The Italian Sea-Pen differs from the Britim fo much, 

 that there is no room to doubt but they are very different 

 fpecies. The Britifh is much longer, more flender, and 

 not fo fiemy as the Italian ; but the broad, warted, midrib 

 and fpiny fins of the latter, diftinguifh it plainly ; be- 

 iides, the denticles are placed fo thick as to appear like a 

 double row. This varies in color from a deep red to a 

 pale red. Doctor Shaw obferves of this, that on the 

 coaft of Algiers it fends forth fo great a light in the night, 

 that the fimermen can diftinguifh the fiih as they fwim by

 brought from the coaft of Italy. I am indebted to my 

 learned friend Thomas Pennant, Efq. F. R. S. for the 

 curious fpecimen reprefented in the Philofophical Tranf- 

 actions.

I have changed Bohadfch's name of grifea to fpinofa, 

 as being more defcriptive of its character, the fins differing 

 from any of the fpecies yet known by their long fpines.
