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 Amnicolidas that haye not been 

 sorted out. And the same is true of a very large amount of 

 Ancylidx from the Coosa and its tributaries. 



" But it was especially in the Pleuroceridce 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 Anculosce 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. 



"I 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:
