Height 6*/ 3 7'/ 2 , greatest width 4 3 / 5 5, head about 5 in 

 the total length. Dorsal profile nearly straight. Nasal barbels 

 slightly longer than eye, maxillary barbels extending to front- 

 border of operculum, mandibulary barbels not reaching gill- 

 opening, mental barbels short. Occipital process triangular, 

 bluntly pointed, about i '/ 2 times longer than broad at its base. 

 Before its base a longitudinal groove, with a deep groove 

 at both sides, distinctly separated from the median fontanel. 

 Origine of dorsal above the middle of the pectorals, its height 

 about equal to postorbital part of head, its spine somewhat 

 longer. Anal of about the same height, ventrals reaching anal, 

 somewhat shorter than postorbital part of head. Pectorals as 

 long as head from anterior nostril, their spine of about the 

 same length, much longer than the dorsal spine. Caudal slightly 

 emarginate, about 2 / 3 of head. Least depth of caudal peduncle 

 more than thrice its length. Yellowish or brownish, with a 

 narrower or broader blackish band round the body below the 

 dorsal, which may extend to the hinderhalf of the tail (A. 

 zonatus}. In some specimens (A. pleurostigmd) a series of several 

 rounded yellow spots along the sides. Length 100 mm. [Speci- 

 mens of A. zonatus and A. pleurostigma of Bleeker's collection 

 in the Leyden Museum examined by us].
