Nemasloma .] 
1. RT. intestinalis, Harv. in FI. N. Z. ii. 255. Frond, delicate, red- 
purple, 6-8 in. long, j-i broad, cylindric or compressed, tubular, linear, 
vaguely branched or irregularly divided into simple or forked branches, which 
are constricted at the base and attenuated, or 2-horned at the tip ; medullary 
stratum very fluid. Spore-masses scattered over the whole frond, suspended 
below the periphery, enclosed in a dense plexus of filaments. 
Preservation Harbour, on rocks, Lyall. 
2. RT. ? attenuata, Harv. in FI. N. Z. ii. 255. Nearly related to N. in- 
testhialis, but the only fragment known is larger, 15 in. long, -§- in. wide below, 
tapering upwards, compressed; medullary stratum lax. 
Jackson’s Bay, Lyall. 
3. RT. pinnata, Hook.f. and Harv. FI. N. Z. ii. 255. t. 120 B. Frond 
soft, pale red, 4-5 in. long, and as broad in outliue, undivided or forked, 
in. broad, closely regularly set, with long, distichous, horizontal, oppo- 
site or alternate pinnae, which are ■$— } in. broad, attenuated to both ends ; 
pinnae again pinnate, with similar but much smaller ciliiform pinnules ; me- 
dullary stratum compact. 
Akaroa, Lyall. (A single specimen.) 
4. RF. Daviesii, Harv. in FI. N. Z. ii. 255. Frond purple-red, between 
gelatinous and membranous, 6-8 in. long, stipitate, foliaceous, ovate-lanceo- 
late, — in. broad, pinnate, with ovate-lanceolate lobes, 2-4 in. long and 
^—1 in. wide ; pinnae tapering to both ends, crisped and curled, spreading, 
toothed and ciliate. Spore-masses abundant, scattered over the whole frond. 
Tawanga, Davies ; Otago, Lindsay. 
5. KT. endiviaefolia, Harv. in FI. N. Z. ii. 255. Frond cuneate at the 
base, excessively variable, vaguely dichotomously palmate or lacini ate, narrow- 
linear and multifid, with acute forked tips, or broad and subpinnately 
branched, with dichotomous, acute or truncate, entire or toothed segments ; 
axils rounded. 
Port Nicholson and Blind Bay, Lyall. — Harvey thinks this so variable that it may be a 
form of Daviesii. 
6. RT. prolifera, Harv. in FI. N. Z. ii. 255. Upper half of a frond, 
8 in. long, cuneate, 1 in. broad, widening upwards to 2 in. then forking, ge- 
latinous, everywhere beset on the surface and margins with filiform or cuneate- 
multifid leaflets, less than 1 in. long. 
Akaroa, on stones, Lyall. 
88. CATERELLA, Greville. 
Frond dull purple, cylindric, constricted at intervals, subtubular, branched ; 
structure of 2 strata, medullary of interlacing anastomosing filaments, pass- 
ing into a cortical of vertically-placed moniliform minute filaments cohering 
at the periphery. Conceptacles formed in minute ovoid or subglobose 
branchlets. Tetraspores transversely divided, scattered through the periphery.
