D. 2.13 15; A. 2.14 16; P. 1.9 10; V. 1.5; L.I. 5860. 



Compressed, the breadth of the body going 1.3 1.5 in its 

 height. Height 11 16, 12 18 in length with caudal. Head 

 from tip of upper jaw to branchial opening 3.1 3.5 in trunk. 

 Entire head 2.3 2.6, 2.7 3.1 in length with caudal. Length 

 of lower jaw beyond extremity of upper jaw 3.5 4.5 in length, 

 45 in length with caudal. Eye 1.5 1.8 in postorbital part 

 of head and equal to interorbital space. Praeorbital much 

 longer than high, its length equal to diameter of eye. Trian- 

 gular part of upper jaw, formed by intermaxillaries, somewhat 

 broader than long. Teeth small, in narrow bands in both jaws. 

 Origin of anal below or slightly behind that of dorsal, which 

 is separated by 39 41 scales from occiput and by 6 7 scales 

 from lateral line. Dorsal and anal concave, the anterior rays 

 the longer. Base of dorsal equal to or a little longer than 

 that of anal. Pectorals conspicuously shorter than head without 

 snout. Ventrals about 2 / 3 length of pectorals, their first ray 

 the longest. Origin of ventrals midway between head and base 

 of caudal. Caudal forked. Colour of preserved specimens yellow- 

 ish, darker above, each scale of the back having a dark brown 

 spot. A silvery lateral band, broadest below origin of dorsal, 

 bordered above by a more or less conspicuous blackish blue 

 line. Fins more or less dusky, especially the dorsal and caudal. 

 Length 220 mm. 



Habitat: Bali; Sumba ! ; Flores ! ; Kajoa!; between Gebe 

 and Fau ! ; Ceram ! ; Binongka!; Tiur!. Funafuti. 



In sea. 



Note. Very young specimens are characterized by having 

 a row of about 15 partly alternating black points on each side 

 of the back, between the end of the dorsal and the head 

 (see MAX WEBER 1. c.). 



Besides these specimens we have 7 specimens from Pulu 

 Babi, West Coast of Sumatra, which are less compressed 

 (breadth i.i 1.2 in height), have a comparatively somewhat 

 larger eye and have the origin of ventrals conspicuously 

 nearer to base of caudal than to head. The triangular part 

 of the upper jaw is somewhat longer, nearly as long as broad. 

 In every other point they are like H. balinensis. 



We propose to call them H. balinensis var. occidentalis.
