The fishes of this genus only differ from those of the preceding one in their teeth, which are very short and crowded (en velours ras).(4) They all inhabit the Indian ocean. GLYPHisonoN, Lacep. Operculum and preoperculum entire; a single range of trenchant and generally emarginated teeth. They are found in the Atlantic,( 5) but the Indian ocean pro· duces many more.(6) Some of them are distinguished from the others by numerous spines in the anal.(7) HELIASUS.

The Sparoides, like the Scienoides, have a palate destitute of teeth. Their general figure and several details of their organization are the same; they are also covered with scales more or less large, but they have none on the fins. Their muzzle is not gibbous, nor the bones of their head cavernous; there are neither indentations in their preoperculum, nor spines on their operculum ; their pylorus is furnished with crecal appendages. They never have more than six rays in the branchiro. They are divided according to the form of their teeth. In the first tribe, that of SPARus, Cuv. the sides of the jaws are furnished with round molars en paves; we subdivide it into five genera. SARGus, Cuv. Trenchant incisors in front of' the jaws almost similar to those of Man. Several of them which differ but little from each other inhabit the Mediterranean, and are even found in the gulf of Gascony. They are marked with vertical, black bands on a silver ground.(2) Some hav-e emarginated incisors. (3) The round molars of others are on a single line and very small.
