all around, except that the extreme margin, especially at sides of apex, is hyaline 
and without sculpture; basal circuli conspicuously denser than apical or lateral. 
These scales do not differ materially from those of C. hippos. 
STROMATEID^: (including NOMEIDAil). 
Psenes whiteleggii Waite. Queensland. Scales very variable, the largest 
scarcely mm. broad, broader than long; but others, probably from the caudal 
region, smaller, and longer than broad; margin simple; three or fewer basal 
radii; basal margin variably but usually strongly lobed ; circuli normal, widely 
spaced. 
Gobiomorus gronovii has scales of the same general type, but without 
radii. The scales of Poronotiis iriacantJnis are much larger than those of PseneSy 
but otherwise very similar, though with much denser circuli. The lateral circuli 
are often distinctly angular, and the same feature may be seen in some scales of 
Psenes. 
PEMPHERID^. 
Pempheris compressus Shaw. Port Jackson. Scales (from different 
parts of the fish, presumably) differ greatly in size, the largest are nearly 
mm. bi'oad and fully 3^ long; a strong arched ridge runs across the scale just 
above the nucleus, separating the larger api(*al held, which is Avithout circuli or 
other distinct sculpture, except the mai'giunl ctenoid area; marginal teeth long 
and sharp, on all the scales examined; submarginal ctenoid elements broader 
than long; sides of apical field variably constricted (concave) just above the 
ends of the transverse ridge; part of scale below the ridge covered Avith normal 
circuli ; basal radii many, but feeble, being folds rather than true radii, arranged 
in a fan-like manner (except in latinucleate scales) ; basal margin of larger 
scales straight, Aveakly crenulate, but some of the smaller scales have three lobes, 
the median one very large, separated from the others by deep sinuses. 
Parapriacanthus elongatns McCulloch. Bass Straits. Scales about 
3 mm. broad and 2 long; divided into tAAu parts more or less as in Pempheris 
compressnsy but Avholly cycloid, or AAuth the apical margin throAAU into one or 
tAvo broad dentiform prominences, AAuthout any cycloid patch ; transverse ridge 
straighter and Aveaker than in P. compressus ; apical half of scale AA'ithout circuli, 
basal half with strong normal circuli; at the beginning of the basal half the 
scale suddenly Avidens, making an angle with the vertical sides of the apical 
half; no distinct basal radii or lobes, but there are very indistinct traces of 
radial folds. 
These scales are very remarkable ; those of P. compressus are quite unlike 
those of the species of Pempheris previously seen (iMem. Q;ueensl. i\Ius., Dec. 
1913, p. 54). In the presence of a distinct ctenoid patch. P. compressus resembles 
Leptobram,a mullerij but the submarginal elements in that fish are A^ery different,
