This species appears to suggest a transitional type between L. flagellate^ or some <»f its form and 
L. Ilelluodis which it approaches in the character of its appendages. The br. iches of the latter an 
remarkably developed, and although in the material from Helluodes they are mostly broken, the spiral 
twist of the extremities seems characteristic of this as well as of the type material, supp ised to have (m Birred 
on Hexagonia, although the determination in the last instance was uncertain.

flated, somewhat abruptly contracted distally to form the unusually large broad tip, die distal half

suffused portion obscurely punctate. Outer appendage consisting of a be .1 cell deeply blackened ester 
nally (the blackened area continuous with the black insertion-cell and involving also the external walls 
of the two cells immediately above it) producing from one to three brandies arranged antero-] teriorly, 
which may be once or twice branched in a similar fashion, the branehlets long, slender, drooping, hyaline, 
some of the lower cells suffused with reddish brown: the inner appendage consisting of a basal evil about
