area, as the divisions are extremely ai'l^itrary, and however suitable 

 to the district under treatment, are not of sufficiently general 

 scope to be applicable to other countries. Therefore we must 

 look at Mr More's j^iiper rather in the light of a practically finished 

 work, than as a model to workers in less known areas. 



The same may almost be said of another work, that by Dr 

 Salvadori, or rather of the tables contained in it — " Fauna d'ltalia, 

 Uccelli ; Introduzione." In these the author introduces a much 

 larger set of observations than Mr More does, and records the 

 faunal value of each species in each of three zones, viz.. Zona setten- 

 ■ trionale, Zona centrale, and Zona ineridionale, and also the insular 

 groups, or Italia insulare; and in each of the columns allotted to these 

 zones he indicates the species which are — stationary, s; summer 

 residents, me; winter residents, mi; of regular passage, ])t; of 

 irregular passage, jji; of occasional or accidental occurrence, a; etc. 

 As will be seen by the specimen given below, any of the above 

 particulars relating to the species can easily be found by the aid 

 of the perpendicular columns opposite the names of the species. 

 This plan of Salvadori's has more jjoioer of applicalility than Mr 

 More's, but the symbols or contractions admit, I think, of 

 improvement still in that respect.
