for more than a score of years ago, One of the genera has had a singular 
history, which may be detailed more at length hereafter. Suffice it now 
to state that one species was originally described as a Oentrolophus, and 
subsequently differentiated as a peculiar generic type under the names 
Letrus and Mupus, while another closely related was originally intro- 
duced as a Ooryphena, again as a Trachynotus, and afterwards distin- 
guished as a new genus Palinurus, near Trachynotus. The name Pali- 
nurichthys, was substituted for it Nov., 1859, by Bleeker and about the same 
time,* in Jan., 1860 (Proc, Acad. Nat. Sci., Phila., 1860, p. 20), Gill also in- 
dependently proposed the name Palinurichthys asa substitute for Palinurus. 
In the “Catalogue of Fishes of the Eastern Coast of North America,”’ pub- 
lished in Feb., 1861 (p. 84), it was referred to the sub-family Centrolo- 
phine. In critical remarks on Dr. Giinther’s composition of the Scom- 
broid families (‘‘On the Limits and Arrangement of the Family of Scom- 
broids’’), published in March, 1862 (Proc. Acad. Nat. Sci. Phila., 1862, 
p. 127), it was claimed that “nearly allied to the preceding [Stromateins ] 
are the Centrolophine, with the genera Ovntrolophus Lac., Leirus Lowe, and 
Palinurichthys Gill, Blkr. (=Pammelas Gthr.). Closely connected to the 
Jentrolophine are the genera Schedophilus Cocco and Hoplocoryphis Gill 
(type Schedophilus maculatus Gthr.).’? A few lines further it was again 
remarked that among the forms that should be withdrawn from the Caran- 
gide was ‘‘ Pammelas Gthr., which is nearly allied to Centrolophus.’’ 
Finally, in Gill’s new ‘Catalogue of the Fishes of the Eastern Coast of 
North America’’ (1872, p. 9 ), Palinurichthys was enumerated under the 
family ‘‘Stromateidm’’ and the subfamily ‘‘Centrolophine.’’ Notwith- 
Standing these explicit statements the genus has been retained by Dr, 
Giinther and Dr. Day next to Zrachynotus, with which it has no affinity 
whatever. Its anatomy conclusively shows that the view, originally 
formed by the author from a consideration of its exterior, is perfectly cor- 
rect. It has the number of vertebra, epibranchial processes, &ec., of Cen- 
trolophus, and in fact is scarcely, if at all, distinguishable from GC, ovalis 
of European authors.
