" This species exists in two very dissimilar forms, 

 which have been considered distinct species 

 (the typical A. pellucidum, and A. constella- 

 iutn Verrill), but which are in reality not even 

 true subspecies, as is shown by some colonies 

 which in one part have the typical pellucidum 

 characters, while in the remainder of the 

 colony the constcllatum characters are equally 

 well developed." Van Name.
