Height 3 — 3.7, 4 — 4.8 in length with caudal. Head 4.1 — 4.5, 

 5.2 to nearly 6 in length with caudal. Eye 3- — 4, shorter, even 

 '/g shorter than snout, twice or less than twice in interorbital 

 space, somewhat behind middle of length of head. Snout bluntly 

 rounded, prominent, in front with a large median pore or 

 tubercle and a lateral^ smaller one on each side, the three 

 being placed in a more or less horizontal series; there may 

 be besides other smaller pores or they may be absent, espe- 

 cially so in small specimens. Maxillary barbels about as long 

 as the eye, the rostral ones smaller. Origin of dorsal opposite 

 to 8th or 9th scale of lateral line, separated by 10 — 12 scales 

 from occiput. Anterior rays of dorsal more or less prolonged, 

 their height equal to or more than length of head. Anal with 

 the anterior rays prolonged, shorter than head, opposite to 

 2ist to 23rd scale of lateral line and about 2 scales behind end 

 of dorsal. Ventrals sUghtly longer than pectorals, reaching anus 

 or not so far, or even to anal. Their origin opposite to nth 

 or 1 2th scale of lateral line and to 2nd or 3rd branched dorsal 

 ray, separated by 4 to 4Y2 scales from lateral line. Pectorals 

 somewhat shorter than head. Caudal deeply emarginate, the 

 lobes pointed, their length about equal to or much more than 

 height of body. Least height of caudal peduncle 1.7 or some- 

 what more in length of head, 1.2 — 1.4 in its own length, 

 surrounded by 16 scales. Colour of preserved specimens 

 yellowish, back darker. Generally a black band along the 

 lateral line, which may run to the end of the middle caudal 

 rays. In young specimens there may be dark spots on the 

 scales, sometimes forming rows. Sometimes one or two series 

 of dark spots on the dorsal. Length 260 mm.
