congestion along the double migration-lines in autumn and 

 in spring. 



I venture to throw out the hint, also, that a study of the 

 bulking of Woodcocks in 1901-2 at the northernmost portions 

 of the Scottish Isles (Shetland has a record year for Woodcocks 

 in 1901-2) and all along our east coasts, to the exclusion of 

 the west side, due to fierce south-easterly winds at the time 

 of their migrations— fierce and of long persistency— may 

 supply parallel data, though taking place in a diametrically 

 opposite direction by the two species presently under treat- 

 ment. 



When great and phenomenal invasions of species of foreign 

 origin take place, the greatest " bulking'' occurs, first at the 

 nearest, or yfrj/- reached land ; and second, at their ulti?na 

 Thule—2iS in the cases instanced above of the Grey Phalaropes 

 in 1886 and 1891, and of the Woodcocks in Shetland in 1901-2. 

 Another instance is that of the Little Auks in 1895, as recorded 

 by Mr. Eagle Clarke, and by Mr. J. Paterson for Scottish 

 areas. (See Map in A. S. N. //., 1895).

AN INDEX OF ANIMALS. 



Index Animallum sive Index Noininum quae ab ad. mdcci^viii. 

 geueribus et speciebus animalium imposita sunt. C. D. Sherborn. 

 Section I. mdcclviii.-mdccc. Pp. 1195. Cambridge: University

All working naturalists know that for ten years past Mr. C. D. Sherborn 

 has been engaged at the British Museum, under the auspices of a Com- 

 mittee of the British Association, working up a great comprehensive 

 index of animal names. The present bulky volume represents the first 

 published instalment of his arduous task. If nearly twelve hundred pages 

 are required for the zoological nomenclature of the eighteenth century, 

 what will be the extent of the record for the nineteenth ? 



It is impossible to speak too highly of the thoroughness and accuracy 

 with which Mr. Sherborn has done his tedious and self-denying work. 

 The list of books consulted by him fills forty-five closely-printed pages. 

 The index itself is arranged under species, the generic names used with anv
