and D. sparsa; but its tentacles are stout and have 16 lamine, 
while those of D. pusilla are longer and more slender with 9 
lamine, and those of D. sparsa have 8 or 9 lamine. The plumes 
of D. inconspicua, although not easily seen, also present some 
points of difference from those of the other two species named,
