Compressed, the breadth of the body going 1.4 1.5 in its 

 height. Height 5 5.3, 6.5 7 in length with caudal. Head 

 4 4.3, 5 5.5 in length with caudal. Eye 2.6 to nearly 3 in 

 head, scarcely less than postorbital part of head, which is 

 equal to interorbital space. Snout about 3 / 4 of eye. Teeth com- 

 paratively well developed, simple, in a few rows in the jaws; 

 a few teeth on each side on the palatines. Origin of anal 

 opposite to 6*h ray of dorsal. Origin of dorsal separated by 

 about 30 scales from occiput, its distance from first rudimentary 

 rays of caudal equal to head or only scarcely longer than 

 head. Pectorals reaching to posterior part of dorsal or farther. 

 Ventrals longer than head or scarcely so, reaching to middle 

 of anal or not so far, their origin about midway between base 

 .of caudal and hindmargin of praeoperculum. Caudal deeply 

 forked. Pectorals blackish, with a narrow hyaline hindborder 

 and an indication of a hyaline transverse band and provided 

 with more or less numerous round black spots. Other fins 

 hyaline, caudal dusky. Ventrals and dorsal sometimes with a 

 black spot posteriorly. Length 350 mm. 



Habitat: Pulu Weh!; Java Sea!; Celebes (Menado, Goron- 

 talo!); between Buton and Buru !. -- Seas of India, Tahiti.

Height somewhat more than 5, 6 } / 2 7 in length with caudal. 

 Head 4 or nearly 4, 5 or a little more than 5 in length with 

 caudal. Eye 3, somewhat more or less than postorbital part 

 of head and equal to or somewhat less than flat interorbital 

 space. Snout shorter than eye. Teeth minute, apparently absent 

 from palate. A broad ribbon-like barbel at symphysis of lower 

 jaw, consisting of a white median ridge which bears a deep 

 black lamella at each side and reaches somewhat farther than 

 the base of pectorals or almost to the ventrals. Origin of anal 

 about opposite to 4th__6th dorsal ray. Origin of dorsal separated 

 b y 2 732 scales from occiput. Length of anal 2 / 3 of that of 

 dorsal or a little longer. Pectorals reaching to end of dorsal 

 or not so far. Ventrals much longer than head, reaching to
