Bulimoides is characteristic of the Californian and Columbian re- 

 gions, judging by the authentic records. But few of the published 

 references can be relied upon, as it has been universally mixed with 

 G. bulimoides techella and G. b. cockerelli. It will probably be found 

 to extend well into the Columbian region. Records east of the Rocky 

 Mountains all seem referable to techella or cockerelli.
