A Preliminary List of Shells from Laguna 

 Beach and Nearby 



For a number of years past students ha\e collected shells from 

 Laguna Beach, these and the Bradshaw collection form the basis 

 for this list, which includes shells not farther than ten or twelve 

 miles up and tl()\\n the coast. The earlier collections were by 

 Mabel Guernsey and P. R. Daggs. Practically all the shells drawn 

 and photographed are from the Bradshaw collection because the 

 shells were in better condition. Some of the earlier specimens were 

 determined by the United States National Museum. Suggestions and 

 corrections were kindly made by Mrs. T. S. Oldroyd. The photo- 

 graphs are by Robins and Cooper. Many of the drawings are by 

 Miss Margaret Cate. Doubtful specimens are large omitted in this 

 list, but a few are included and marked by a question.
