128 ANNALS OF SCOTTISH NATURAL HISTORY 



make the rarer species more familiar and hence less liable to be 

 overlooked. G. G.-M. 



REPORT ON THE IMMIGRATION OF SUMMER RESIDENTS IN THE 

 SPRING OF 1908 : ALSO NOTES ON THE AUTUMN MOVEMENTS OF 

 1907. By a Committee of the British Ornithologist's Club. 

 London: Witherby & Co., 1909. 6s. 



This Annual Report is written on the same lines as those which 

 we have noticed favourably in past years, and hence it does not 

 call for an extended notice. It is to be commended to all those 

 Scottish naturalists who are interested in the subject, since it usefully 

 links up the details relating to their own country with that of 

 England. The report has grown in scope since its inception in 

 1906, and now includes records of " Unscheduled Species," and 

 " Notes on the Migratory Movements of the Autumn," and runs to 

 235 P a ges. 



THE BRITISH FRESHWATER RHIZOPODA AND HELIOZOA. By 

 the late James Cash, assisted by John Hopkinson, F.L.S., etc. 

 Vol. II. Rhizopoda, Part II. (London : Ray Society, 1909.) 



The first volume of this valuable monograph was published in 

 1905 (vide "Annals" for 1906, p. 127), and now we have the 

 second of the series of three in which it is being issued before us. 

 Owing to the lamented death of Mr. Cash on February 20, 1909, 

 shortly after he had finished writing out the descriptions of the 

 species and notes on distribution, the task of completing the MS., 

 and seeing the volume through the press, fell entirely on Mr. 

 Hopkinson. A proof, it is interesting to observe, was read by Dr. 

 Penard of Geneva, and Prof. G. S. West has contributed to the 

 illustrations. 



The present volume, which takes us to the end of the Arcellida, 

 deals with 14 genera (Difflugia to Zonomyxa), and Si species with 

 varieties, 13 of the species being new to science. These are fully 

 described in 166 pages of letterpress, and illustrated by an ample 

 series of excellent figures, mostly from Mr. Cash's own drawings, on 

 1 6 plates, 10 of which are coloured, with many text-figures besides. 

 The .synonymy and references to literature to end of 1908 entirely 

 the work of Mr. Hopkinson are very full. Under each species is 

 given a general statement as to the nature of the habitat, followed 

 by a fair number of localities in various parts of the British Isles, 

 including Scotland, both north and south. In all respects the 

 volume worthily upholds the high traditions of the Ray Society's 

 publications. W. E.
