occurrence of this species to the north of the Mediterranean. 
Birds of this race of Peregrine often come into the London market 
alive, in first year’s plumage, from Mogador. The typical Peregrine, 
F. peregrimu, is common enough during the autumn, -winter, and 
early spring in all parts of the Mediterranean shores that afford 
quarry, but does not, to the best of my knowledge and belief, 
breed upon any of the coasts of that sea. If the trinomial 
system should over come into general European use, I should 
certainly be inclined to designate this bird thus:— Falco peregrinns, 
sub-species 1, marinus. Hab. Mediterranean. 
This race is easily distinguishable from Falco barbarus in adult 
plumage, but before the first moult it is almost impossible to 
separate it, except by measurement, from that, in my opinion, 
perfectly distinct species, although, as 1 have before stated (cf. 
‘Ibis,’ loc. 8Upr. cit.), I am convinced that in many cases this 
Mediterranean Percgrino is the “ Barbary Falcon ” of old writers 
on falconry. 
Of the truo Barbary Falcon, Falco barbarus of 0. Salvin 
(‘Ibis,’ 1855), I know but very little in its wild state, having 
only met with it on two occasions in the south of Sardinia, but 
I have purchased many young and two or three moulted birds of 
this species from Mr. Castang of Leadenhall market, who assured 
me that they were all shipped at Mogador. In the adult plumage 
this bird is always to be distinguished from Falco punicus by the 
greyer colour of the upper parts, the constant bright rufous nape, 
and general reddish ground-colour of under parts, but is, in my 
opinion, specifically inseparable from Falco babylonicus, the Red- 
naped Sliahin of Indian falconers. The present bird is very 
considerably smaller than the typical F. babylonicus, but may, 
I think, fairly be considered as a small western race of that 
species. I have been singularly unfortunate with my Barbary 
Falcons, and in a majority of cases have failed to keep the young 
birds through their first moult. To the eye of a falconer this 
little Hawk is the model of perfection in shape, and it is pre- 
eminent for courage and speed ; but I greatly fear that our country 
is too cold, or more probably too damp, for the full display of the 
capabilities of these birds in a trained state. 
Of the Red-naped Shahin, Falco babylonicus I have only had 
one alive in captivity ; this bird, a very beautiful adult female,
