Sample 16. 



This Alga forms an extensive soft jelly, several millimetres in width, 

 and, in the preserved condition, almost colourless, or at the best but a 

 very pale green. The numerous cells are irregularly embedded at 

 variable distances in the mucilage and are spherical before, but usually 

 oval, after division (Fig. 6 a). I have been unable to detect apyrenoid 

 in the cells. The delicate membrane of the cells is burst, after the 

 manner characteristic for the genus, into one or more pieces, and the 

 fragments are found in smaller or larger numbers in the surrounding 

 mucilage (Fig. 6). 



Fig. ti. — Schizochlamys hyalina, n. sp. A. Small portion of the jelly 

 showing the irregular distribution of the cells and the fragments of 

 cell-membrane which are cast off. H. A small portion of the same 

 enlarged. A x 375, B x 750. 



This species differs from the two hitherto known (S. gelatinosa, A. 

 Br., and S. delicatulq, West) in the almost colourless plant-mass, in 

 the oval shape of the cells after division, and in the fact that the 

 membrane is ruptured into a varying number of fragments.
