The spinous dorsal is higher than in Lacepede and Russell's figure, and more resembles 

 Ruppell's, supposing that the membrane connecting the filamentous tips were more fully de- 

 veloped than it is shown to be in his figure. The central half of the fin is pure white.

I have had an opportunity of examining several specimens of this fish, viz. two brought 

 from the neighbourhood of Canton by Captain Dawkins and Sir Edward Belcher, and one 

 from the mouth of the Yan tze kiang by Sir Everard Home, besides some injured ones, all of 

 this species. They agree in the height of the body, which is greatest some way behind the 

 anus or nearly in the middle, being equal to one-fourteenth of the whole length ; the head* 



* Measured between the tip of the snout and end of gill-flap. As the lower jaw projects 

 the relative height of the head would be greater if the measurement were made from thence.
