500 A COLLECTION OF FISHES FROM SUMATRA. 



spine smooth on outer surface, and equal to about two-thirds length of fin. 

 "Ventral inserted well behind origin of dorsal and reaching past origin of anal. 

 Caudal elongate and rounded. Anal papilla long. 



Color in arrack dark blackish-olive above, lower surface brown. Vertical fins 

 blackish-olive. Pectoral and ventral brownish, darker above. Indistinct traces 

 of vertical series of pale dots on sides of back. Barbels blackish. Peritoneum 

 whitish. 



Length 11|- inches. 



Type No. 27,280, A. N. S. P. Padang. 



This .fish, originally described by Valenciennes, is said to have the head, 

 measured to end of occipitial process, 4|- in total length of body, including caudal, 

 and fins with 67 dorsal and 48 anal rays. The Formosan fish figured by Drs. 

 Jordan and Evermann as Chlarias fuscus (Lacepede) is certainly diflferent. A com- 

 parison of the type with four cotypes with same data, and measuring 1\ to 10^ 

 inches, shows dorsal ranging from 60 to 63 and anal 50 or 51 rays. It is, however, 

 in the more slender or elongate body that olivaceus differs from related species. 

 Space between occiput and dorsal was found to be 2|-, 2-|, 2-1-, 2|- and 2|- in head, 

 measured from former point to tip of snout. Gill-rakers 5 + 4 on first arch of one 

 of cotypes. Possibly records for Chlarias liacanthus in Sumatra should go with 

 this species.
