and a hundred and one other causes may govern the produc- 

 tion of one aberrant egg or of one clutch of sucli eggs, but 

 the causes of normal coloration, shape and texture are far 

 deeper and far more worth wbile investigation. 



The present double number deals practically with the 

 collection and exhibition of eggs, but in future numbers we 

 shall look forward to seeing the " why and the wherefore'' 

 of various oological points dealt with and explained. 



We wish the Museum and Journal the greatest success, 

 and recommend the latter to all oologists for careful study.

To the courtesy of ]\Ir, N. Kuroda, F.M.B.O.U., we are 

 indebted for a complete set of the Japanese journal of 

 ornithology, uliich we are very glad to see, though we fear 

 we are unable to read the contents. Each number contains 

 about 30 pages of text in Japanese and a good many 

 half-tone illustraticnis from photographs and generally a 

 coloured plate, and the whole is executed in a most artistic 

 manner. 



The first number contains a picturesque coloured figure 

 of the Pheasant-tailed Jacana, whi{;h however, so far as we 

 are aware, is not found in Japan. The second number has 

 a paper on the birds of the Pelew, Marianne, and Caroline 

 groups of the western Pacific, recently taken over by Japan 

 from the Germa\is. Theie are descriptions of two new sub- 

 species by Mr. Kuroda — CollocuUa fuciphaga rukemis and 

 Hulcgon chloj'is vanikorensis, which are figured in colour. 

 The descriptions of the new forms are also translated into 

 English, and the list is partly in English. Another number 

 has a description of a new Woodpecker, Dryobates leucoios 

 quelpartensis, from Quelpart Island in Korea Straits, by 

 Mr. Kuroda and Mr. T. Mori, also trauj-lated. Another 

 paper contains tlie account of the interesting Shelduck^ 

 Pseudutadorna cristata, which has already been noticed in 

 our pages (Ibis, 1918, p. 732).
