shorter than, the eye, in a very narrow band. The maxillary barbels 

 reach to the end of the humeral spine and are lined with a narrow 

 membrane interiorly. Mandibulary barbels reaching to the root 

 o£ the pectoral, provided with numerous long fringes. Nuchal 

 carapace teetiform, obtusely rounded behind, its end reaching to 

 below the first soft dorsal ray. Humeral spine not quite extending 

 so far backward, much longer than high, with its upper margin 

 deeply excised, terminating in a sharp point. 



Adipose fin rather long, the interspace between it and the 

 dorsal being less than the base of the latter. Dorsal spine ser- 

 rated anteriorly, shorter than the pectoral spine, which is strongly 

 serrated along both edges and equal to the distance of the foremost 

 part of the soft part of the trunk from the snout. Dorsal and 

 pectoral spines and the caudal lobes produced into filaments. 

 Coloration uniform.
