indebted for many of the details now gathered together for 

 the first time. 



The zoologists of North Wales form the subject of an 

 initial chapter, which is followed by a full bibliography, 

 and this again by a graphic sketch of the physical features 

 of the whole area, Avhich is taken to include the counties of 

 Anglesey, Carnarvon, Denbigh, Flint, Merioneth, and Mont- 

 gomery. The routes of bird-migration are a separate subject 

 of consideration, and 350 pages are devoted to the species 

 of birds alone, some 250 in number. The list is excellently 

 written and, where necessary, the details are given under the 

 heads of the several counties — a most important point for 

 North Wales, Avhere the distribution of the forms is even 

 now imperfectly apprehended. In conclusion, we may draw 

 attention to the breeding in the district of the White Wagtail, 

 Siskin, and Crossbill, the increase of the Hawfinch and 

 Turtle-Dove, and the interval stated to elapse between the 

 laying of the eggs of the Buzzard. A possible case of the 

 breeding of the Wigeon near Bala is given for what it is 

 worth, while we are informed that there is as yet no certain 

 record of a Twite's nest in the area treated. 



35. Godman's 'Monograph of the Petrels' 



[A. Monograph of the Petrels (Order Tubinares). By F. Du Cane 

 Godman, D.C.L, F.E.S., President of the British Ornithologists' Union, 

 &c., &c. With hand-coloured Plates by J. G. Keulemans. In Five 

 Parts. Part I. Witherby & Co. : December, 1907.] 



We have already ('Ibis,' 1907, p. 515) stated the circum- 

 stances under which the illustrated work on the Petrels 

 projected by the late Mr. Osbert Salviu and Dr. Godman 

 came to a stop in consequence of Salvin's death, and have 

 announced Dr. Godman's recent determination to complete 

 the work as nearly as possible in the manner in wjiich it was 

 originally planned. The Tubinares, which, besides the 

 typical Petrels, contain the Shearwaters, Fulmars, and 

 Albatroses, had long been one of the favourite groups of 

 Salvin, who prepared in 1896 the well-known account 

 of them contained in the 25th volume of the ' Catalogue of
