624 Recently published Ornithological Works. 



Mr. N. H. Foster continues his observations on the weight 

 of birds' eggs {of. vol. xi. p. 237, vol. xii. p. 295), and both 

 the January and February numbers are entirely devoted to 

 a survey of the Natural History of Lambay Island, Co. 

 Dublin, wherein Mr. R. Patterson gives an account of the birds 

 (pp. 23-31). The rarest species now breeding there are the 

 Manx Shearwater and the Black Guillemot, but the Raven, 

 Chough, and Sea-Eagle are reported to have nested there in 

 former days. 



97. Martorelli on Lanius homeyeri in Italy. 



[II Lanius homeyeri, Cabanis, in Italia, nota ornitologica del socio Prof. 

 Giacinto Martorelli. Atti Soc. Ital. Sc. Nat. xlvi. (1908).] 



Although several of our leading systematists have lately 

 dealt with Lanius excubitor and its nearly allied forms, they 

 have been by no means unanimous in the conclusions arrived 

 at on this difficult subject. Prof. Martorelli, having paid great 

 attention to the question for some years, has come to the 

 conclusion that besides the typical Lanius excubitor and 

 L. borealis a third closely related form also occurs in Italy 

 not unfrequently, and that this form is the L. ho7neyeri 

 of Cabanis, which is the south-eastern representative of 

 L. excubitor. A nicely coloured figure is given of this bird. 



98. Miller on the Manakins of the Genus Chiroxiphia. 



[A Review of the Manakins of the Genus Chiro.xiphia. By W. De 

 Witt Miller. Bull. Amer. Mus. Nat. Hist. xxiv. p. 331 (1908).] 



Mr. Miller reviews the species of the beautiful Pipriue 

 genus Chiroxiphia, and recognises eight forms as entitled to 

 specific rank. Of these C. napensis, the closely allied repre- 

 sentative of C. pareola on the Rio Napo, is described as a 

 new species. As no intergradation is known between this 

 form and its allies, " it has seemed best to give it full specific 

 rank." C. pareola atlantica of Dalmas, from Tobago, and 

 C. p. boliviana of Allen are likewise treated as full species. 



We are glad to observe that the author does not recognise 

 the so-called genera ChirojJrion and Cercoph<sna, but unites 

 them both to Chiroxiphia. Good coloured figures are given 

 of C. boliviana and C. napensis.
