Obs. Hall and Clarke (1893), in treating of the American species of Eumetria (E. 

 vera and var. costata, and E. verneuiliana), say they "are, perhaps, all repre- 

 sentatives of the same species." The writer regards them as one species, 

 varying in different localities in size and uumber of striations. Owen was 

 the first to observe this form and identified it provisionally with T. serpen- 

 tina de Koninck. Shumard, however, believed it to be distinct from that 

 species, and gave the name T. manyi four years prior to that of Hall.
