ACANTHOPTERYGII. — SCIuENADiE. 
aquila^ Cuv. et Val.), but our fishermen call it 
the Stone Basse, and confound it with another 
fish of large size, which resembles it, one of the 
Percadce. 
MAIGRE. 
Mr. Yarrell describes the colour of this rare ^ 
fish when quite fresh, as a uniform greyish silver, i 
slightly inclining to brown on the back, and n 
lightest on the belly; but the whole body as- i? 
suming a much darker tint, after it has been kept 
for a few days. The fins are reddish brown ; the : 
first dorsal, the pectorals, and the ventrals, brighter | : 
in hue than the others. The second dorsal is | 
twice as long as the first ; the caudal is, as it 
were, cut off with a straight vertical edge. 
Many of the Scicenadce have a similar power to l 
that already mentioned as characterizing the Trig- \ 
ladcE, that of producing vocal sounds. The Mai- ji 
gre’s voice is compared to the purring of a cat, 
and it utters it not only in the air when removed i 
from the water, but even when swimming consi- 
derably beneath the surface. When swimming 
in shoals, it is said the purring of the Maigre is 
audible from a depth of twenty fathoms.
