cide if there are the three species very much alike, one in each 

 genus, unless one had samples of the three so described. In any 

 case there appears to be but the one on the West coast, conse- 

 quently, the matter does not need to be settled here. Confusion 

 arises in a very different way as well. ]\Iany authors have made 

 no distinction between Calycella syringa and Calycella pygmma 

 but have called every Calycella that would answer to either type, 

 Calycella syringa. It seems to me that there are two distinct 

 types, as shown by Hineks' figures,^^ though as in the case of 

 many other closely allied species there may be intergradations. 

 Of the west coast investigators, Clark and Calkins only have 

 shown drawings to scale. These drawings indicate the smaller 

 form, and it may be that the other cases reported are similar, 

 though there is no means of knowing. It is quite possible, there- 

 fore, that Calycella pygmcea and not Calycella syringa, is the 

 common species on the Pacific Coast.
