INTRODUCTION 



he following catalogue covers all of the new names created by Henry Au- 

 gustus Pilsbry and his several co-authors, for both Recent and Fossil forms in the 

 Mollusca and Crustacea. These names range in taxa from those above the family 

 level to subspecies, varieties and forms. 



This work had its inception many years ago when we found it necessary to 

 "card out" the new names which Pilsbry had instituted so that these names 

 might be used in our own current problems of research in the field of malacology. 

 As time went on, this catalogue increased in size and became a source of ready 

 information to all members of our staff. Its completion and publication we 

 felt " would make available a large file of data not easily located elsewhere. 

 Although the "Zoological Record" has listed most of Pilsbry's names, searching 

 through it is a slow process because 5,680 names were introduced by Pilsbry 

 over a period of 75 years. Furthermore, many private and institutional Hbraries 

 do not have a set of the Zoological Record. 



In carrying out such a task, one learns much about certain facets of a man's 

 character. Pilsbry, in a measure, isolated himself. Few, if any, reviewed his 

 manuscripts before they went to press and consequently many minor errors 

 escaped the editor. Most of these were errors of omission rather than com- 

 mission. For about fifty percent of his specific and sub-specific names he gave 

 no type number for the specimen or specimens used in his descriptions. Most 

 of these type specimens are in the collections of the Academy of Natural 

 Sciences of Philadelphia. The introductory remarks in any one paper, however, 

 usually indicate in which institution the types are located. 



In names above the generic level he frequently left out any indication that 

 they were new, and it has been a diflBcult task to determine the first introduction 

 of such names in this category. Also, authorship of many was rarely mentioned 

 and it is certain that we have missed some of these. 



There is Httle doubt that Pilsbry introduced more names tlian any other 

 student in the field of malacology. Probably only W. H. Dall even approxi- 

 mated the number created by Pilsbry.
