Note 14 — Chapter II
Reading edition
It would be interesting, but at the same time difficult, to ascertain where one particular species commences and another terminates, and the extent of their range. In the summer season they are found off the Cape of Good Hope, Port Jackson, and even on the banks of Newfoundland; and I have good authority for asserting that in the month of August, in even more than one year, they have been seen in Plymouth Sound.
