(5) teeth, (6) illustrations (skull and teeth), 

 and (7) key to the European forms. The 

 synonymy is given only under the several sub- 

 species, which are each diagnostically de- 

 scribed, with measurements, a statement of its 

 range, the sources and amount of material ex- 

 amined, and a list of the specimens contained 

 in the British Museum. The descriptions of 

 the subspecies occupy 14 pages, an average of 

 a little more than a page to each, while the 

 tables of cranial measurements fill four addi- 

 tional pages and include a total of 103 skulls, 

 with 11 measurements of each skull. 



(6) Resources and Results. — Although three 

 of the here accepted subspecies of Sciurus vul- 

 garis date from the eighteenth century, and 

 two others from the early part of the nine- 

 teenth, none had become authoritatively recog- 

 nized as tenable forms prior to 1896,^ so that 

 of the twelve forms now admitted six have 

 been described and five others established 

 since 1904. All but three of the 12 recognized 

 forms are represented by fair series of speci- 

 mens (5 to 174), the material examined ag- 

 gTegating 512 specimens. A list of the ac- 

 cepted forms, with their ranges and the num- 

 ber of specimens of each examined, here fol- 

 lows: 



1. Sciurus vulgaris vulgaris Lhrnfi, 1758. Scan- 



dinavian Peninsula, except extreme north. 

 Specimens examined, 53. 



2. Sciurus vulgaris varius Gmelin, 17S9. Extreme 



north of Scandinavian Peninsula, east into 

 Russia. Spec, ex., 8. 



3. Sciurus vulgaris leucurous Kerr, 1792. British 



Islands. Spec, ex., 174. 



4. Sciurus vulgaris russus Miller, 1907. West- 



central Europe. Spec, ex., 26. 



5. Sciurus vulgaris fuscoater Altum, 1876. East- 



central Europe. Spec, ex., 170. 



6. Sciurus vulgaris italicus Bonaparte, 1838. 



Italy. Spec, ex., 38. 



7. Sciurus vulgaris Ulce^ts Miller, 1907. Greece. 



Spec, ex., 3. 



8. Sciurus vulgaris alpimis Desmarest, 1822. 



Pyrenees. Spec, ex., 2. 



9. Sciurus vulgaris ixumaniius Miller, 1907. 



North-central Spain. Spec, ex., 22. 

 'Nearly a dozen others of early date, proposed 

 as ' ' varieties, ' ' have never had currency, and are 

 treated by Miller as untenable. 



10. Sciurus vulgaris infuscatus Cabrera. Central 



Spain. Spec, ex., 5. 



11. Sciurus vulgaris segurcB Miller, 1907. South- 



Tvest Spain. Spec, ex., 11. (Probably same 

 as the next.) 



12. Sciurus vulgaris hceticus Cabrera. Southern 



Spain. Spec, ex., 0. 



In general method and in details of treat- 

 ment the " Catalogue " may well serve as a 

 guide and an inspiration in similar undertak- 

 ings. It furnishes for the first time a solid 

 and orderly foundation for further systematic 

 work on the mammal fauna of the area 

 treated. Although the author's conclusions 

 can not safely be challenged except on the 

 basis of equal or better opportunities for in- 

 vestigation, doubtless some forms have been 

 accepted that further study will show are not 

 well founded, while others probably remain to 

 be discovered. Finally, it is pleasant to con- 

 template the combination of circumstances 

 that led to the preparation and publication of 

 the work through a combination of the re- 

 sources of two great national museums, and 

 by an author so eminently fitted for the task.

Malaria, Cause and Control. By William B. 

 Herms. New York, The Macmillan Com- 

 pany. 1913. Pp. si -\- 163. 

 The purpose of this little work is to awaken 

 the public interest in the control of malaria 

 through the control of mosquitoes. Its ap- 

 pearance at this time is opportune, as, no 

 doubt due to the example and influence of 

 Celli in Italy, there has been a growing senti- 

 ment in many quarters in favor of the control 

 of malaria by the extensive administration of 

 quinine. Quinine control has not only proved 

 impracticable under many circumstances, but 

 under rigorous tests — particularly in the 

 tropics — has even failed altogether. Professor 

 Herms's book is based upon California experi- 

 ence and addresses itself directly to Cali- 

 fornians; but in so far as similar conditions 

 obtain elsewhere, it should have a much wider 

 field of usefulness. The treatment is elemen- 

 tary throughout. A large part is devoted to 

 the practical side of mosquito control.
