whole of this fish is silvered; its back, tinted with grey brown, has brownish oblique 
lines, which descend in advancing towards the tail; on the flank these lines become 
longitudinal ; a little lower down they fade away ; and there are none on the lower 
part. The membrane of the first dorsal is blackish, with a white triangular spot at 
its base in each interval of the rays. The individual from which our drawing was 
taken, is seven to eight inches in length. it was M. Delalande who brought the 
first Larimes to Europe from Brazils, but there have been recently several received 
from St. Domingo through M. Ricord. It is called in that island silver-fish, on account 
of its colour, which in its fresh state is as brilliant (according to our traveller) as that 
of the purest mercury. M. Ricord adds that this fish is a foot long, that its flesh is 
bad, and only eaten by the poor. 
* The name of Lepipterus designates Sciznoides with two dorsals, teeth as the 
pile on velvet, prolonged snout, the front of the cranium rather concaye, and the 
vertical fins of which, are very scaly. We know only one—the Lepipterus Fran- 
cisci. This fish seems also to resemble the Corvina, by its soft teeth and its large 
anal spine: but it is a Corvina with the front of the cranium lengthened, and even 
a little concave; besides, the scales which cover its second dorsal, and its caudal, 
approximates it to the Eques and to the Polynemes. Its general appearance is 
similar to the Otolithus twroe, Cuv.; but, with a little attention, it is easily distin- 
guished from it. It is a fish altogether of an elongated form, head long, front of 
the cranium rather concave. Its height is only the sixth cf its length, and its head 
is almost the fourth; but its head is a thirdless in height than in length. The under 
orbital, covered by scales, which do not permit us to distinguish it from the cheek, 
forms a border, under which the upper jaw retires, as in the Ombrine; the mouth is 
very small,and it has very fine soft teeth, like the pile on velvet, in the two jaws only. 
All the opercular pieces are scaly, like the cranium and the snout. The preoper- 
culum has some indentations slightly marked towards its angle, which is rounded. - 
The bone of the operculum ends by a single fiat point. The pectoral is moderate and 
pointed ; the ventral proceeds a little further back than it, and passes it. The first 
dorsal rises in the middle of the pectoral; it has ten spiny rays, very weak and 
little elevated, the first of which is very short; the second dorsal has a spiny ray 
and thirty-three soft ones; it is nearly of equal height everywhere. The caudal is 
rounded. They are both completely scaly, so that even in the caudal it is difficult to 
count the rays. The anal only occupies a small space in length, under the middle 
of the second dorsal. It is twice as high as itis long. Its first spine is very short ; 
the second, compressed and arched like a sabre, is wider and stronger than in any 
other Scizna; there are afterwards seven soft rays and some scales between them 
The scales of the body are smooth, fine, and slightly striated on the edges. There 
is one stout spine, rather free, but not scaly, formed by the coracoidien, in the middle 
of the pectoral. The lateral line is nearly parallel to the back, and marked by simple 
but continuous tubercles. I 
This fish is nineteen or twenty inches long, is entirely of silver colour, with 
very numerous oblique, grey, or bluish lines throughout its entire length. There is 
a continuation of brown lines in the intervals of the rays of the first dorsal, and 
brown dots on those of the second. ‘he other fins have only spots. This iso 
of the numerous acquisitions to natural history, procured by M. Augustine St. 
Hilaire. He took it in the river of St. Francis, in Brazils. : ‘
