22. Chylocladia kaliformis, Grey. (Fucus kaliformis, Turn. t. 29.) 
George Town, V. D. L., JR. Gunn, Esq., n. 1323. 
23. Chylocladia Tasmanica, Harv., M.S.S. 
George Town, V. D. L., R. Gunn, Esq., n. 1295.—Two imper¬ 
fect and half-decomposed specimens of a fine Chylocladia, pro¬ 
bably new, but too closely allied to C. articulata for me to venture 
to describe it without more perfect specimens. The substance is 
far more gelatinous than in C. articulata, and the size, unless we 
compare it with the gigantic state figured by Turner, is much 
greater. The length of the lowermost constrictions is, in one 
specimen, an inch and in the other 1J inches. It appears to 
decompose rapidly in fresh water, throwing off its ultimate ramuli 
as a Starfish does its rays. The frond is irregularly dichotomous, 
with very patent axils, constricted at the branching; the upper 
divisions umbellate, 4-5 new branches springing from the top of 
an old one, and these from their apices giving birth to saccate 
clavate ramuli. 
Tribe 3. Spiijerococcoide.t., J. Ag. 
24. Hypnea musciformis, v. Valentia, Harv. in Hook. Journ. 
Bot. 1 , p. 153.—Fucus Valenti®, Turn. t. 78. 
George Town, V. D. L., R. Gunn, Esq., n. 1314.—This spe¬ 
cimen bears sphmrospores in the patent ramuli. 
25. Gracilaria lichenoides? (Fucus lichenoides, Turn. t. 118?) 
George Town, V. D. L., R. Gunn, Esq., n. 1292.—Either 
G. lichenoides or a species very closely resembling it. The spe¬ 
cimen produces irregular wartlike nemathecia. 
26. Sphrerococcus australis, Harv.; caule brevi, carnoso, cylin- 
drico, mox cuneato et in fronde lineari, compresso-plana, 
membranacea, coccinea, ecostata abeunte; fronde decompo- 
sito-dichotoma; segmentis circumscriptione flabelliformibus, 
ramulis dichotomy multifidis sensim angustioribus distichis 
patentibus pinnatis; axillis rotundatis obtusissimis; apicibus 
acutis, laceratis; coccidiis acutis demum tuberculatis ad apices 
ramulorum sessilibus.
