120 JOUBNAL OF ENTOMOLOGY AND ZOOLOGY 



Coast from San Diego to Seattle, with his bicycle, in search of 

 shells; investigating every puddle, pool, pond, lake, ditch, 

 stream and river in his trips. He has collected material in 

 large quantities and then studied it in the laboratory; so from 

 training and experience he is more capable of writing on the 

 fresh water shells of this coast than anyone. This, the most 

 extensive of his published papers, is full of original ideas, and 

 numerous suggestions. He first gives the boundaries of the 

 California province in detail, then the composition of the fauna 

 as found in the paleontological history of the region; thirdly, 

 the classification em])loyed; fourthly, the new term Syntonia is 

 explained in detail; then lastly, taking up most of the paper, 

 the synopsis of species, in which the groups from the super- 

 family to species are defined. There is a full bibliography and 

 synonymy for the genera and species ; a table showing the Evo- 

 lutionary Cycle of the Unionoideae, and a summary and range 

 in time of the Californian fauna, and concluding remarks. 



Of course, a student with such radical ideas, a progressive, 

 could not escape the fire of one or more of the conservative 

 men ; and this is just what happened in a recent number of The 

 Nautilus. If you wish to smile, just look it up !
