SILUKID.E. 157 



Length of head 5 J, of caudal fin 4, height of body 5 in the total 

 leugth. Eyes diameter 3 to 3| in the length of head, about one 

 diameter from end oE snout and also apart. Profile from snout to 

 dorsal fin rather elevated. Greatest width of the head equal to 

 its length excluding the snout; upper jaw slightly the longer. 

 Summit of the head rough ; median longitudinal groove extending 

 nearly to the base of the occipital process, which 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 maudibular the middle of the pectoral, whilst the inner are 

 rather shorter. Teeth in an uninterrupted crescentic baud across 

 the palate. Fins dorsal spine of moderate strength, as long as 

 the head excluding the snout, two or three teeth anteriorly, serrated 

 posteriorly ; the length of the base of the adipose dorsal equal to 

 that of the rayed fin, but about one fourth less than the interspace 

 between the two fins. Pectoral spine stronger than the dorsal, as 

 long as the head behind the angle of the mouth, and with about 

 ten very strong teeth internally. Caudal deeply forked, the upper 

 lobe being the longer. Colour silvery, lightest beneath, a dark spot 

 at the commencement of the base of the dorsal fin, which is also 

 black-tipped, a darkish band along the middle of the fin. 



Hob. Malabar coast and the Coimbatore district. This species 

 attains 5 or 6 inches in length.

Length of head 4| to 5, of caudal fin 5|, height of body 5 in the 

 total length. Eyes diameter 4 to 6 in the length of head, 1 to 

 2 diameters from end of snout, and 1| to 2 apart. The greatest 

 width of the head equal to its length excluding the snout or behind 

 the angle of the mouth, and very little more than its height ; in 

 some specimens there is a considerable rise to base of the first 

 dorsal fin. Upper surface of the head roughened in tubercles 

 hardly forming lines, median longitudinal groove reaching to mid- 

 way behind the hind edge of the eye and the base of the occipital 

 process, which is rough, three times as long as wide at its base, and 

 a short (if any) interspace exists 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 in raised lines. Barbels the maxillary reach the ven- 

 trals, the nasal the opercle, the external mandibular the first third 

 of the pectoral spine, whilst the internal are shorter. Teeth iu
