The treatment adopted in the present work is very similar to that 

 employed by the author when dealing with the Pelecypoda in a previous part. 

 Here, however, numerous extracts and figures from Pilsbry's work, add 

 greatly to the general value. 



Mr. Baker, in nearly all cases, has given very clear descriptions of the 

 shell, the animal, jaw, radula, and notes on the generative organs, distribution, 

 and habitat. 



Referring to the speed of molluscs while in motion, the author gives 

 the results of some of his own observations. A few species were timed whilst 

 travelling a distance of two inches, with the following results : — 



Liinnaca paliistvis 

 Limnaca caperata 

 Limiiaca ciibcnsis 

 Limnaca rcflexa 

 Physa Jietei'ostroplta 

 Vivipara coiitcctoidcs 



In a work of this character, an author has often to rely upon the state- 

 ments of other writers, and in consequence it behoves him to exercise every 

 care and discrimination in selecting the same. The statements found on p. 

 197 re Liniax maxiiiiits, L., are woefully inaccurate ; it reads : — " In Europe it 

 is solitary in habit and is found chieHy in the woods, under fallen trees and 

 stones and near the sea shore. . . Its food consists principally of fimgi. It is 

 said to rarely to eat green plants (vide Scharff)." Owners of vegetable gardens 

 know to their cost how very plentiful this species is, and what damage it does 

 to the produce. 



In all 113 species are recorded comprised in 38 genera. The volume 

 concludes with a useful Bibliography, Glossary, an Appendix, Index, and 9 

 plates.
