This species appears to be very rare in the British seas; nor am I aware of any description of a native specimen on record. Grew has incidentally thrown out a remark * that it is sometimes found upon the Cornish coast. Low states, that according to information given to him, it is met with in the neighbourhood of the Orkneys. None of our other English authors, that I am aware, have specified any localities in which it has occurred. The description given above is taken from the Faune Francois. It may be of use in enabling future observers to identify this species: it must be remembered, however, that two or more appear to have been confounded under the name of Carcharias; and possibly it may not belong to the one which has been met with in the British seas. According to Cuvier, the S. Carcharias of Bloch† is very distinct. The present species is widely distributed, and attains to a very large size. It is very voracious, and much dreaded by navigators.
