119. At the request of the Smithsonian Institution, Mr. Temple Prime, of 

 New York, well known for his special devotion to this department, has con- 

 sented to prepare a Manual of the Cyrenidae inhabiting American waters. 

 All the accessible materials from the West Coast are in his hands for exami- 

 nation. The first part of his " Monograph of the Species of Sphcer'mm of 

 North and South America" is printed in the ' Proc. Ac. N. Sc. Phil.' 1861, 

 pp. 402 et seq., and contains quotations of five species, nos. 4, 7, 9, 10, 11, 

 with synonymy, from Washington Ter., Oregon, and California. He has 

 kindly (in advance of his intended publications) furnished to Mr. W. G. Bin- 

 ney the following MS. " Synopsis of the Corbiculidae of the West Coast of 

 North America," with liberty to publish in this Report. It is here condensed, 

 with synonyms and references, in the nomenclature of the writer.
