 lateral line, there is a round spot of deep black, 

 and a dull band of the same colour bounds the soft 

 extremity of the anal fin. 



This last fish, in many parts of its form, and in 

 its bright colour, resembles the Serrani, and it is 

 possible that it may stand described under that 

 generic appellation ; at the same time, our drawing 

 and short notes agree with the characters we have 

 printed from the Brazilian Fishes. 



The second form of Cychla, and that to which 

 we feel inclined to restrict the appellation, is repre- 

 sented by the C. monoculus, Spix, tab. Ixiii., by 

 those described in the second volume of Humboldt's 

 Zoological Rescearches, and by the C. ocellaris of 

 Schneider. It belongs to the Labrince. The fishes 

 composing it are all brightly and gaily coloured, and 

 are remarkable for their very decided banded and 

 ocellated markings, which also prevail in all the 

 species of which we now possess drawings. This 

 genus of Bloch and Cuvier, to which most modern 

 Ichthyologists refer these fishes, is not recognised by 

 Valenciennes, who seems to have distributed them 

 through other groups. In the Histoire Naturelle des 

 Poissons, he says, " Mais le genre Cychla, compose 

 d'abord d'une maniere trop vague a ete reduit par 

 nous, a des especes de la famille des Labres." With- 

 out having examined specimens, we should not like
