nattereri and V. mystacinus) and four Cetaceans (Balenop- 
tera borealis, Grampus griseus, Lagenorhynchus albirostris, 
and Delphinus delphis). Of these, forty-eight have valid 
claims to a place in the present catalogue, and no fewer than 
forty-six of them have occurred within the Forth area. This 
is exclusive of Natterer’s Bat, the record of which requires 
confirmation. The Greenland or Harp Seal (Phoca gren- 
landica), and the Dormouse (Muscardinus avellanarius)— 
both perhaps less likely to occur—have also been recorded, 
but on insufficient evidence, and are consequently likewise 
excluded. The details of the comparison are given in the 
following table, which also contains the figures for the British 
Isles as a whole :—

The number by which the Edinburgh list falls short of the 
British is largely made up of Bats, while the deficiency, as 
compared with the Scottish list, consists almost entirely of 
Cetaceans and Seals. The British Bats are mainly confined to 
England, several of them being of rare occurrence even there, 
so that we can scarcely hope to increase our list by discoveries 
in this group to the extent of more than two or three. The 
occurrence of any further marine Carnivora on our coasts is 
not at all likely; but the identification of one or two 
additional Cetaceans is probably only a question of time. It 
is therefore to the Bats and Cetaceans that we must look for 
any augmentation of the list. The latter group may safely be 
left in the hands of Sir William Turner, LL.D., F.R.S., whose 
investigations have already thrown so much light on this section 
1V. murinus, V. discolor, and V. dasycneme, being in all likelihood 
mere importations, are excluded.
