^Vhel> Waagen proposed Clionetes geinitzianus for thi.s species to replace the 

 older name first given it by Geinitz, he pointed out that Ghonetes glaber, used by 

 the latter, had long been preoccupied by Chonetes glaber Hall.'' While Chonetes 

 geinitziamis ha.s not yet come into use among American paleontologists, there can 

 be no question about the proprietj' of adopting the name. 



The representation of Chonetes geinitzianus in our collections is often scanty 

 and the preservation poor. About the only identifications which are believed to be 

 unquestionable are at two localities in the Leadville district (stations 2267 and 2268). 

 The form at Empire Gulch in the Leadville district (station 2264) is extremely' abun- 

 dant, but so poorly preserved as to make a certain identification impossible. A 

 single specimen of small size from near Glenwood Springs can probabh' be referred 

 here. 



In the San Juan region (at station 22'1:3, which is believed to be in the Kico 

 formation) Chonetes geinitzianus is found in moderate abundance. The specimens, 

 however, are rather undersized.
