Branchial openings reaching to below eye. A small pseudo- 

 branchia. Humerus forms above pectorals a triangle, with the 

 point directed backwards. Praeoperculum situated slightly before 

 occiput. Origin of dorsal behind half length of body and some- 

 what behind origin of ventrals. Height of dorsal anteriorly 

 equal to that of body, strongly descending backwards and 

 rounded. Anal in height and form equal to dorsal. Ventrals 

 reaching anus, pectorals shorter, not reaching ventrals. Caudal 

 semilunary incised. Scales weak, showing radii only in their 

 sessile part, on their free part strong concentric lines, in the 

 middle a retiform structure, they are smallest on back and 

 anterior part of belly. Pointed scale above ventrals absent. 

 Lateral line nearly straight, with simple tubes. Back and sides 

 brown. Abdomen silvery white, along the lateral line anteriorly 

 a diftuse dark band, dissolving on the tail in three to four 

 subsequent large black blotches. Dark brown clouds on back 

 and base of dorsal and caudal. Lower half of dorsal with an 

 oblique brown band, a longitudinal one in the middle of the 

 caudal. Length about 90 mm. [After Kner, not seen by us]. 



This species was placed by Kner with a query in the 

 genus Pachystonins. GUNTHER mentions it as a Barbns and 

 says: „said to be from Java, but evidently allied to the east- 

 asiatic types oi BarbtisT Kner himself gives as habitat: „von 

 Java?" It is therefore very doubtful if this is really a Javanese 

 species, as the localities given by Kner are often erroneous.

 far behind end of dorsal. Ventrals and pectorals horizontal ; 

 only one of the outer pectoral rays simple. Caudal deeply 

 emarginate. Scales small, multiradiate ; lateral line present.

 broadly united to isthmus. Pharyngeal teeth unknown.
