Willughby, Catulus minor3 Ray, Catulus minor vulgaris3 Bellonius, Muftelus ftel- 
laris tertius. The Venetians confound it with the former fpecies, under the name of 
Pefce Gattoq and we, in Cornwall, call it the rough Hound, or Morgay.

This fpecies is frequent in the Ocean, but is rarely met with in the Mediterranean 3 
we have it fometimes about our own coafts, but it is much more common in many 
other places: the aniients were very well acquainted with it. ./Elian calls it Vxuvy.(& - 
Rondelet, Gefner, Aldrovand, Willughby, and Ray, Galeus Glaucus 5 Charleton,
