 GLOIOSIPHONIA CAPILLARIS.— C^m. 



Gen. Chab. — Frond gelatinous, filiform, tubular ; inner part of the tube composed of 

 longitudinal, anastomosing and interlacing filaments, the outer of minute cells 

 disposed in vertical moniliform series. Fructification : favellidia, immersed among 

 the vertical filaments, " to whose bases they are attached." Name from yXoihs,

 Hab. — On submarine rocks; in tide-pools near low water ; often cast on shore from 

 deep water. Annual. Summer. Not uncommon from Jersey to Orkney, as well as on 

 the Irish coasts. Particularly abundant at Peterhead on sandy rocks, as well as on slightly 

 muddy bottoms {Mr. T. Bell). Forfarshire and Moray Frith {A. C.) ; rather scarce in 

 clear shallow pools near low water, 



Geogr. Dist. — Atlantic shores of Europe. 



Description. — Root, a minute disc. Fronds much tufted, filiform, 

 from a slender base, gradiially thickening upwards to the middle, and 

 then tapering to a point ; about one-twelfth of an inch in diameter at 

 the thickest part, and from three to ten or twelve inches in length, 

 irregularly branched from near the base with branches similar to 

 the main stem, and these are again repeatedly subdivided in like 

 manner, all the branches being rather patent, shorter and more slender 

 upwards, giving the frond and all its divisions an ovate outline ; some- 

 times the main stem is branched from the base, but more frequently it 

 is naked for one or even two inches, and all the divisions are much 

 attenuated towards the base and taper to a long slender point. Struc- 

 ture consists of a thin tube formed of two strata : the inner composed 

 of longitudinal articulated, anastomosing and interlacing fibres, with 

 short oblong joints, traversed by a veiy narrow thread of endochrome, 

 the outer of vertical moniliform filaments, the whole set in a very lax 

 transparent jelly. Substance gelatinous, exceedingly soft and lubricous,
