wliich last proved so active that it escaped rae and conccal( d 

 itself iu the rocks. So exactly do these birds assimilate the 

 grey-coloured earth and pink water of their feeding-grounds, 

 that it is most difficult to distinguish them, even at very 

 close range, when they are at rest ; it is then their shadow, 

 rather than their actual form, which reveals their presence 

 in the clear, soft sunlight of these high latitudes. They 

 run about at a great pace, seeming quite to flit over the 

 ground. The fl'ght is dashing, headlong, and twisting — 

 difficult to follow with the eye — and usually they negotiate 

 a considerable distance before alighting again.'' 



02. Godman's 'Monograph of the Petrels' 



[A Monograph of the Petrels (Order Tubinares). By F. Da Cnne 

 (lodman, D.C.L., F.R.S., President of tlie l>ritish Ornithologists' Union. 

 AVith hand-coloured Plates by J. G. Keulemans. Part II. March 

 1908. Witlierby & Co.] 



In our notice of the first part of this important Avork 

 (above, p. 367j we have fully explained its aims and objects. 

 We need now only say that the second part fully deserves 

 the same commendation as the first. After finishing the 

 account of the Storm-Petrels with the little-known Cymo- 

 droma moestissima, the author devotes his attention to the 

 Shearwaters [Puffini), of which he recognizes 25 species. 

 All but 5 of these are well figured in Keulemans's excellent 

 plates, which will be of great assistance to Ornithologists 

 who have to determine specimens of this difficult group. Two 

 of them, Pvffinus gravis (olim major) and P. anglorum, are 

 well-known members of our Fauna, and two others (P. griseus 

 and P. ohscurm) are occasional stragglers into the British 

 Area. But it seems that P. yelkouanus (the Mediterranean 

 representative of P. anglorum) should also be included in 

 the British List, as several undoubted examples of it have 

 occurred on our southern and eastern coasts *.
