Dr. Palmer sent a valuable consignment cf shells collected by him between 

 San Diego and S. Pedro to the Smithsonian Institution. Dr. Cooper obtained 

 permission to send the first series of duplicates, duly numbered, for identi- 

 fication, to the Smithsonian Institution. This invaluuble scries 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 palaeontologists in some coming age. Other series, though 

 not so complete, have since been received in safety; and through the libe- 

 rality of the Californian Survey and of the Smithsonian Institution, as well as 

 through the energy and kindness of Dr. Cooper, they are already being dis- 

 tributed to the Cumingian Collection, the British Museum, the museums at 

 Cambridge, Mass., Philadelphia, Albany, Montreal, &c., as well as to the col- 

 lections of working naturalists. The stations being now discoveied, it is to be 

 hoped that in a few years Californian ehells will cease to be objects of great 

 rarity in this country. At the request of Dr. Cooper, in order that he might 

 proceed 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 

 Bent by the collector, it would be unsafe and premature to irajMse a name. 

 The diagnoses are being published in the Proc. Cal. Ac. N. S., 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 correctrd to the 

 date of going to press, are still incomplete; and that the infurmatiuu has beca
