executed tliat they might easily be mistaken for new species 

 by those without some knowledge of ornithology. 



They had been sent by Dr. Hopkinson to show that even 

 in that remote part of Africa the simple-minded negro 

 had learned how to make money by selling these "' fakes " 

 to the younger French traders in Gambia. 



The Rev. F. C. H. Jouruain exhibited a series of three 

 clutches of eggs of Richard's Pipit [Anthisrichardirichardi, 

 Vieill.), collected by Herr 0. Bamberg on his journey to 

 Transbaikalia and North Mongolia in 1908. Side by side 

 with these was shown a clutch of Anthus richardi striolatus, 

 Blyth, obtained by Mr. E. C. Stuart Baker on Shillong Peak, 

 Assam. The clutch of A. r. striolatus agreed well with 

 specimens sent by Mr. Rickett from China and now in the 

 British Museum. Although Dr. Hartert, in his ' Vogel der 

 jjalaarktischen Fauna/ i. p. 265, regarded these two forms 

 as only subspecifically distinct, the eggs differed considerably, 

 and, strange to say, those of the smaller bird {A. r. strio- 

 latus) were rather larger than those of the larger form 

 {A. r. richardi). They also showed a constant difference 

 in the type of markings, those of A. r. striolatus being 

 decidedly bolder. 



A clutch of five eggs of tho Brown Flycatcher {Muscicapa 

 latirostris, Raffles), of which a single specimen had been 

 recorded from the south coast of England, was also 

 exhibited. It had been taken on Mount Fuji, Japan, on the 

 20th of June, 1910. 



Mr. JouRDAiN also exhibited two eggs of the Common 

 Magpie {Pica pica, L.), taken by himself in South-west 

 Derbyshire. The clutch contained six eggs, four of which 

 were almost normal in colouring, while the two eggs ex- 

 hibited were erythristic in type, the ground-colour being 

 buff or stone-colour, with red-brown spots and violet shell- 

 markings. 



Mr. JouRDAiN proceeded to make some general remarks 

 on the subject of crythrism in eggs, confining the use of the 

 name to those species in which the eggs showed two distinct
