CLADOPHORA GATTYA, n. sp. 
CraporHora Gattye; filaments an inch long, dingy-green, capillary, 
matted together in dense tufts, not much branched, dichotomously 
divided, flexuous, with few ramuli; articulations in all parts of the 
frond nearly uniform, about once and half as long as broad, filled 
with endochrome ; the dissepiments very narrow, contracted. 
Has. On rocks (?) near low-water mark. Locality uncertain, Mrs. Gatty. 
Descr. Filaments about an inch long, as thick as human hair, or somewhat 
thicker, matted together in dense ropy tufts, irregularly branched, somewhat 
dichotomous, the angles rounded ; ramuli few and patent. Articulations 
very uniform, about once and half as long as broad; filled with oliva- 
ceous (?) or dull green endochrome, and separated by exceedingly narrow 
dissepiments. Apices on my specimen often broken. Substance mem- 
branaceous, adhering to paper.

A puzzle, figured with the hope that it may lead to more: 
certain information. The external habit is between that of 
C. uncialis and Ectocarpus littoralis, but the threads are very 
much more robust than in the former; and differently branched 
from the latter, as well as more robust. ‘The plant is, however, 
much battered and water-worn, having most of its upper 
branches and ramuli broken off:—and I am not prepared to 
say whether it be not some species im a dilapidated condition, 
whose proper character is thus concealed, or as it were shown 
in caricature.
