PI. 74, 



1-3. 



DiagTWsis. — Nearly intermediate in general appearance between H. levivscula 

 and B. leviuscula vntltispina, but the abiictinal plates smaller with fewer spinelets 

 than in muUispina and papular areas usually relatively larger; adanibulacral plates 

 with about fifteen spinelets (hence fewer than in viriltisjnna) and with two spinelets 

 in the furrow onlv at tip of ray, or not at all; spinelets of abactinal plates delicate, 

 similar to those of vntltispina. 



Description.— This variable form seems to be a southern variety of muUispina, 

 intermediate with leviuscula. A number of specimens have been classified as inter- 

 grades between di/scrita and leviuscula. Apparently also the transition to tj-pical 



a SfjoKprnc = hard to determine, referring to the staliw of the form.
