number of vegetable gardens have of late years been established at the headwaters 

 along the creek furnishing the lake, and it is probable that Spdrgnnophihi^ Smifhi 

 has been introduced with watercress, etc., from some other locality within the last few, 

 say ten years, while the eye-bearing species may yet bQ living in the bottom soil.

Prof. Frank Smith has kindly sent me for comparison a full set of sections of 

 this species, also several mature specimens in alcohol and formalin. As, however, 

 Prof. Smith writes me that he intends to further work out the details of the anatomy 

 and histology of this species, I have not considered myself at liberty to more than
