INTRODUCTION 



This report on Pilsbry's names is concerned only with their initial introduc- 

 tion. It is to be noted in many cases no figures were given. This is true for 

 many species which he first described in the early issues of the "Nautilus." Most 

 of these species were figured later, mainly in the Proceedings of the Academy of 

 Natural Sciences of Philadelphia, shortly after they appeared in the "Nautilus." 



Many species described from Japan by Pilsbry alone or by Pilsbry and Hirase 

 jointly in the Academy Proceedings and in the "Nautilus" were later figured in 

 the "Conchological Magazine" (Kyoto, Japan, 1907-1915). This magazine was 

 edited and published by Y. Hirase. 



Pilsbry and Johnson published a report on the "New Mollusca of the Santo 

 Domingo Oligocene" (1917, Proc. ANSP 69: 150-202). None was figured. Most 

 of these species and subspecies were figured and published by Pilsbry (1922, 

 Proc. ANSP 73: 305-435) in a revision of the first report. 



Most of Pilsbry's species of land mollusks of North America are figured in 

 his monumental work covering this fauna (1939-1948, Land Mollusca of North 

 America, Mono. no. 3, Academy of Natural Sciences, Philadelphia, 1: 41 + 994, 

 figures 580; 2: 53 + 1113, figures 585). 



Pilsbry described a multitude of species from the Japanese Empire. In 

 many cases he did not differentiate between Japan proper and the many islands 

 and island groups distant from the main Japanese inlands. Also, he used 

 several different forms of spelling for the islands southwest of Japan, such as 

 Loo Choo; Riu Kiu and Ryu Kyu; all, of course, refer to the same island group. 



Pilsbry seldom gave a bibliography or a list of references in his papers. In 

 this regard, he considered the synonymies under the various species as a bibliog- 

 raphy. Care must be taken not to treat many of the names cited in the synon- 

 ymy as synonyms but rather as references, since he considered many of these 

 as subspecies or varieties and dealt with them as such, in the same paper. In 

 this particular procedure, he is nearly unique, at least in the field of Malacology. 



We have made no attempt to institute new names for any of the few homo- 

 nyms which Pilsbry created. Some he corrected, and very probably other work- 

 ers have made the necessary changes. This also holds true for the few genera 

 and subgenera in which he failed to designate a type species. We will not 

 attempt to supply by "subsequent designation" a type species, as this may have 

 been done by others or can be done by others when this problem must be 

 solved in their own research studies. 



We will be most grateful to anyone who can supply names which we have 

 overlooked, or point out errors of any kind which we have committed. Such 

 additions or corrections will be published later to supplement this present work.

Five new species and varieties are described and figured in this paper, all 

 credited to Carlos de la Torre. These are, however, manuscript names of de la 

 Torre and this paper is here considered as a joint effort of de la Torre and H. 

 A. Pilsbry. 



It is exceedingly unfortunate that Carlos de la Torre had given actually 

 hundreds of names to species or subspecies which were never described. Many
