Bujfhctmia speciosa, nov. sp. A small plant from a quarter to one 
and a quarter inch in length and about 1 mm. in breadth. Characters 
the same as those of the genus. 
Tellamia. — A new genus of Chlorophyceae named in honour 
of Mr. R. V. Tellam, of Bodmin. Thallus yellow- or brownish-green, 
or more rarely a clear grass-green, minute; composed of radiating 
branched jointed threads with tun-shaped or oval cells very much 
constricted at the joints. At first the filaments are rolled up into an 
almost spherical ball, afterwards they spread out and branch in all 
directions. Reproduction by zoospores formed in the swollen cells, 
which frequently become nearly globular. The species of this genus 
grow in the periostracum of the common yellow periwinkle ( Liitorina 
obtusata , L.). 
Tellamia contorta , nov. sp. Filaments closely interwoven, much 
branched in an irregular manner, branches curled and twisted, fre- 
quently falcate, cells oval, 3-10 /x in diameter, usually 6-9 n long but 
sometimes much longer. Irregular swellings are not uncommon in 
this species. 
Tellamia intricata, nov. sp. Fronds slender, much branched, 
branches opposite or alternate, patent, seldom falcate or recurved. 
Cells oval or oblong, 2-5-4 /x in diameter, 4-24 fx long. The two 
species frequently grow side by side, but are easily distinguishable, 
the filaments of T. contorta being much darker coloured than those of 
T. intricata. 
Myriotrichia densa, nov. sp. In the Journal of Botany for November, 
1891, Mr. T. H. Buffham describes and figures the plurilocular 
sporangia of a Myriotrichia which he refers to M. clavaeformis , Harv., 
at the same time expressing surprise that the form of this species 
bearing plurilocular sporangia should be so different from that bearing 
the unilocular. Since the publication of that paper I have found the 
plant figured by Mr. Buffham, at Arran, Cumbrae, and Weymouth, 
but with both unilocular and plurilocular sporangia. Both forms are 
exactly alike outwardly. Frequently both forms of reproductive organs 
occur on the same individual. The plant appears to me quite distinct 
from any described species of Myriotrichia ; I have therefore named 
it M ’. densa .
