Jordan, undertook the study of the species, and displayed 

 marked zeal and ability, publishing a number of papers before 

 his early death in his twenty-first year. These papers were 

 combined in a bulletin of the United States National Mu- 

 seum, entitled " The Myriapoda of North America, by Charles 

 Harvey Bollman, edited by Lucien M. Underwood" (1893). 

 They have had much influence on the present trend of method 

 and treatment of the group in question.

ENUMERATIONS with mere names of species of several classes 

 were early published; such were the "Check-lists of 

 the Shells of North America," by Isaac Lea, Philip P. 

 Carpenter, William Stimpson, William G. Binney, and Tem- 

 ple Prime. These lists were sometimes of families, as the 

 " Unionidae," by Lea, and the " Cyclades," by Prime; some- 

 times of a class, or a large part of a class, as the "Terrestrial 

 Gasteropoda" and the " Fluviatile Gasteropoda," both by 

 Binney ; and sometimes of faunal regions, as the " West 

 coast" (separated into the "Oregonian and Californian prov- 

 ince " and the " Mexican and Panamic province "), by Car- 

 penter, and the " East coast," by Stimpson. 



Various groups of shells were described and illustrated in 

 different ways under the general title, "Land and Fresh- 

 water Shells of North America," of which four parts were 

 issued between 1865 and 1875. 



"Part I," including the land shells, or "Pulmonata geo- 

 phila," was the result of a joint authorship by W. G. Binney 

 and T. Bland, and was not published till 1869. At a much 

 later period what may be considered as a new edition of the 

 work on land shells was published, and quite properly ap- 

 peared under a new title, as will be hereafter seen. " Part
