120 JOURNAL 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 employed; 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 Unionoidee, 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!
