266 THE SCOTTISH NATURALIST 



of a paper by James F. Gemmell on the development and 

 adult structure of the starfish Asterias rubens ; and a list of 

 recent additions to the local marine fauna, in which some 

 five-and-twenty species are referred to. 



Part XVII. of A History of British Mammals, by 

 G. E. H. Barrett-Hamilton and Martin A. C. Hinton, was 

 published in July last. It is almost entirely devoted to the 

 genus Apodernus, which is considered to include the following 

 six species : the Field Mouse, Hebridean Field Mouse, St 

 Kilda Field Mouse, Fair Isle Field Mouse, Yellow-necked 

 Field Mouse, and De Winton's Field Mouse. 



Two articles dealing with animal behaviour have recently 

 appeared in the pages of our contemporaries. Edmund 

 Selous, so well known for his observations on the courtship 

 of birds, etc., is publishing in the pages of The Nattiralist^ 

 an account of his " Observations on the Grey Seal " ; while 

 Maud D. Haviland contributes - a series of " Notes on the 

 Courtship of the Lapwing." But the pressure upon our 

 space forbids the summarising of these papers. 



Anna J. Reilly, of the Royal College of Science, Dublin, 

 has just published^ a paper which will prove indispensable 

 to students of the British Aptera. It is entitled " Notes 

 on the British Machilidia^, with Descriptions of Two New 

 Species." No fewer than five species of this family are now 

 recognised as members of our fauna, and these are referred 

 to the genera Pctrobius (four species) and Petromadiilis (one 

 species). With the aid of the synoptic table and the five 

 lithographic plates which accompany the paper the student 

 should experience little difficulty in determining any of the 

 " bristletails " of this family which fall into his hands. 



In the recently issued Proceedings of the South London 

 Entomological and Natural History Society for 1914-15, the 

 student of insect life will find several useful papers. The 

 Rev. G.Wheeler contributes a very readable account of the 



' July and August 1915.
