Habit. — Sea coast of Pinang. 

 Canton. 



Total length : 6 inch. 



The length of the head is a little more than f of the total length 9 

 the height slightly exceeds the breadth and equals half the length. The 

 vertical diameter at the anterior dorsal is \ of the total length. The 

 muzzle is rounded, the gape wide, the angle of the mouth is opposite the 

 posterior angle of the orbit. The eyes are contiguous, situated a little 

 behind the second fifth of the head ; upper eyelid with tubercles ; the 

 lower membranous, hemi-transparent. The upper jaw has on each side of 

 the symphysis three conical teeth, distant, and longer than the rest, of 

 which there are upwards of 30 very minute, and distant, on each side. 

 On the upper lip behind the canines appears a small flattened lobe. 

 Each side of the lower jaw carries 30 to 34 horizontal, closely set teeth, 

 which are long, almost setaceous, obliquely truncated at the apex. On 

 each side of the symphysis, on a more inward level than the others, is 

 a stronger, conical, vertical tooth. The tongue is small, rounded, 

 fleshy, and fixed to the floor of the cavity, and as well as the latter 

 inky. The anterior dorsal commences a little behind the root of the 

 pectoral ; the four posterior rays are filamentous : the third, the long- 

 est, is little less than \ of the total length ; the fifth, a little shorter 

 than the first, equals about one half of the third ; the membrane 

 extends close to the posterior dorsal ; the base of this fin equals 

 the greatest vertical diameter of the body. The posterior dorsal 

 slightly increases in height towards the 21st ray, which measures about 

 § of the greatest vertical diameter of the body ; the base of the fin is 

 Z\ times its height. The caudal is a little pointed, the length little 

 less than \ of the total. The anal commences opposite the second 

 branched ray of the posterior dorsal, the tract of which it follows, but 

 its height is less by one third ; the 23rd ray is the longest and less 

 than one half of the greatest diameter of the body. The ventrals are 

 infundibuliform, their length is about i of the total. Two thirds of 

 the pectorals are covered with scales ; their length is about f of the 

 total ; the naked portion of this fin is oval. The scales resemble those 

 of B. boddaertit increasing in size on the abdomen and posterior part 

 of the body, deeply imbedded in the integuments, which are covered 

 with numerous papillae. Single individuals were observed at Pinang.
