A CENTURY OF ZOOLOGY IN INDIANA. 201 



others he always exchanged his fine common fishes for the smallest and to 

 them most indifferent-looking, when he recognized some new species or 

 even variety." 



Two of our most common turtles, the Map Turtle {Malacoclemmys 

 geographicus) and the Soft-shelled Turtle (Aspidonecles spinifer) were de- 

 scribed by Le Sueur. 



Dr. Eigenmann has called my attention to an article by the late French 

 naturalist Vaillant, "Note sur L'Oeuvre Ichthyologique de C. A. LeSueur," 

 in the "Extrait du Bulletin de la Societe Philomathique de Paris, tome VIII, 

 No. 1, page 15, 1895-1896." 



Vaillant states that LeSueur. after having returned to France from the 

 expedition to Australia in 1804 and after having aided in the publication 

 of the first volume of the narrative of that voyage, accompanied William 

 Maclure to North America from whence he did not return to France until 

 1838. He was made conservateur of the Museum of Havre, his native city, 

 and there he died December 12, 1846. 



It appears that LeSueur px'ojected a large work on the ichthyology of 

 North America. He even went so far as to issue a prospectus giving the 

 conditions of publication. This was issued in 1827 while he resided at New 

 Harmony. 



The wording is as follows: 



"Proposals 



fnr publishing by subscription 



a work on the 



Fishes of North America 



with plates draivn and colored from nature 



By 



C. A. Le Sueur. 



This will be published at New Harmony, Indiana, in numbers, with 

 four colored plates in each, and the necessary letter-press containing de- 

 scriptions of the species represented. Twelve numbers will constitute a 

 volume. 



Messrs. Tiebout and other artists from Philadelphia, who were there 

 occupied on the "American Entomology," are engaged for this work. 



Books with colored plates are generally beyond the reach of persons of 

 limited means; but it is intended that the present work shall be adapted to 

 the circumstances of all. The price to subscribers will therefore be forty 

 cents each number.
