take up the largest portion of the catalogue, extending from page 204 to page 364, 

 892 galls being mentioned under this family. Of course this includes the same 

 gall-forming animal more than once on different genera and species of the 

 same family. Amongst the gall-forming animals catalogued we find not only 

 insects and mites, but also the parasitical Anguillulidre or Eelworms. 



It is interesting to note the occurrence of the knot-root eelworm {Heterodera 

 radicicola Greff) on Alliaria officinalis, the garlic mustard, so frequent in Southern 

 England, and on Lepidium sativum, one of the cresses. 



There are numerous figures of galls, which will prove a help to students. 



The references do not seem to be anything l'ke complete, which is a pity in a 

 valuable work of this kind. 



The nomenclature of most recent date is wisely adopted ; but it would have been 

 of great help if the various synonomic generic and specific names had been given. 



The catalogue, in spite of such minor defects, is a most valuable contribution to 

 zoological literature, and must ; be especially welcome to the economic biologist. 



There is a frontispiece, with portraits of Olivier, Bosc, Schlechtendal, and 

 Thomas, and there are 824 figures in the text. 



The work is published by A. Hermann, Rue de la Sorbonne, Paris, and the 

 subscription for the two volumes is 40 francs.

A Manual of Elementary Forest Zoology for India. By E. P. Stebbing, 

 F.L.S., F.Z.S., F.E.S. [Pp. 229 + xxiv. and 422 figures.] (Calcutta, 1908. 

 15J.) 



This most useful volume has been primarily drawn up as a manual for the use of 

 the students at the Imperial Forest College at Dehra Dun. We venture to think 

 it will serve a very much wider purpose and will be used as the standard work by 

 all who study the subject of Indian forestry or who have work in that depart- 

 ment. 



The manual covers all the animal kingdom from the protozoa upwards, but the 

 part dealing with these minute animals (of no arboricultural importance) and 

 others such as tape-worms, etc. are merely mentioned in the first chapter on " The 

 Scheme of the Animal Kingdom." Chapter II. is devoted to a systematic 

 examination of the Phylum Arthropods ; several additions we hope to see 

 included here in a future edition. There is no mention made of Eriophyidce^ 

 Oribatidce, and other acari which may be found of economic importance when 

 more is known of the forest pests of India. 



A chapter is given on the general character of insects. Needless to say, these 

 animals claim the major part of the work, extending from page 23 to page 167. 



The life-histories are given in small print, at least such as are known, and here 

 and there treatment and remedies are mentioned in notes. Practically all the 

 known common forest insects are dealt with and are well illustrated. We notice 

 some errors in the names, however. For instance, on plate XXIX. and page 88 an 

 Anthrenus and its larva is described as Dermestes vulpinus, and on Plate LXIV., 

 fig. 285, a male and female Anopheles are quite in error, and are apparently a 

 Toxorhynchites. Amongst such a large amount of information given one is sure 

 to find some errors and slips. 



Chapter XII. onwards deals with vertebrate animals. Numbers of snakes, 

 birds, and mammals of direct or indirect importance to the forester are figured and 

 briefly described, sufficiently, however, to enable the forest student and forester to
