Anthias formosus, the Hemulon elegans, Cuy. MSS., for, instead of 
the longitudinal vitte we have here numerous oblique lines. This cha- 
racter distinguishes it equally from every other described species with 
which I am acquainted of the genus Hemulon, recently proposed among 
the Sparide by M. Cuvier, with the single exception of his Hem. hete- 
rodon, the Diabase rayé de jaune of M. Desmarest. In this latter there 
are, however, three vitte along each side of the back, which are wanting 
in our fish, the oblique lines being continued in it to the base of the 
dorsal fin. I would therefore propose to characterize it as a new species. 
Diasasis oBLiquatus. Diab. flavescens, capite vittis ceruleis duo- 
decim, corpore linets ceruleis obliquis numerosis. 
D. 42. P15. Via. As. 16. 
On a yellowish, somewhat fuscous, ground, (perhaps altered by the 
spirit in which the specimen has been immersed for about three months, ) 
the markings are pale blue, in numerous wtte: those on the head and 
opercula, which are somewhat broader, and more deeply coloured than 
those of the body, are nearly longitudinal, about twelve in number : those 
of the body are oblique, directed upwards and backwards. The latter 
are formed by lines passing across the middle of each scale, and are con- 
sequently numerous, not less than sixteen or seventeen being crossed by 
a line drawn from the junction of the spinous and soft portions of the 
dorsal fin to the belly in front of the anus. On the tail, behind the dor- 
sal and anal fins, the markings become longitudinal, in about nine rows. 
The fins, especially in their scaly soft portions, are more fuscous than 
the body : into these the markings do not extend. The lateral line, 
deflected opposite to the extremity of the dorsal fin, is yellow, and is 
accompanied below by a blue line; a similar line, but more indistinct, 
passes along its upper edge. The caudal fin is forked; the spines of the 
dorsal are filamentous. 
The front and the extreme teeth in each jaw, especially in the upper, 
are longer and stronger than the others, and are somewhat hooked ; a 
variance from the generic mark ‘dents en velours’’ indicated by M. 
Cuvier. His characters may perhaps be erroneous in this respect, or the 
structure may be peculiar to the present species, the only one of the 
genus I have yet examined. 
In this description I have omitted several points which form part of the 
generic marks indicated by M. Cuvier, whose name’ for the genus’ (/He-
