present distribution of the liiglier animals over tlie surface of the earth. This 

 unclertaliing is stated to be based upon the result of original researches into 

 the zoological literatui'e of all countries. All the families of mammals, birds, 

 reptiles, and amphibians, together with several of the more important genera 

 and species, have been dealt with, and in addition most of the families of fishes 

 and a selection of families and genera of molluscs and insects. 



The text is divided into 5 parts. In part 1 (pp. 1-3) a short historical 

 account is given of the various systems propounded for the subdivision of the 

 world in zoogeographical regions, wherein the views of the leading authorities 

 are considered; in part 2 (pp. 4-12) the various regions and subregions of 

 Wallace are defined and an account given of their characteristic and peculiar 

 animals, with original tables, giving a numerical summary of the families of 

 terrestrial vertebrates occurring in these areas; part 3 (pp. 13-56), the main 

 portion of the text, is designed to afford concise information regarding the 

 groups of animals the distribution of which is shown on the plates. A census 

 based upon the latest information is given where possible of the number of 

 known species of each family. In part 4 (pp. 57-67) a bibliography is given 

 which contains a list limited to about 1,000 titles of the more important books 

 and papers dealing with the animals of the various regions. The titles are 

 arranged alphabetically under the authors' names, and are then grouped pri- 

 marily under the regions, and secondarily under the various classes of animals. 



The 36 plates embrace a series of 200 colored maps which illustrate the dis- 

 tribution of over 700 families, genera, and species of existing animals. A full 

 and comprelaensive index is appended. 



The mammals of the tenth edition of Linnaeus; an attempt to fix the 

 types of the genera and the exact bases and localities of the species, O. 

 Thomas (Proc. Zool. Soc. London, 1911, I, pp. 120-158). — The author states 

 that in preparing this paper Linnseus's quotations have been verified through 

 reference to the original works. 



On the common shrew mole (Scalopus aquaticus machrinus) in Illinois, 

 F. E. Wood {Bui. 111. State Lab. Nat. Hist., 9 (1910), Art. 1, pp. 1-13, figs. 2).— 

 Anatomical and bionomic studies of the species of shrew mole that occurs in 

 most of Illinois and throughout the eastern half of the United States are 

 presented. 



Collections made from different parts of the State indicate a gradual increase 

 in size from east to west, across the State. The investigations indicate but 1 

 litter a year, which is brought forth the latter part of April or early in May. 



In Illinois the chief complaint against moles has been that they destroy 

 recently-planted corn, in some cases it being said that 25 per cent of the first 

 planting has been destroyed. The author finds that moles work in corn fields 

 all summer and fall but the damage is practically all done within the first 

 10 days after planting. Experiments conducted during the season of 1908 with 

 repellents in which seed corn was treated with kerosene, carbolic acid, formalin, 

 oil of lemon, and other vegetable oils, failed to give definite results, except in 

 cases where the quantity used was so great as to injure the seed. 



Studies upon plague in ground squirrels, G. W. McCoy {Pub. Health and 

 Mar. Hosp. Serv. U. S., Pub. Health Bid. 43, 1911, pp. 7-5i).— These studies are 

 reported in 4 parts under the headings, (1) pathology and bacteriology of 

 plague in ground squirrels, (2) notes on induced plague in ground squirrels, 

 (3) immunity of certain squirrels to plague infection, and (4) insect transmis- 

 sion in relation to plague among ground squirrels.

 Agr., Bur. Biol. Survey Bui. 37, pp. 64, pis. 6, figs. 3).— This bulletin describes
