—R. I. 792. Atl. Fl. Par, 41 E.—Very small and slender. 
Branchlets very much divided, forming little globose compact 
masses which are often much incrusted. Nucules subglobose, 
with 6—8 strize, minute but 3 times the diameter of the branchlets 
and placed outside of them. Globules much larger than the 
nucules.—Peaty ditches. Cambridgeshire. A. VIL. VIIL  E. 
uu. Polypella. Globules lateral on the jomings of the chief ray 
of the branchlets between the lateral rays (bracts) which are 
always shorter than the chief ray.—Rays of many decreasing 
joints. 
7. C. Smithii (Bab.) ; dioecious, st. slender equal flexible trans- 
parent, branchlets blunt those forming the primary whorls simple 
sterile long jointed (?), others on axillary branches many densely 
crowded having 3 short and 1 long bract at their first joing, 
globules stalked subtended by the 3 shorter bracts, nucules un- 
known.— C. nidifica Sm. (not Miill.), E. B. 1703 (principal figure). 
—Small. Branchlets in bird’s-nest-like masses, springing from 
the axils of the simple branchlets of the primary whorl.—Lancing, 
Sussex. Mr. Borrer. A. IX.? 
8. C. prolifera (A. Br.) ; monecious, st. slender equal flexible 
transparent, branchlets blunt those forming the primary whorls 
simple sterile long usually of 3 or 4 joints, others on axillary 
branches many densely crowded bearing 3 short and 1 long bract 
at their first joming, globules sessile in company with one or 
more nucules and subtended by the 3 shorter bracts.—Small. 
Like the preceding. Nucules small, faintly striate. Granules 
sessile (?). The presence of true bracts distinguishes this species, 
C. Borreri, and C. Smithit from C. polysperma and C. flexilis. 
—Ditches. Cley, Norfolk. Copford, Essex. A. IV. E. 
9. C. Borreri (Bab.); moncecious, st. slender equal flexible 
transparent, branchlets strongly mucronate those of the primary 
whorls simple sterile long jomted, others on axillary branches 
many densely crowded bearmg 3 short and 1 long bract at their 
first and sometimes second joming, globules stalked or sessile in 
company with several nucules and subtended by the 3 shorter 
bracts.— C. nidifica Borr., E. B. S. fol. 2762, note.—Like but 
larger than Nos.7and8. Branchlets suddenly contracted below 
the acute apiculus. Larger “bract”’ occasionally bearing a 
cluster of bracts.—Marsh ditch, Henfield, Sussex. Mr. ane 
A. VII. : 
10. C. polysperma (A. Br.); moncecious, st. slender equal 
flexible transparent, barren and fertile branchlets of the primary 
whorls once or twice unequally branched, middle branch longest, 
branchlets of axillary branches many densely crowded much sub-
