Note 8 — PINNIPEDIA.
Reading edition
The Seal of the Caspian Sea was described as a variety of Ph. vitulina, by Pallas, and as a distinct species, by Nilsson, under the name of Ph. caspica. It is, however, notwithstanding its abundance, very little known, and may, probably, prove to be more nearly allied to the next species. The yearly average of this species taken in for the six years ending 1872, as given by Schultz, is 130,000.
