admirable reports, relating to the year 1904. The specimens 

 of birds sent to the Zoological Museum of Copenhagen from 

 the Lightships and Lighthouses in that year were 620, which 

 are referred to 56 species, against 750 specimens belonging 

 to 50 species in 1903 (see ' Ibis/ 1904, p. 163). The notes 

 on them are arranged in the usual methodical manner. 

 The most numerous species in 1904 were Alauda arvensis 

 (248 specimens), Turdus musicus (38), and Erithacus rube- 

 cula (38). 



33. Wytsman's ' Genera Avium.' 



[' Genera Avium,' edited by P. Wytsman. With Contributions by 

 Messrs. P. L.Sclater, R, Bowdler Sharpe, W. R. 0<rilvie-Graut,E.Hartert, 

 C. L. Hellmayr, T. Salvadori, &c. Parts 1-5. Brussels, 1905.] 



We have now before us the first five parts of ' Genera 

 Avium/ the plan and scope of which have already been ex- 

 plained to our readers (see ' Ibis/ 190-1, pp. 171, 309). 



Part 1 (price 2*. lid.) contains a reprint of Mr. Hartert's 

 essay on the Eurylsemidae, which was originally issued as a 

 specimen of the projected work (see ' Ibis/ 1904, p. 309). 

 The Family is divided into two Subfamilies, Calyptomenhice 

 and Eurylseminse. Of the former Mr. Hartert recognises 

 one genus with 3 species, of the latter six genera with 8 

 species and 7 subspecies. The coloured plate by Keulemans 

 represents Serilophus lunatus rothschildi and details of other 

 species. 



Part 2 (price 3s. Id.) contains an account of the Family 

 Todidse, by Mr. P. Wytsman. This Family has only the one 

 genus Todus, a very peculiar group, restricted to the Greater 

 Antilles. It has four representative forms in the four islands 

 in which it occurs, which the author treats as subspecies ! 

 As the forms are sufficiently distinct to be recognised we 

 cannot agree to this view, and prefer to consider them full 

 species, as all former authors have done. The four species 

 are all figured in the coloured plate. 



Part 3 (price 2*. 9d.), by Count Salvadori, contains the 

 Stringopidse, with the single genus Stringops (of New Zealand), 

 which has one certain species, for the so-called S. greyi, as
