Unknown to Dr. Cooper, Dr. Palmer sent a valuable consignment of the 
shells collected by the Survey between San Diego and 8. Pedro to the Smith- 
sonian Institution, without acknowledgment of their source. They would 
have been described and erroneously assigned to his credit, but for the tardy 
and accidental discovery of their origin. Dr. Cooper obtained permission to 
send the first series of duplicates, duly numbered, for identification, to the 
Smithsonian Institution. This invaluable series was lost in the “ Golden 
Gate.” The gold was recovered, and much of it stolen ; the far more precious 
shells remain, unnaturally located, in their native element—a puzzle, perhaps, 
to palontologists in some coming age. Other series, though not so com- 
plete, have since been received in safety ; and through the liberality of the 
Californian Survey and of the Smithsonian Institution, as well as through the 
energy and kindness of Dr. Cooper, they are already being distributed to the 
Cumingian Collection, the British Museum, the museums at Cambridge, 
Mass., Philadelphia, Albany, Montreal, &c., as well as to the collections of 
working naturalists. The stations being now discovered, it is to be hoped 
that in a few years Californian shells will cease to be objects of great rarity 
in this country. At the request of Dr. Cooper, in order that he might pro- 
ceed with other departments of his labours, all the new species which have 
been seen in England have been described in conjunction with those from 
other sources. On those which are only known here by the beautiful drawings 
sent by the collector, it would be unsafe and premature to impose a name. 
The diagnoses are being published in the Proc. Cal. Ac. N.8., and should be 
accredited to the zealous zoologist of the Survey, rather than to the mere 
artist-in-words who endeavours to represent their forms to the reader. It 
will be understood that the lists now to be presented, though corrected to the 
date of going to press, are still incomplete; and that the information has been
