128 ANNALS OF SCOTTISH NATURAL HISTORY 



We understand that the second volume, on Butterflies, will be 

 published in twenty parts at one shilling each net. This method of 

 publication should enable any one at all interested in the subject to 

 procure the work without feeling the expense. P. H. G. 



THE BRITISH TUNICATES ; AN UNFINISHED MONOGRAPH BY 

 THE LATE JOSHUA ALDER AND THE LATE ALBANY HANCOCK, 

 F.L.S. Edited by John Hopkinson, F.L.S., F.G.S., Secretary of 

 the Ray Society. Vol. ii. With lives of the Authors by Canon 

 A. M. Norman and the late Dennis Embleton. London : Ray 

 Society, 1907. 



Never in the whole course of its long career of usefulness has 

 the Ray Society been doing better work for British Naturalists than 

 during recent years. Through its benign agency a number of 

 singularly valuable and much-needed monographs have been issued, 

 which, in all probability, would not otherwise have seen the light 

 on account of the expense involved in their production. The 

 volume for 1907 is the second of the unfinished work on British 

 Tunicates by two great masters on the subject, both, alas, no longer 

 with us, but concerning whom biographies are furnished by con- 

 tributors most competent to write them. The volume is illustrated 

 by thirty plates, chiefly coloured, and has been edited by Mr. John 

 Hopkinson, to whom we offer our congratulations on the excellence 

 of this latest production of the Ray Society. 



ILLUSTRATED HANDBOOK TO THE PERTHSHIRE NATURAL 

 HISTORY MUSEUM, AND A BRIEF GUIDE TO THE ANIMALS, 

 PLANTS, AND ROCKS OF THE COUNTY. By Alex. M. Rodger, 

 Curator. Second edition. Perth: The Society, 1906. Price 3d. 



This is an excellent little guide to the collections of the Perth 

 Museum, which is one of the best arranged local institutions of 

 its kind in Great Britain. It treats mainly of the fine series of 

 specimens illustrating the Fauna, F'lora, and Geology of the extensive 

 and varied surface of the County of Perth ; affording in a series of 

 annotated lists much information in brief on the Perthshire mammals, 

 birds, reptiles, amphibians, fishes, plants, trees, fungi, etc. ; and also 

 an enumeration of the rocks and minerals. Another section is 

 devoted to the Index and Type Collections, concerning which it 

 gives reliable and appropriate information for the use of the visitor 

 to the general collections to be seen in the Museum. It is a neat 

 and well-illustrated Handbook, and reflects great credit on the 

 Curator, Mr. Alexander M. Rodger ; and the Society is to be con- 

 gratulated on its all-round excellence, and its usefulness not only 

 in the Museum, but outside of it.
