geminate; lower rather longer than broad; upper shorter, •§■ in. broad, con- 
stricted at the nodes. — C. clavata, var. Darwinii, El. Antarct. 493. t. 192.

2. C. aerea, Billivyn , Conf. t. 80; — FI. JV. Z. ii. 263. Filaments nu- 
merous, erect, pale green below, paler above, gradually dilated upwards ; 
lowest articulation longest, 5 times as long as broad, the middle ones half as

Port William, Lyall. (Tasmania.) 
108. TYNDAEIDEA, Bory. 
Filaments simple, green-yellow or brown, finally inosculating by transverse 
tubes. Endochrome of subglobular masses, which, after conjugation, unite 
and form a roundish globule lodged in one of the articulations, or in the 
connecting tube. 
In streams, pools, ditches, aud wet places, often forming spreading masses of coloured 
scum. 
1. T. anomala, Ralfs ; — FI. N. Z. ii. 263. Joints equal or shorter 
than long, constricted here and there. Cell-wall often very thick. — E. Bot.

Kuetz. Sp. Alg. 447. 
Freshwater, Colenso. (Europe.) — Apparently the same as the British plant, but impos- 
sible to determine from comparison of dried specimens. 
2. T. ? byssoidea, Harv. in FI. N. Z. ii. 264. Filaments blackish, 
gelatinous, arachnoid, greenish under the microscope ; articulations about 3 
times as long as broad. 
Freshwater lake, Kapiti, Cook’s Straits, Lyall. 
109. CALOTHRIX, Agardh. 
Frond of capillary, green internally, short, tufted or fascicled, rather rigid 
filaments, fixed, without a mucous coat, and without a waving motion in

lenticular sporules. 
Fresh- and salt-water small Algae.
