 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 Teium. If this is so the 

 Sardinian Peregrine will have to be called Falco jmnicus in 

 future. 



M. Lavauden has plotted the measurements of tlie 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 CampophagidEC, of which the 

 Ground Cuckoo- Shrike, with its terrestrial habits, is the most 

 remarkable. Mr. Mathews^s argument proves the generic 

 term Pteropodocijs to have prioi'ity over Cehlepyris, and he 

 allows three subspecies. Similarly, Graucalus takes prece- 

 dence of Coracina, while the Black-faced Cuckoo-Shrike 

 should be specifically named novcehollandice 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 thut parvirost^is 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
