ZOOLOGICAL TAXA OF WILLIAM HEALEY DALL 3 



Linne and would then supply a new name for B-us c-us of author 'A.' 

 Textually this renaming of a misidentification often reads as if it were a 

 renaming of a homonym, which of course it is not. It really is a description 

 of a new species based upon a misidentification. Although many of Dall's 

 names are valid renamings of homonyms, it has been difficult for us to 

 distinguish between true homonyms and the renaming of misidentifica- 

 tions. But in each case which is not simple homonomy, the new name ( = 

 new species) either requires a type-locality and type-specimen of its own 

 or assumes the data supplied by author 'A,' wherein the figured specimens 

 or hypotypes of author 'A' become primary types. In other cases, where 

 homonomy appears valid, Dall sometimes cited a type-locality and a 

 type-specimen; these are really invalid (see Palmer, 1958, p. 58). The user 

 will have to make his own interpretations in the cases we have been unable 

 to detect. 



Another problem is posed by the names contained in Carpenter's 

 unpublished monograph on chitons. Both Dall and Pilsbry used Carpen- 

 ter's manuscript names, and Pilsbry (1892) credited the names to 

 Carpenter; however, some of the specific and even generic names were 

 properly introduced into the literature by Dall. With the guidance of 

 Palmer (1958), we have attempted to credit Dall when he validly named a 

 taxon, even if he cited it as a Carpenter manuscript name. 



As has been the case with many prolific authors, Dall began some 

 works which, for various reasons, he did not complete. At times 

 manuscript names were assigned to specimens in the U. S. National 

 Museum, and some named lots were even distributed as duplicates. One of 

 his largest unpublished works was on the gastropods of Hawaii, and a few 

 of the names in this manuscript have appeared in print. Since it is hoped 

 that the present catalog is complete for all species validly described by 

 Dall, it is to be expected that a name not included here was not published 

 by him. Nevertheless, the chance of error in any compilation of this 

 magnitude warrants the exhausting of every possible avenue for checking 

 the validity of a Dall name before regarding such as only a manuscript 

 citation. In this regard, the researcher is warned to exercise caution, 

 especially where Hawaiian species are concerned. Further, we fully expect 

 that some valid names of Dall will be discovered after the publication of 

 this catalog. 



No one can peruse the works of Dall — even glance briefly at his 

 monumental bibliography — without marveling at the man who produced 

 them. During the compilation of this catalog, although truly impressed by 

 the profound knowledge and incredible output of an author who created 

 such masterpieces as the "BLAKE Report" and the "Tertiary Fauna of 

 Florida," we have gleaned a number of quotations which, at the vantage 

 point of more than half a century, may cause the reader a slight grimace of 

 humor. We present these with the hope of showing that even Dall exposed
