310 Zoological Society :— 
The following synonyms will therefore have to be added to those 
which I have placed under Monachus albiventer in the Catalogue of 
Seals in the British Museum, p. 18 :— 
Heliophoca atlantica, Gray, Ann. & Mag. N. H. 1854; Arch. f. 
Nat. 1855, p. 40. 
Phoca leporina, Verreaux, not of Lepechin. 
Hab. North and south shores of the Mediterranean, fle d’Oléron, 
and Madeira. 
These facts are interesting as showing that the Seal which was for- 
merly believed to be confined to the north shore of the Mediterranean 
is also found on the southern one and on the islands of the Atlantic. 
Nilsson, in his excellent monograph on the genus, after having 
examined all the materials that he could find in the different mu- 
seums, reduced the number of species of Seals to fourteen. 
We have now in the British Museum, as by the following list 
will appear, twenty-four most distinct species, established upon the 
examination of the osteological as well as the external characters of 
the animals.
