and Mr. Gurney enumerates their progress and numbers 

 in Norfolk in the short article the title of which is quoted 

 above. 



The second note deals with a rare Hawk described in 1876 

 by Salvin from Puna I., off the coast of Ecuador. Two 

 examples of this rare species have recently been added to 

 the Norwich Museum. 



The third title is that of a pamphlet containing a list of 

 Mr. Gurney's various papers on ornithological subjects, 

 dating from 186G, when he contributed to 'The Ibis' a 

 short note on " a variety of the Swallow/' which he believed 

 to be Hirundo saviffnii, but which was afterwards found to 

 be a mistake (see B.O.U. List Brit. Birds, new ed. p. 330). 



Loomis on the Petrels etc. 



[A Review of tlie Albatrosaes, Petrels, and Diving Petrels. By 

 Leverett Mills Loomis. Proceedings of the California Academy of 

 Sciences, Fourth series, vol. ii. pt. ii. No. 12, pp. 1-187, pis. 1-17,

This review is apparently based on the collection of Petrels 

 made on account of the Academy at the Galapagos Islands 

 in 1905-1906 by an expedition under the well-known col- 

 lector, Mr. Rolls Howard Beck. The review consists of 

 six parts, the first being a short historic sketch dividing 

 the study of Petrels into four periods — the pre-Couesian, 

 Couesian, Salvinian, and Godmanian. While fully agreeing 

 that the pre-eminent student was Cones, the last period may 

 not later be termed the Godmanian, as Godman's ' Mono- 

 graph ' was simply, as admitted by himself, the completion 

 of Salvin's work. It is unfortunate that the present review 

 scarcely passes the standard of the pre-Couesian period, as 

 by usage of a rough lumping nature our knowledge of Petrels 

 appears to belong to that period. The second part treats of 

 geographic distribution in a superficial manner while the 

 third consists of remarks on migration, which may be con- 

 sidered in relation to other data not approved of by the author. 

 So little is known of the breeding- places and habits of Petrels 

 that the exodus-migrations so surely spoken about are purely
