This species as originally described by S^ewberry has been found in only two localities 

 in North America, although it had been incorrectly compared by Newberry with Z. jug- 

 landium and Z. serratum of Heer, as obtained from the Tertiary of Europe. In 1883, New- 

 berry obtained it from the Green River group of Florissant, Colorado, and in 1906 Lambe 

 found it at Quilchena.
