a human foible on occasion, and we trust that a lesson in humility is 

 gained for each of us:

 318. 



"For those who insist on dividing specifically specimens which may be the 

 progeny of a single pair, the above varietal names may take specific rank. For 

 myself, I believe, in the present state of science, that most stress should be laid 

 upon the relationship, rather than trifling points of difference, since in the 

 dust-cloud of names applied to every individual mutation, all general principles 

 become obscured."

"i wrote a description of this species and had the present figure prepared about 

 1892, but although I have a strong impression the diagnosis was published, I have 

 mislaid the reference to it and so give a brief description."

"In extenuation it must be remembered that fifty years ago the necessity of 

 strictly conforming to the rules was little appreciated, and many excellent 

 naturalists of that day are responsible through their carelessness for much of the 

 trouble now encountered." 



STATISTICS. The total number of names introduced by Dall and 

 included in this catalog is 5,427, of which 5,302 are molluscan and the 

 remaining 125 non-molluscan. This total is amazingly close to the 5,680 

 names introduced by Pilsbry (Clench and Turner, 1962). Had the 

 suprageneric names of Dall been included in this compilation, the total 

 would have been considerably greater and probably more nearly would 

 have approximated that of Pilsbry. 



The frequency with which certain names were used by Dall is 

 interesting because, at least in part, it reflects upon his associations and 

 the areas of his scientific concentration. Those names which were used 

 more than ten times are listed in the order of their decreasing frequency: 



chipolana -us (53); floiidcma -uin -us (33); califoniica -us (25); 

 pacified -us (23); panaiuensis (23); hawaiensis (21); alaskana -ensis (18); 

 stearnsii (17); caloosaense -is (16); gabhi -ii (16); oregonia -ense -ensis 

 (14); hurnsii (13); galapagcma -us (13); stimpsoni (13); hemlersoni (12); 

 mexicana -us (12); rhyssa (12); agassizii (11); aleutica -us {\\)\ diegensis 

 (11); hemphiliii (11); orcutti (II); palineri (11); precursor (11); rushii 

 {\\)\verrHlii{\\)\willcoxi{\ 1). 



ACKNOWLEDGMENTS. Dr. William J. Clench originally sug- 

 gested that this catalog of Dall's names be prepared and encouraged us 

 throughout its preparation. We are also indebted to the Milton Fund, 

 Harvard University, for a grant to help defray the cost of typing the 

 manuscript.
