thaiftip of snout and level with upper margin of eye. Preorbital not 

 distinct, and together with cheek covered with skin. Interorbital 

 space elevated a little convexly and flattened medianly. 



Gill-opening lateral, extending forward about opposite posterior 

 margin of preopercle. Rakers in form of a low fringe of fine or minute 

 filame2its. Filaments long, about equal to orbit. No pseudobranchise. 

 Width of isthmus where gill-membranes join about equal to orbit. 



Scales large, cycloid, and well exposed, also of more or less even size. 

 Scales on breast small, especially anteriorly. Small scales along bases 

 of dorsal and anal. A pointed scaly ventral flap in axil of fin about f 

 its length. Head and fins naked, except base of caudal. Lateral line 

 of short exposed single tubes, and continuous even on base of caudal. 



Origin of dorsal about opposite tip of depressed pectoral or a little be- 

 fore origin of ventral, second simple ray highest, next three graduated 

 down, after which they are all more or less of one size. Anal beginning 

 a trifle before base of last dorsal ray, and second simple ray also longest. 

 Caudal forked, lobes rather pointed. Pectoral small, and inserted low. 

 Ventral not quite reaching vent or about | of space to anal. 



Color in alcohol dull olivaceous-brown, paler below and on sides of 

 head. Fins pale brownish, dorsal and caudal scarcely darker. Each 

 series of scales marked by a bar, making about ten longitudinal dark 

 lines or bands less in width than pupil of eye, and dusky or most dis- 

 tinct above lateral line. Iris olivaceous, pupil slaty. Peritoneum sil- 

 very. Length 9 inches. 



Type No. 2,392, W. I. A. P. Baram river, Borneo. 1897. Mr. 

 Alfred C. Harrison, Jr., and Dr. H. M. Hiller. Also No. 13,897, W. L 

 A. P. Paratype. Same data. 



This species is close to Osteochilus kaho.janensis (Bleeker), w^hich has 

 been reported from the Baram river by Dr. Steindachner, but differs 

 apparently in the distinct longitudinal narrow brown stripes. My 

 examples also have no blue spot on the shoulder-girdle, though in alco- 

 hol the other color markings are fairly distinct. 



(Named for :\Ir. Alfred C. Harrison, Jr., of Philadelphia, explorer 

 of Borneo and Sumatra, wdio collected the type.)
