170 BLACK-BANDED POMOTIS. 



as a membrane, with a regularly rounded outline, 

 but with no jutting-out appendage as in P. vul- 

 garis ; the teeth, though fine, are represented of 

 considerable length, particularly on the upper jaw. 

 The length of the drawing is eight and a half, the 

 depth four inches ; the colour of the fish yellowish 

 umber-brown, interrupted by the broad black line 

 running along the centre of the body. The formula 

 of the fins is, 



D. 16/14 P. 13 V. 1/5 A. 8/12 C. 16 Br. 6. 



We possess a slight uncoloured sketch of another 

 fish, which appears nearer to Pomotis than the last ; ; 

 the teething is represented as more minute ; there 

 appears to be a slight auricle to the operculum, and 

 the anal fin has only three spiny rays. We give 

 an outline also to direct attention, with Mr. Schom- 

 burgk's short notes.
