houses at Mr. Philip Hadds's Nursery Gardens, Swanley, 

 Kent. This is the second occasion on which this species 

 has selected this remarkable building-site. 



Mr. BuNYARD also exhibited eggs of the following species: — 

 A set of four eggs of Eversmann's Warbler {Phylloscupus 

 borealis, Bias.), from the Kola Peninsula, taken by Mr. Helge 

 Lilliestiema on July the 1st, 1903. He called attention to 

 the fact that the eggs of this species more nearly resemble 

 the eggs of the Chiffchaff (P. rufus, Bechst.) than those of 

 the Willow-Wren (P. trochilus, Linn.); in support of this 

 statement a series of eggs of the two last named species 

 were shown. 



Two eggs of the Stonechat {Pratincola rubicola, Linn.) 

 with a distinct blue ground and a total absence of any 

 greenish tinge, the markings being in the form of well- 

 defined spots, forming a zone round the larger end. 



Mr. W. P. Pycraft exhibited a skull, and briefly described 

 the skeleton, of Palaeocorax moriorum, a fossil Raven from 

 the Chatham Is., New Zealand. He pointed out that the 

 skeleton was that of a bird intermediate in size between 

 the typical Raven (Corvus cor ax, Linn.) and the Carrion- Crow 

 (Corvus corone, Linn.). 



The skull was, however, easily distinguishable from that 

 of all other Corvidae by the larger size of the maxillo-palatine 

 plate and the breadth of the maxillo-palatine processes. 

 The wing was relatively shorter than in either the Raven or 

 the Crow, while the keel of the sternum was relatively 

 shallower. From this it was inferred that the power of flight 

 in this bird was on the wane at the time of its extinction. 

 This inference was confirmed by the fact that the leg was 

 actually longer than that of either the Raven or the Crow. 



Mr. Pycraft also made some remarks on the number and 



arrangement of the tail-feathers in the Dabchick {Podicipes 

 fluviatilis). He stated that their arrangement was unique 

 among birds, since these feathers ran in a double, parallel 

 series, divided by a narrow space, and were so turned
