Long Beach supplies Donaw californicus, a favorite clam for soup. At 
low tide the long, sandy drive on the strand between Long Beach and 
New River, a fork of the San Gabriel, is diversified by a small pile of 
soft rock, known as Devil’s Gate, where afew rock Pholads are found. 
At the extreme south of San Pedro Bay is Alamitos, at the mouth of 
New River. Here are Crepidula, Cerithidea, Melampus, and Pecten. 
Laguna Beach, the home of Trivia, is 30 or 40 miles south, but in the 
recent division of Los Angeles County this beach was apportioned to 
the new county of Orange. 
About 25 miles out in the Pacific Ocean is a little island, one of the 
Santa Barbara Islands, known as Santa Catalina. This mountainous 
stretch of land is included in Los Angeles County. This island is 
almost 27 miles long, and from 4 to 8 miles wide save at the isthmus. 
It is “chiefly metamorphic rock,” and the beach is composed wholly of 
pebbles; many of these are a pure white. Collecting is confined to the 
small beaches that border the narrow valleys between the precipitous 
hills. Haliotis and Lucapina crenulata are found in the winter. In 
summer collecting is poor. Mr. Dall says, “The gravelly shores of 
Catalina Harbor on the south side are rich in small species.” 
In the following list, where the name of the bay is not given, San 
Pedro is intended. 
The author gratefully acknowledges the assistance she has received 
through the kindness of Mr. William Healey Dall, Dr. Robert E. C. 
Stearns, and Mr. Chas. T. Simpson, of the Smithsonian Institution, and 
J. G. Cooper, M. D., of the California Academy of Sciences, in the 
determination, with notes, of a number of shells. The species so iden- 
tified are, in each instance, noted by the initials in brackets of the 
gentleman to whom the species was referred. Mr. Dall has also kindly 
advised her relative to many changes in nomenclature, 
(W. H. D.)—Mr. William Healey Dall, National Museum. 
(R. E. C. 8.)—Dr. Robert E. C. Stearns, National Museum. 
(C. T. 8.)—Mr. Charles Torrey Simpson, National Museum. 
(J. G. C.)—J. G. Cooper, M. D., California Academy of Sciences: 
The shells on the list identified at the Smithsonian Institution by 
Mr. Simpson were for the most part collected by Miss Shepard. 
The number of southern shells lately added to the fauna of this vici- 
nity is so great that some suspicion has been aroused as to the possi- 
bility of some of them being adventitious, but they are included in order 
that the question as to their provenance may be kept in view, and in 
time definitely settled by the collection of living specimens.

| NoTE.—In advance of a general revision of the classification of the 
Californian mollusk-fauna it has been thought most convenient in this 
list to retain the familiar arrangement of the late Dr. Carpenter.—W.
