A single complete specimen most nearly resembling- Liagora 

 TUdcnii in its branching and structure. It is much more slender 

 than tlie type of this species and has the smooth texture of a Ne- 

 malion on account of the projection of the cortical branchlets above 

 the calcareous stratum. The central cylinder consists primarily of 

 filaments of large trumpet-shaped cells, each of which increases in 

 diameter from 10-15 mic. at the base to 30-45 mic. at the upper end, 

 where it bears the next cell of the medullary filament and also a 

 cortical branchlet. These branchlets are shorter and much stouter 

 below than in L. corymbosa, and seve;ral of the basal cells bear 

 lateral branching filaments. The basal cells are short, irregularly 

 cylindrical, about 10x30 mic, the median ones somewhat longer 

 (18-10x40-50 mic), the terminal ones broad ovate (6-8x9-10 mic.) 

 The transition in form and size is gradual. The lowest cells bear 

 Some of these develop directly into additional branchlets, some 

 form auxiliary medullary filaments. 



This is possibly a distinct species, but in the absence of more 

 material, I prefer to regard it as a variety of L. Tildenii.

Frond terete, about 10 cm. long, 2 mm. in diameter at the 

 base, tapering gradually upwards, dichotomously decompound, with 

 a soniewhat granular incrustation through which project the free 

 peripheral filaments ; central cylinder of large, closely packed cells 

 surrounded by a layer of intertwined, small, cylindrical cells.

The medullary cells bear the cortical branchlets which consist 

 of filaments of almost cylindrical cells, the outer ones about 13x26 

 mic. The distal cells of the filament often bear globose antheridia 

 consisting of short branching filaments with cells about 1.5 mic. in 

 diameter. Other filaments bear long, filiform appendages about 

 2.5 mic. in diameter and 600 mic. long, somewhat clavate at the 

 tip.
