THE NAUTILUS. 139 
very large proportion of it still remains to be worked over. 
This I shall do as rapidly as I have time. I also have on hand 
many thousands of specimens of Amnicolidx that haye not been 
sorted out. And the same is true of a very large amount of 
Ancylidz from the Coosa and its tributaries. 
‘* But it was especially in the Plewrocerid@ that he put in his 
best work. He became exceedingly interested in that family 
and the many perplexing problems that its protean species pre- 
sented, and it was his expectation to work it up himself. The 
enormous collection, thousands upon thousands of specimens, 
and the familiarity that he had acquired in his many years of 
field work, especially fitted him for the work. But unfor- 
tunately the multitude of duties that pressed upon him, as 
Curator of the State Museum, prevented him from carrying his 
plan into execution. He had planned to publish a paper on 
the Anculose of the Coosa for some time, and expected to write 
it up this last spring. He had gone so far as to arrange a series 
of the species in the order that he intended to present them, 
but his untimely death prevented the completion of the work. 
Beyond this, and a somewhat similar arrangement of the 
Gyrotomas, nothing has been done and, except the manuscript 
names attached to many species that he believed to be new, and 
which he intended to describe, there is absolutely nothing left 
to show the vast knowledge that he had acquired of that mar- 
velous fauna. He had it all in his brain, and it all perished 
with him. I do not suppose that any other man ever had such 
an intimate knowledge of the variation of that family, and to 
think that it is all gone, is truly pitiful. 
‘*T do not believe that the fauna of any other State in the 
Union has ever been so thoroughly worked as was that of Ala- 
bama, by him.’’ 
I do not know how many new species were collected by Mr. 
Smith in Brazil, the West Indies and Mexico, but the follow- 
ing is the list from Colombia and Alabama:
