BIRD MIGRATION. 



Report on the Immigrations of Summer Residents In the 

 Spring of 1908. Also Notes on the Imniigratory movemeuts 

 and Records received from Lighthouses and Lightvessels during the 

 Autumn of 1907. By the Committee appointed by the British 

 Ornithologist's Club. London, Witherby ^c Co., 1909, pp. 235, 

 29 Maps. Price 6^-. net. 



This Fourth Annual Report is of interest and value to English orni- 

 thologists, but owing to the absence of a summary of results, or a 

 comparison with previous Reports it is of little use to an Irish orni- 

 thologist. When a little more work would have made all the difference 

 in usefulness, it is a pity the Committee could not have arranged for the 

 extra labour. Perhaps they intend doing this every //V^ years, in which 

 case we shall look forward with interest to the next Report. vSir Boyle 

 Roche's celebrated remark about being in two places at once will now 

 have to be slightly modified to. " Barrin I was a Ring-Ouzel " ; this 

 species being announced as " arriving solJy in the western half of the 

 south-coast," and also as " arriving on the south-east coast " ; while to 

 add to the typical Hibernian flavour '• Lhe earliest records of this species 

 during the past four years have always come from Yorkshire." The 

 migration reports from lighthouses and lightvessels contain many 

 interesting observations.

BRITISH AND IRISH PROTOZOA. 



The British Freshwater Rhizopoda and Hellozoa. By the 



late James Cash, assisted by John Hoi'KINSON, F.L.S., F.Z.S., 



F.R.M.S. Vol. ii. Rhizopoda, Pt. 2. Loudon : Ray Society, 1909^ 



pp. xviii. and 166, with Frontispiece and Plates xvii.-xxxii. 



It is refreshing in these days, when Protozoology is bidding fair to 



rival Bacteriology in its purely medical development, to turn aside to 



this work, dealing with the shelled Rhizopods of lake, pool, and ditch. 



The well-devised plan of vol. i. is continued here. Analytical tables 



show the classification, and direct the student to minor groups. The 



synoptical descriptions of genus and species are clear and concise, and 



the detailed descriptions are full of interest. The figures are of quite 



exceptional beauty, the execution being unapproached by anything of 



the kind that we have hitherto seen in English publications. vSome of 



these have been contributed by Prof G. W. West. 



The present volume completes the shelled Lobose Rhizopoda ; the 

 Filosa and Heliozoa are left over for a third, concluding, volume. 



The work is introduced by its history narrated by ^Nlr. Hopkiuson. 

 the collaborator with the nominal author, though he modestly and 

 reverently contents himself with the title of assistant. Mr. Cash must 

 have been, like so many of the scientific amateurs who have distin- 

 guished English science, possessed of enormous patience and devotion
