thirteen in the second, and fourteen in that behind the 

 vent. 



This comes nearest the G. schlosseri of La Cepede, but dif- 

 fers somewhat in the number of rajs in the fins ; and in other 

 respects his description is so short, that no one can be certain 

 whether or not this and his fish are of the same species. 



With respect to colour, the black belts, very conspicuous on 

 the fourth species, on this little fish are scarcely observable ; 

 and it has very few white or blue spots on its body, nor any 

 tubercles on its scales. The first dorsal fin is black, with a 

 transparent edge ; the second is transparent, with two black 

 longitudinal stripes. The pectoral fins are entirely transpa- 

 rent. 



The under jaw, which is covered by a lip, has no protuber- 

 ance in its centre, and contains a few erect teeth, while there 

 are many in the upper jaw. The upper Up is double, the 

 outer one having a sliarp process on each side, while the inner 

 consists of two lobes. The tongue and palate are white. Each 

 membrane of the gill-covers contains two rays. 



There are no lateral lines, and all the scales are imbricated. 



The first back fin slopes gradually down from the first ray, 

 which is the longest ; but, like the others, scarcely exceeds the 

 membrane in length. The first nine rays of the second fin are 

 undivided, the tenth is bifid, and the three last are branched. 

 In each of the pectoral fins .are thirteen rays. The vetitral fin 

 is almost plain. The rays of the anal fin are undivided. The 

 tail fin has seventeen rays, of which two or three below, and 

 five or six above, are very short.
