CATALOGUE 



OF 



BELONGING TO THE 



Order PHOLADACEA. 



By GEORGE W. TRYON, Jr. 



The following Catalogue is compiled principally from a work published by 

 me in 1862, entitled " Monograph of the Order Pholadacea, and other Papers,"* 

 to which the student is referred for full synonymy, descriptions and remarks, 



The species published since the issue of this work, have all been included 

 in the present list, and a few changes have been made in nomenclature and 

 synonymy, the result of a more mature consideration of the subject. 



One hundred and forty species are admitted as valid, and the synonymy 

 embraces several hundred more.
