interspace between the two. Pectoral spine strong, as 

 long as the head excluding the snout, and having from ten to fourteen strong denticulations internally. 

 Upper caudal lobe the longer. An anal papilla before the fin. Colours -haden or brown superiorly, lighter
