reach their posterior border. lyips greatly swollen, corrugated ; 

 the upper lip with two short, stout digitiform processes in front ; the 

 lower lip interrupted in the middle line, with two or three longi- 

 tudinal ridges on either side ; mouth entirely ventral. Eye large 

 and prominent, situated dorsally near the middle of the length of 

 the head. 



Pectoral fins long and narrow, extending backwards about 

 I the distance between their own roots and those of the ventrals ; 

 ventrals narrow, extending backwards about the same distance 

 towards the anal; anal very short, a little deeper than the body ; 

 dorsal short, a little higher than the body, with its upper margin 

 nearly straight but sloping rapidly downwards and backwards ; 

 caudal very long, deeply emarginate, with the two halves pointed. 

 Scales small, absent from the head, hardly distinguishable on the 

 ventral surface of the body. Lateral line complete or nearly 

 so. 



Natural colouration. — Head and body dull golden yellow ; tip 

 of snout scarlet, numerous transverse bars of dark olive green, 

 usually broader than the interspaces, across the back ; a row of 

 large blackish spots or blotches ruiming along the mid-lateral line 

 and sometimes coalescing, extended on to the caudal fin. Fins 

 yellowish ; dorsal with an anterior scarlet border and caudal 

 broadly edged both above and below with the same colour. Red 

 markings evanescent. 



I have examined three specimens, the largest of which is 57 

 mm. long.

D. 9-10 (3/6-7). P. 15- V. 9- A. 6 (2/4). L. 1. 37- L. t. 6/31. 



A very distinct species, distinguished from Ps. balitora by the 

 possession of a pair of rostral barbels, by the fact that the dorsal 

 fin commences immediately above the ventrals, etc. 



Size small ; back moderately elevated ; ventral surface flat. 

 Total length 5 to 5^ times length of head, about 5 times length of 

 caudal fin and 4I to 5 times greatest depth of body. Eye 2f to 3^ 

 times in length of head. A pair of short barbels on the snout. 

 Upper lip long, fringed, plicate; lower lip bilobed, covered with 

 minute tubercles. Five outer pectoral rays undivided, flattened; 

 pectoral not nearly reaching root of ventral when adpressed ; ven- 

 tral a little longer than in P. balitora, with a small fleshy append- 

 age at its root in the male ; anterior border of dorsal imme- 

 diately above that of ventral ; the last undivided dorsal ray con- 

 siderably shorter than the first branched ray ; caudal bilobed, the 

 lobes rounded, lyateral line complete, running along caudal: 

 peduncle. The phar5mgeal bones very slender; their teeth long.
