THE BRAZILIAN RYPTICUS. 161 



The second species, closely resembling the first, 

 represented on the accompanying Plate XXX, 

 is found in the Brazilian Seas, and is of a greyish 

 sandy colour, spotted over with small darker 

 coloured specks. 



This is the last form among the percoid fishes 

 which we shall be able to illustrate in the present 

 volume ; and upon inspecting the table of genera, 

 (page 89,) it will be perceived that nineteen 

 additional forms remain, to which must be added 

 other four, which Cuvier found it necessary to 

 introduce after the construction of his table, 

 leaving twenty-three, or nearly the half of this 

 great family, unnoticed. In order to follow out 

 our plan, and make each volume as complete as 

 possible by itself, independent of its predecessors 

 or followers, we shall shortly notice the remaining 

 divisions of the family, and add one or two 

 species which have been found in a fossil state. 

 We shall proceed in the order of the table : 



The genus Cirrhites of Commerson, follows our 

 last. The species approach nearest to Mespprion, 

 have the preopercle toothed on its rising edges, 

 and the opercle terminated by a flat angle ; but 

 the character which distinguishes them is in the 

 structure of the pectoral fins, which have the six 

 or seven lower rays of each fin strong and 

 lengthened beyond the others, without membrane*
