found differ very slightly from the type form, described and figured by 

 Van Heurck, the margin of the valves being parallel, instead of having a 

 median constriction. In other details they are true to the type, though 

 somewhat shorter. Navicula alpina, the only diatom in West's book 

 endorsed raye. As its specific name implies it is usually found at a much 

 greater altitude than Martin Beck, which is only about 100 ft. above 

 sea-level. Navicula (sp. nov.) ; this is not given in Van Heurck's 

 Diatomacese, nor in Clue's Nat. Diat. It is, however, in Schmidt's Atlas 

 43/24, without a name, although the stauras (central vacant space) is 

 there shown slightly more distinctly than in Mr. M. H. Stiles' photograph 

 of it. This species will shortly be described in The Naturalist. Navicula 

 pusilla, a very beautiful diatom not previously recorded for v.c. 63. Only 

 specimen was met with — a complete frustule, the upper valve of which one 

 is slightly broken, though the lower is perfect. The genus Eunotia is 

 represented by 15 spp., next to Navicula the most numerous.

Tommy Smith at the Zoo, by Edmund Selous. London : Methuen 

 & Co., 183 pp., price 2/3 net. "This book is by our contributor, who is 

 the author of ' Tommy Smith's Animals ' and ' Tommy Smith's Other 

 Animals,' each of which has been published in several editions. It is 

 written in a happy conversational style, and deals with the lion, bear, 

 boar, kangaroo, elephant, orang-outang, penguin and ostrich. It is well 

 illustrated, and the book is likely to be as popular as its predecessors. 



Glossary and Notes on Vertebrate Palaeontology,* by S. A. Pelly. 

 London: Methuen & Co., 113 pp., Sh riet. During frequent visits to the 

 Natural History Museum, South Kensington, the author made notes on 

 the names of the various vertebrate remains there exhibited ; these he 

 extended by the aid of well-known text books, and the present volume is 

 the result. It contains about 700 scientific names of vertebrates, with 

 details of their origin and notes on the species described, and their geological 

 history. The notes have apparently been carefully compiled and will 

 doubtless be of great service to the visitors to the Natural History Museum, 

 to whom the names attached to the fossils are often anything but in- 

 telligible. The glossary will also prove valuable to the student of geology. 

 So far as we have tested the glossary we have found it quite good and re- 

 liable. 



The Herring : its Effect on the History of Britain, by Arthur Michael 

 Samuel. London : John IMurray, 200 pp., 10/6 net. We learn from 

 the publisher's announcement that ' This is not a Natural History book, 

 or a treatise on the Herring trade. It tells the story of an ancient industry 

 over a period of a thousand years. In the early jNIiddle Ages the Herring 

 created the wealth of the Hansa League, and, later, of the Dutch ; it was 

 for centuries the pivot of trade in Northern Europe. Out of the Dutch 

 Herring Fishing Fleet grew their mercantile marine, to be superseded by 

 ours in and after Cromwell's days. This was followed by the development 

 of the British Colonial Empire and the expansion of our sea-carrying trade. 

 The book deals with the 17th Century disputes around the Herring Fishery 

 and the Dominion of the Seas, and endeavours to throw light on what 

 Germany means by the phrase " The Freedom of the Seas." It contains 

 a number of curious and forgotten recipes for cooking the Herring.' The 

 author, at one time Lord Mayor of Norwich, has done his work thoroughly, 

 and makes an interesting contribution to British economical history. 

 The volume is well illustrated by reproductions of medals and old prints, 

 and there is a good Bibliography. There is naturally a strong Norwich 

 flavour to the work.
