belonging to the Genus Trisotropis. 305 



After describing this species in my Memorias, I made it, in my 

 Synopsis, p. 282, a variety of the. Trisotropis cardinalis, be- 

 cause I believed that the round spots were peculiar to the adults, 

 and that at the same time the red color disappeared ; but I now 

 believe that our fishermen are right in considering it a distinct 

 species.

The whole body covered with large irregularly quadrilateral 

 spots of a violet brown, separated by pale rivulations which run 

 together under the stomach. The fins are brown, and the mar- 

 gin of the pectorals, not at all or else a little bordered with 

 orange, without definite limits. In this the species chiefly dif- 

 fers from T. petrosus. I sent a specimen to the Cambridge 

 Museum, 1250 mm - long, weighing 66 pounds. In the young 

 specimens* the form and size of the spots vary greatly, which 

 caused me to mistake varieties for species. The preopercle is 

 rounded. Its popular name is aguaji. 



See for comparison the notes on my fifth species, the Bonaci 

 arara of Parra. 



I at first believed that the Serranus undulosus, Val., Poiss. ii. 

 295, from Brazil, might be the same as the Cuban species; but 

 having received it from Paris through M. Aug. Dume'ri], 8 

 inches long, I saw that the caudal was slightly rounded, which 

 is not a difference due to ago, as I found on comparing it with 

 young specimens observed in Havana. The brown undulations, 

 oblique on the cheeks, horizontal on the body, the yellow base 

 of the anal and of the soft dorsal, would bring the Brazilian 

 specimen near to my Trisotrojns aguaji. It is probable that the 

 Serranus undulosus, attributed to Valenciennes by Dr. Giinther,
