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 violetbrown, separated by palé 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 ñame is aguají.

 arara of Parra. 



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

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

 having received it from Paris through M. Aug. Duméril, 8 

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

 is not a diíference due to age, as I found on comparing it with 

 young specimens observed in Havana. The brown undulations, 

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

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

 specimen near to my Trisotropis aguají. It is probable that the 

 Serranus undulosus, attributed to Valenciennes by Dr. Günther,
