2. Rhombus triacanthus, Pecx. 
Body ovate, very much compressed, particularly at the abdomen ; more elongated than the 
preceding ; its anterior dorsal and anal rays slightly elevated. Ofa leaden color upon the back, 
lighter on the sides, silvery upon the abdomen. Cheeks, intermaxillaries, chin, base of pec- 
torals, and base of caudal fin, together with more or less of the abdomen, sprinkled with very 
minute black dots. Opercles cupreous. Besides the lateral line are two others, one above 
and the other beneath the lateral, which curve backwards with the body and terminate at the 
fleshy portion of the tail. Twenty or thirty small circular black punctures, the orifices 
of numerous ducts, on each side of the base of the dorsal fin.

If all the species of this genus have the ¢hree spines which are so well marked in this spe- 
cies, it may be thought necessary to change Peck’s specific name, which now has the pri- 
ority ; in which case Mitchill’s specific name will be very appropriately substituted. 
GENUS XXV. LAMPRIS, Rerzivs. 
Body oval, greatly compressed, scales small ; a single elevated and elon- 
gated dorsal fin, which has but one small spine at the base of its anterior edge ; 
there are ten very long rays to each ventral ; the lobes of their caudal are also 
very long, but all these prolongations become worn away with age. Sides of 
the tail carinated ; teeth wanting ; branchiostegous rays, seven. 
1. Lampris guttatus, Rerzius. 
The upper part of the back and sides are of a rich green, reflecting both purple and gold 
in different lights, passing into yellowish green below; above and beneath the lateral line 
are various round yellowish-white spots, from which the fish received the name of Luna; 
the irides are scarlet ; all the fins are bright vermilion.
