scale, situated in or (in adult examples) behind the middle of the 

 length of the head, shorter or much shorter than snout, I '/ 3 2 ! / 3 

 times in interorbital space. Snout obtuse, much projecting 

 beyond the lower jaw, with a very distinct lateral lobe; a deep 

 groove on each side of the snout, which is provided above 

 and on the sides with numerous conspicuous pores. Maxillary 

 and rostral barbels subequal, small, the latter often rudimentary. 

 Mouth broad ; lips thick, continuous, not fringed, with an inner 

 fold in their entire circumference, equally developed on the 

 lower and upper lips. Dorsal emarginate, its height I 1 ! / 4 in 

 height of body, its origin separated by 16 scales from occiput. 

 Anal somewhat or slightly emarginate, not much lower than 

 dorsal. Ventrals and pectorals subequal, 5 ! / 3 to more than 6 

 in total length; ventrals not reaching anal. Caudal deeply 

 incised, the lobes pointed, longer than head. Least height of 

 caudal peduncle, measured by us in a small specimen, 1.8 in 

 head, somewhat shorter than length of peduncle, surrounded 

 by 1 8 scales. Coloration uniform, in youth there seems to be 

 a diffuse black blotch on the base of caudal. [After BLEEKER 

 and GiiNTHER. Only a small example in bad state seen by us]. 

 Length 275 mm. and more.

 length with caudal. Head 5.2, 6.9 in length with caudal. Eye 

 4, much shorter than snout, which is not much shorter than 

 the postorbital part of the head, somewhat more than twice

 to a short space beyond the corner of the mouth. Only a 

 pair of rostral barbels developed, their length about equal to 

 half diameter of eye. Origin of dorsal opposite to io th or nth 

 scale of lateral line and to the end of the second ! /s of a line
