 speciosum 



Only two species, cereum and lentiim^ seem to be common 

 to both the coast region and the Sierra Nevada, and so far as I 

 know are found in the coast region only in the high mountains 

 of the eastern part of Ventura county, where the two mountain 

 systems are more or less connected. R. cereum should be ex- 

 pected to occur in the high mountains of the north coast region, 

 especially in the innermost ranges. 



Since the original description of a species should be the 

 most important one, I am using it under every species in this 

 paper, supplementing it by such observations as seem helpful 

 in the light of later and more extended knowledge.
