Family MITE.ENESOCID^. Eel?. 

 Mursenesox cinereus (Forskal). 



Color drab-brown above, paler below. The 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 

 vomerine teeth with cusps on each side. ISTos. 2498, S500 ; length 490 to 

 .556 millimeters. 



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

 the Philippines. 



Family CYPEINID^E. Minnows. 



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



Head 4; depth 3.1;. dorsal 13; anal 8; scales 5-27 (to end of caudal 

 vertebra ) —J- ; the lateral line curves down to a little below the median 

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

 snout 4 ; interorbital 2.70 ; maxillary 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. jSTo teeth except 

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

 with a small shoulder. 



Bod)'^. oblong, compressed, the outline between origin of dorsal and 

 tip of snout somewhat gibbous and with a concave area above the eye; 

 caudal jjeduncle 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 opercles; caudal deeply 

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

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

 sharp pointed, about 9 on lower arch. 



Body entirely covered with large smooth scales which have 4 to 8 

 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. Upper rays of dorsal, anal, and caudal, dusky. 



This species is nearly related to Barhus 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 species also has a larger eye.
