HIS fpecies derives its Latin name from the 
inftruments fullers make ufe of in fmoothing 
cloth, the back being rough, with {mall {pines 
like that. 
‘Thefe fpines are fpread not only over the back, 
but the upper fide of the fins and the head: near 
each eye is a femicircular order of larger fpines, and 
about the nofe are a few others; a row of the 
fame kind go half way down the back: the tail 
is armed with a double row of ftill greater fpines. 
The color of the upper part is afh-color, mixed 
with yellow; the lower part of the body entirely 
white. 
This fpecies we believe to be rare, having never 
met with it; therefore are obliged to borrow our 
defcription from Mr. Willoughby.
