58 THE JOURT^^AL OF BOTANY 



Ophrys NEOCAiSfFSTi iiom. 110 V. When I gave the name x OpJnys 

 olhiensis to the hybrid 0. araclinitiformis Gren. et Phil. X O. Ber- 

 tolonii Moret (Journ. Bot. 1914, 271), I was not aware that this 

 name had ah'eadj^ been applied to another hybrid Oplirys^ O, homhi/- 

 lifiora Link. X O. scolopax Cav. (Camus, Mon. Orch. Europe, p. 3C)G, 

 1908). I therefore now replace it b}^ x Ophrys neocamtisii, in 

 honour of Mdlle A. Camus, joint author of the monograph quoted 

 above and responsible for the anatomical detail of that work, in 

 recognition of her great and numerous services to botanical science. —

REVIEWS. 



A Catalogue of British Scieiitijlc and Technical Books. Covering 

 every Branch of Science and Technology carefully Classilicd and 

 Indexed. Prepared by a Committee of the British Science Guild, 

 6 John Street, London, W.C. 2. 8vo, cloth, pp. xviii, 370. 

 Price 10s. net. 



The object of this handsome, well-printed volume is to supply *' a 

 complete record of scientitic and technical books other than those 

 intended for primary schools, and elementary volumes of like nature, 

 in the current lists of publishers in the United Kingdom, and obtain- 

 able through booksellers in the usual way." The aim of the Catalogue, 

 although somewhat ambiguously expressed, is admirable ; as, from a 

 bibliographical standpoint, is its execution ; the classification of the 

 titles — more than six thousand in number — if a little complicated, is 

 rendered easily accessible b}^ the list of contents ; there is a very 

 complete " name index," extending to fifty pages, as well as one of 

 subjects : in all these important details the Catalogue could hardly 

 be more satisfactory ; moreover, it is admirabl}^ printed, in double 

 columns. 



The preface makes special mention of the help afforded by Mr. 

 P. Passenger, one of the Committee, "who not only possesses wide 

 knowledge and long experience in the handling of books on science 

 and technology, but is also keenly interested in the cataloguing of 

 them." It is, however, judging from the section on Botany, with 

 which alone we are concerned, in books on science that the Catalogue 

 is weakest ; this indeed might be anticipated from the composition of 

 the Committee, in which biologists are hardty represented. In Botany 

 proper — Forestry and Palaeontology are separately treated, — which 

 occupies ten pages, a number of useful and standard works are cata- 

 logued, but it is not easy to discover on what principle the selection is 

 made. The first entry, for example, is B. A. [H.] Alcock's Botanical 

 Names for English Readers, which, published in 1876, is certainly 

 not in " current lists of publishers," and although it stands under the 

 heading " General," can hardly be regarded as '' Botany." The 

 entries under " General " should have been grouped ; we find among 

 them De Bary's Bacteria, though there is a section on Bacteriology. 

 Under " Algie," none of the works save G. S. West's Cambridge
