Family MUR/ENEMOCIDiE. P>ls. 

 Muraenesox cinereus (Forskai). 



Color drab-brown above, paler below. I'he lateral line very distinct; 

 fins yellowish, the tips of dorsal and anal black, these fins becoming 

 entirely dusky near and at end of caudal. Snout long; teeth large, the

 556 millimeters. 



A fish of considerable food importance in Borneo; also recorded from

Family CYPEINIDJ5. Minnows. 

 Barbus elongatus Seale, sp. nov. Plate II, fig. 1. 



Head 4: depth 3.1; dorsal 13; anal 8; scales r,-'ri (to end of caudal 

 verteliia)— t; the lateral line cnr\es down to a little below the median 

 line of side-;, then up to middle of base of caudal; eye 3.75 in head; 

 snout 4; interorbital 2.70; ma.xillary scarcely reaching to anterior margin 

 of eye; two maxillary barbules on each side, the longest 2 in head; 

 pectorals about equal to head; ventrals 1.15 in head. No teeth except 

 pharyngeals which are 4-3-2, the larger ones slightly hooked and each 

 with a small shoulder. 



Body oblong, compressed, the outline between origin of dorsal and 

 tip of snout somewhat gibbous and with a concave ai-ea. above the eye; 

 caudal peduncle rather long and slim, its depth being 1.75 in its length; 

 origin of dorsal midway between tip of snout and end of caudal vertebra, 

 the second large ray enlarged and serrated on its upper two-thirds ; the 

 enlarged hard portion equal to distance from middle of eye to end of 

 opercles; origin of anal much nearer origin of ventrals than the end of 

 caudal vertebra, longest anal ray 1.70 in head; origin of ventrals midway 

 between origin of anal and posterior margin of opercl es ; caudal deeply 

 emarginate, its length greater than head. Gill openings restricted, 

 ending on a line with angle of preopercle. Gill rakers small, rather 

 sharp pointed, about 9 on lower arch. 



Body entirely covered with large smooth scales which have 4 to M 

 striate lines; tubes of lateral line unbranched ; ventral with axillary 

 scale ; scaly sheaths to dorsal and anal ; head entirely naked. 



Color silvery with a slight shade of yellowish ; four round black spots 

 on middle line of sides, one at base of caudal, one at origin of lateral 

 line, two on the lateral line near the middle. A black spot at origin of 

 anal. TJpjjcr rays of doi-sal, anal, and caudal, dusky. 



This species is nearly related to Barivs ivis Seale from Balabac Island, 

 from which it is ^easily distinguished by its more elongated form, long 

 caudal peduncle, the more anterior location of the anal, and the less 

 distance between the anal and ventrals. This spcries also has a larger e3'e.
