but rather poorly preserved specimen of the same species 
which was collected by a late Director of the Survey, 
Dr. A. R. C. Selwyn, in 1880. This is the only entire 
specimen of an American Harpes of which the writer has

(see Plate III, fig. 6). In front of the glabella, the brim 
of E. dentoni is narrow, deeply concave, and the anterior 
rim is curved upward, while in E. ottawaensis the brim at the
