n- by them: and if we may judge by their figures of each, it fhould 
. feem that the firft defcribed was the moft plentiful. That figured 
in Gener is far from a bad reprefentation, and the one engraved 
t by Knorr in his De/ice is fufficiently accurate. This fpecies differs 
- from the firft, in having the /z more narrow in proportion at 
the bafe, and the whole of it more flender in all its parts ; whereas 
- the firft is very broad at the bafe, and tapers confiderably from 
thence to the point. The fpines on each fide alfo are longer 
and more flender, and vary from twenty-five to thirty-four in the 
different fpecimens: we > have indeed been informed of one which

; but we muft confefs that we have never been fortunate enough ta

= fize as the former, and in the general make and fhape of the body 
does not materially differ.
