twelth volume of the Linnezn transactions by Captain Carmichael, under the name 
of Callionymus diacanthus, for it was easy to perceive that it was not a Callionymus. 
We have been fortunate enough to find it among the species collected at Valparaiso, 
from Chili, by M. d’Orbigny. It is a particular genus, near the Trachinus, having 
like them teeth as the pile on velvet in the jaws, in the palate and on the vomer, 
but is distinguished not only from the Trachinus, but also from all the other jugular 
Percoides, the Percophis excepted, by the seven rays of its branchiostegal membrane. 
The colour appears to have been blackish. The length of the individual is eight 
inches, the caudal not included. Captain Carmichael says his fish had the body olive 
colour marbled with greenish spots, and marked with white dots, and the iris of the 
eye brown. On his figure (pl. 26. vol. 12.) of tbe Linnzn transactions, twenty two 
rays are marked to the second dorsal; but in the text the author only enumerates 
twenty rays. The characters of the penultimate and antepenultimate rays pro- 
longed from the anal, is well expressed in the figure that we quote. 
* Cuvier found in the lot of fishes brought to Europe by Messrs. Quoy and Gaimard 
three small Percoides with jugular ventrals, originally from the soft waters of Van 
Dieman’s land, which are all three of the same species, but which must become the 
type of a new genus, near that of the Percophis. (p. 94.) The name of Aphritis 
has been given to the genus, and that of Aphritis Urvillii to the species figured by 
us, 
This species has acylindric body, of which the diameter, in front of the anus, is 
the sixth of the total length ; the colour is reddish, shaded, and marbled with greenish 
brown on the back. The fins are transparent. On the two dorsals, and on the cau- 
dal, we see two or three rows of small red dots. ; 
+ This fish forms a new genus of the family of Percoides wth six branchial rays, 
and free rays to the pectorals, consequently near the Cirrhites ; but itis easily distin- 
guished from them, by the form of the teeth, which resemble those of the Crenidens 
Forsk., of the family of Sparoides. We give to this genus, the name of Aplodac- 
tylus, to recall the simple form of some of the pectoral rays, and to the species we 
have figured that of Aplodactylus punctatus. Its height measures the fourth of its 
total length. The thickness is contained twice and a half in the height; the snout 
is obtuse and rounded. The line of the profile of the head, ascends by an arched 
curve, sustained even to the occiput, from whence it rises, and ascends obliquely, 
following an almost straight direction, even to the base of the dorsal. The curve of 
the back is slight; that of the belly is rather more so. The height of the tail is 
only the third of that of the body, measured perpendicularly from the ventrals. 
The head is short, and swelled in front. It has its length contained four times and 
four-fifths in that of the body. Its height from the neck downward, is a fifth less 
than its length. The eyes, of moderate size, are on the first half of the head, and 
placed in the upper part of the cheek, without, however, the circle of the orbit 
encroaching on the line of the profile. 
The scales are very small; there are more than a hundred and twenty between 
the gill and the caudal—seen separately, and through a magnifying glass, each of 
them presents a square surface, finely striated on the sides, and of which the radical 
edge is finely indented. The lateral line is traced beneath the third of the height, 
and forms slight undulations. Ona white ground, brownish towards the back, the 
body is spotted with an infinite number of little blackish dots, equally spread over the 
fins, which are darker than those on the back, 
M. Gay has likewise observed this fish ; for we have found a coloured drawing of 
it among the drawings of this naturalist, which leads us to hope that the species is 
not_very r.re, and that wemay receive other individuals.
