New York, well known for his special devotion to this department, has con- 
sented to prepare a Manual of the Cyrenide 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 Spheriwn 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 Corbiculide of the West Coast of 
North America,” with liberty to publish in this Report. Itis here condensed, 
with synonyms and references, in the nomenclature of the writer.

tive, is scarcely fitted to displace long-used generic appellations in marking the family- 
group.
