"The body is strongly compressed, moderately elongate and 

 low; its greatest height, contained about eleven times in its 

 length is situated rather behind the middle. It gradually dimi- 

 nishes in height from that point towards both head and tail 

 in approximately equal degrees. 



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 pointed. 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. Pectoral 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 ot the body's "middle, approximately 

 at one third of the length from the fore part. 



There are some series of closely packed pigmentary 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 gillopenings 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 als follows: 



i) As STROMMAN'S publication is rather rare, we thought it convenient for 

 those who use our book, to reprint his description.
