The head is elongate ; its length is equal to the 

 body's greatest height. Its upper profile is in the 

 form of a regular shallow arch. The snout is poin- 

 ted. The space from the snout-extremity to the eye's, 

 anterior margin is about three times as great as the 

 diameter~of the eye. 



The eye has a circular contour ; its upper margin 

 does not reach up to the upper profile of the head. 



The posterior nostril is situated a little in front 

 of the eye. The anterior is distant from the snout- 

 extremity four times as far as from the posterior 

 nostril. The cleft of the mouth is horizontal, reaching 

 back to the middle of the lower margin of the eye. 



The mandible projects a little beyond the upper 

 jaw; its lower profile is straight, retreating with a 

 slightly prominent^ angle. Teeth in both jaws. Pec- 

 toral fins none. The vertical fins show but slight 

 development; the dorsal fin has its origin a little in 

 front of the vent; the caudal fin is pointed. 



The vent is in front of the body's middle, approxi- 

 mately at one third of the length from the fore part. 



There are some series of closely packed pig- 

 mentary spots grouped along the sides of the body 

 immediately above the alimentary canal. There are 

 moreover a few scattered ones on the head in the 

 region of the gill-openings and the snout-extremity. 



In the collection there is one example of this 

 species, obtained by Captain von Scheele in 1885 in 

 the Bali Straits. Its measurements are as follows: 



Length of body 44 mm 



Greatest height of body. 4 „
