literature and compared a large number of examples in the 
Paris Museum, his own collection, and elsewhere. 
He comes to very much the same conclusions as Dr. 
Hartert, except that he believes that Falco punicus of 
Levaillant, jun., is identical with Falco brookei of Sharpe, 
and not with F. peregrinoides Temm. If this is so the 
Sardinian Peregrine will have to be called Falco punicus in 
future. 
M. Lavauden has plotted the measurements of the three 
Mediterranean Peregrines, of which he has examined and 
measured 287 adult examples, so as to form an ingenious 
curve which illustrates very plainly the variation in the wing- 
measurements of the three forms. 
Mathews on Australian Birds. 
[The Birds of Australia. By Gregory M. Mathews. Vol. ix. pt. 3 ; 
pp. 97-144, pis. 412-418. London (Witherby), June 20th, 1921.] 
A very important discovery is recorded in this part by the 
author—namely, that the types of Gould’s species are not 
all at Philadelphia. Many are in the British Museum, and 
Mr. Mathews devotes several pages [105-107] to the subject, 
which will be fully discussed later. The present part is 
concerned with seven species of Campophagidse, of which the 
Ground Cuckoo-Shrike, with its terrestrial habits, is the most 
remarkable. Mr. Mathews’s argument proves the generic 
term Pteropodocys to have priority over Ceblepyris , and he 
allows three subspecies. Similarly, Graucalus takes prece¬ 
dence of Coracina , while the Black-faced Cuckoo-Shrike 
should be specifically named nov&hollandice and not melanops 
[p. 113]. This species was painted by Ellis, and has been 
confounded with Latham’s robustus , which is the lesser 
species. Six subspecies are accepted, for one of which 
the name melanops is used. The type appears to have 
come from Tasmania, so that parvirostris is a synonym. 
G. hypoleucus has four Australian subspecies, but it is 
evident that there are others that are extralimital. The 
habits of this northern form and of the Little Cuckoo-Shrike 
need further attention ; those of the other species have been
