and radiately lined; just above the base there are two circles 
of conspicuous pores. ‘The tentacles are numerous, crowded 
together toward the margin, in length more than half the dia- 
meter of the disk (about ‘5 of an inch in the figured specimen), 
moderately slender and scarcely acute. The lobes of the 
mouth are bright yellow; a broad circle of purple surrounds 
the mouth; the rest of the disk is light blue with darker radii; 
the tentacles are bright orange-red ; the body is light purplish- 
red, with dark red blotches and longitudinal streaks, especial 
near the base. Other varieties of coloration occur. 
It lives like the other species of the genus, adhering to dead 
shells inhabited by hermit-crabs. A variety of this, or an allied 
species, is abundant on the eel-grass and alge.
