Pinnae broadly rounded, two small indentations in the upper portion, 
giving it a trilobed appearance, rather than transverse, translucent yellow¬ 
ish, speckled with black dots on the upper margin; crossed from one side to 
the other by arched, broad bands of muscular fibre, which are reticulated 
by similar radiating bands. A deep broad sinus separates the pinnae from 
the parts surrounding the mouth. The orifice of the latter is trumpet¬ 
shaped, situated in a transverse cleft of the membranes which surround 
it and which are roundly produced on each side of it like the lower portion 
of a pea-blossom. Oesophagus slender, bright yellow. The neck by which 
the body hangs, is constricted, giving it a vase-like appearance. The 
intestines are variously tinted with brown, purple, and green. (Dali.)
