 for 1920 ; 2 nos.] 



The second volume of ^ El Hornero,' completed in two 

 numbers, contains a good deal of information relating to 

 the birds of the Argentine and other neighbouring States 

 and maintains the promise of the first. Sen. J. Tremoleras 

 contributes a list of the birds of Uruguay based on 30 years' 

 observation. The last general list was that of Mr, O. V. 

 Aplin, published in ' The Ibis ' for ISQi, and we are glad to 

 see Sen. Tremoleras quotes him and gives him all the credit 

 due to him. Mr. A. G. Bennett, of Port Stanley, Falkland 

 Islands, sends good notes and photographs on birds observed 

 by him in the South Shetlands and South Orkneys. This 

 article, though originally written in English, is trans- 

 lated into Spanish for the pages of ' Kl Hornero.' Some 

 account of the nesting habits and the young birds of the 

 Maguari Stork,, also accompanied by photographs, is given 

 by Sen. M. Fernandez, of La Plata. Those curious external 

 insect parasites which prey on Birds and some Mammals, 

 and which form the group Mallophaga, have been a good 

 deal studied of late years. Seii, F. Lahille has collected and 

 published a list of all those which are found on Argentine 

 birds. They perhaps should not be regarded as parasitic, 

 but rather as epizoic, as they do not appear to injure their 

 host in any way, but feed on the epidermal products, such 

 as the feathers and hairs. Little attention has been paid to 

 the birds of the " chaco " region of north-western Argentina, 

 since Prof. Graham Ker visited it in 1890-1, and we are 

 glad to see in the present volume a long article on the birds 

 of this region by Senor E. L, Arribalzaga. Finally, we 

 must mention Dr. R. Dabbene^s own contributions to the 

 volume. He has completed an account of the Argentine 

 Penguins with descriptive keys, ranges and distribution, 

 and outline figures to illustrate the differences of the seven
