“Frank H. Lattin, of Albion, Orleans Co., N. Y.,a dealer in natural history specimens, 
instruments, supplies and publications of all kinds. Every A. A. Chapter should have a copy of 
his complete catalogue and price-lists before making purchases. His specimens are the very 
best, and his prices will be found to be much lower than those of any other reliable dealer.’’ 
The above we copy from Three Kingdoms, the Hand-Book of the Agassiz Association. Our 
readers would no doubt save money by complying with this advice.

The undersigned has recently returned from the coast of Lower California with a good series 
of shells, and will spend the summer and fall on the northern coast of the Pacific States, and in 
the mountains of Idaho and the interior in the interest of Conchology. On his return he will 
publish a new Catalogue and Price List of his North American Shells. It will contain the names 
of nearly two thousand species and varieties, all collected by himself personally. Conchologists 
who contemplate adding American shells to their collections will find it to their advantage to de- 
fer purchasing until the Catalogue is ready for distribution; notice of which will be given in this 
ournal, 
: It will contain the names of many rare species and varieties; the material will be good, and the 
prices low. HENRY HEMPHILL, P. O. Box, 1023, San Diego, Calif.
