third spine strongly ossified, nearly as long as head. Pectorals 

 and ventrals subequal. Ventrals separated by 5 or 5^ scales 

 from lateral line, the outer rays prolonged, reaching on anal. 

 Pectorals slightly longer than head without snout, reaching on 

 ventrals or nearly so. Caudal deeply emarginate, the lobes 

 strongly diverging, about equal to head. Least height of caudal 

 peduncle 1.8 in head, somewhat shorter than its length, sur- 

 rounded by 20 scales. Most scales only with growth-lines, some 

 of them with fine undulating lines at the hindborder. Tubes 

 of lateral line short, mostly directed downwards. Silvery, 

 upper half brown. A blackish band behind operculum, beginning 

 at the nape. Vertical fins blackish. Length 277 mm. [Type of 

 the species in the zoological Museum of Amsterdam]. 



Habitat: Borneo (Bunut !) ; collected by Dr. H. A. LORENTZ 

 and named after his son.

 Compressed, very elevated, dorsal profile strongly ascending 



from front to dorsal and somewhat arched. Height 2,6, 3.3 in 

 length with caudal. Head 3.9, 5 in length with caudal. Eye 4.3, 

 surrounded by a gelatinous membrane, situated for its greater 

 part in the anterior half of the head, slightly below the upper 

 profile, about 2 / 3 of length of snout and nearly twice in flat 

 interorbital space. Mouth nearly terminal; no barbels. Origin 

 of dorsal opposite to nth scale of lateral line and to that of 

 ventrals and to the middle of a line, connecting end of snout 

 and base of caudal; separated by about 13 scales from occiput. 

 Dorsal with a scaly sheath, deeply emarginate, the fourth 

 spine, which is strongly ossified and strongly denticulated and 

 the first divided ray are much prolonged and J / 4 longer than the 

 head. Anal with a scaly sheath, deeply emarginate, the first 

 divided ray and the ossified third spine, which is very strong, 

 prolonged, about 4 / 5 length of head. Ventrals somewhat longer 

 than pectorals, nearly reaching anal, separated by 4 scales 

 from lateral line. Pectorals about 3 / 4 length of head. Caudal
