tion of Sloane in their works on Jamaica. It is very evident from 
Sloane’s figure that the species he had in view was the Achirus maculipin- 
nis. So far as we know, but two species of Achirus (inscriptus and ma- 
culipinnis) are found in the waters of the Antilles. There seems to be, 
then, no doubt that the maculipinnis of Agassiz is the original Plewro- 
nectes lineatus of Linnzus. If it be so, it must stand as Achirus line- 
atus. 
The Pleuronectes lineatus of the twelfth edition of the Systema Nature 
is described from a fish sent from Charleston by Dr. Garden. This is 
Achirus fasciatus. 
We have placed the Florida species, comifer and brachialis, in the sy- 
nonymy of lineatus. They differ from the latter only in the slightly 
smaller numbers of the scales and fin-rays. 
The following table shows our count of a number of specimens from 
different localities :

It is evident from this table that neither the fin-rays nor the scales 
form characters by which the subspecies can be absolutely distinguished. 
It is evident also, from the examination of large series of specimens, 
that the coloration is subject to very great variations—as great as in 
Achirus fasciatus. In some of these the caudal is dark and immaculate, 
in others pale and usually profusely spotted. In some the ground color 
is nearly plain blackish, in others it is pale, usually with narrow dark 
cross-bands, but sometimes closely spotted everywhere. 
The specimens examined by us are from Pensacola and Egmont Key 
(brachialis), Key West (comifer), Cienfuegos (Cuba, Poey), Coary, Teffy, 
Tapajos, Porto Alegre, Pernambuco, Cannarivieras, Manacapuru, Porto 
do Moz, Rio Grande do Sul, Rio Janeiro, San Matheo, Rosario, Itaba- 
puana, Obidos, Xingu, Gurupa, Jutaby, Curuga, Para, Bahia, Santa- 
rem, Ica, Fonteboa, San Paolo, Rio Trom sit Sambaia, Manes, Javary, 
and Tabatinga. 
The species would appear to be one of the commonest in Brazil.
