Recently published Ornithological Works. 171 
for a complete list of British Birds, printed in such a 
form that it could be cut up and used for labelling 
specimens, Mr. Ogilvie-Grant has prepared the present 
catalogue, which is specially adapted for that purpose. So 
many additions to the British Avifauna have been made 
since Howard Saunders’s 4 List of British Birds’ was revised 
in 1907 that a new list was much wanted. 
The new List contains the names of 442 species, 
considered to be entitled to a place in the British Avifauna. 
Besides these, Mr. Ogilvie-Grant gives the names of others, 
of which “ the history is doubtful” or cc which have, 
perhaps, been artificially introduced,” but these names 
are not numbered and are placed in square brackets. The 
442 numbered species are divided into five categories :—• 
(1) Residents; (2) Regular Summer Visitors that Breed; 
(3) Regular Autumn, Winter, or Spring Visitors that do 
not Breed ; (4) Occasional Visitors that in former days used 
to Breed; (5) Occasional Visitors that have never been known 
to Breed. The exact “ status ” of each bird, according to 
the author’s view, is clearly shown in a series of columns 
following its name, so that it is very readily ascertainable. 
Another good feature in this List is that the names of 
the numerous species recently added to the British Avifauna 
are all carefully inserted in their places, and references are 
given to the works in which their occurrences in this 
country have been recorded. This will make the List very 
useful to the collector, who, up to the present time, has 
been obliged to hunt up such records in a dozen different 
periodicals. But, on the other hand, the classification 
adopted, which appears to be nearly that of the Bird-Gallery 
in the British Museum, beginning with the lower forms 
and ending with the Passeres, will, in our opinion, be far 
from popular. The author quotes Saunders’s f Manual 9 
throughout his List, and refers to Saunders’s dicta con¬ 
tinually. Why, then, did he not use Saunders’s classification, 
which is nearly the same as that of the 4 Ibis List,’ and 
is familiar to all British Ornithologists ? We are also 
of opinion that the addition of the authority to the scientific
