he had struck a remarkably rich region. Then a ‘‘Syndicate”’ 
was formed of T. H. Aldrich, of Washington, D. C., Mr. 
Bryant Walker, of Detroit, Dr. H. A. Pilsbry, of the Academy 
of Natural Sciences, Phlladelphia, Pa., and the writer, and the 
work was carried on steadily for over six years. Dr. Pilsbry 
dropped out in 1906, and he was replaced by Mr. John B. 
Henderson, of Washington, D. C. 
The naming and distribution of the thousands of land shells 
collected in all parts of Alabama, fell to the part of the writer, 
and the new species have all been described by him; 13 species 
and 4 varieties up-to-date, with probably several more to follow, 
as the material is more carefully studied. After the regular 
work for the ‘‘Syndicate’’ was stopped, Mr. Smith continued 
collecting fresh-water shells for Mr. Walker, and land shells for 
the writer, while collecting Tertiary fossils for the Geological 
Survey of Alabama, by which he was employed as Curator of 
the Museum at the University of Alabama. The sorting, 
naming and distributing of the fresh-water shells, was done by 
Mr. Walker, and I cannot do better than quote from a letter 
from him, on this subject: 
‘‘T enclose the meager list of n. sp. and vars. that have been 
described from Mr. Smith’s material. But that does not begin 
to show the enormous amount of work that he did in develop- 
ing the fauna of Alabama. Besides going the whole length of 
the Coosa from Gadsden to Wetumpka by boat, he did the 
Black Warrior thoroughly before it was spoiled by the Govern- 
ment improvements (?) and spent a season on the Mussel Shoals 
of the Tennessee. Two or three summers were spent on the 
Connasauga and other head-waters of the Coosa, and in numer- 
ous side trips he had covered practically the whole state. 
Then, too, through local collectors, many of them trained by 
him, he had reached into many localities that he did not per- 
sonally visit. By these means he collected an enormous 
amount of material, practically none of which has been worked 
‘‘While he worked for the ‘Syndicate’ he collected every- 
thing; but when that arrangement ceased, he specialized in the 
Unionidz and Pleuroceride. I have not any very accurate fig- 
ures on the number of specimens of Unionidz that he collected, 
but I think that from 40,000 to 50,000 would not be an over- 
estimate. His Black Warrior collection alone he reported as 
10,000. No report on this material has ever been made, and a
