Dr. W. II. Harvey’s Account of the Marine Botany of 
lorum diametro sesquilongioribus. Dredged in 6-7 fathoms in King George’s Sound (40). 
I have seen no fruit, but have little hesitation in referring this fine species to Wrangelia. 
It seems nearly allied to a plant from Cape Northumberland, distributed by me under the 
MS. name of Crouania insignis, but which is perhaps also a Wrangelia. 
141. Wrangelia velutina, II. Dasya velutina, Sond. ! Common at Eottnest and Garden Island, 
rare at King George’s Sound (108). I have found both the cystocarpic and tetrasporic 
fruits, which are exactly as in other species of Wrangelia. 
142. Wrangelia n. sp. ; fronde rigidiusoula e basi articulata ecorticata inferne 
stuposa pinnatim ramosa; ramis patentibus simplicibus v. iterum pinnatis ad genicula ver- 
ticillatim ramellosis; ramellis pluries trichotomis segmentis patentibus apice trifurcis 
acutissimis; fructu . . . Parasitical on the larger Fucoids, Eottnest (246). A very distinct 
species. 
143. “Weangelia Nitella, n. sp. ; fronde membranacea flaccida e basi articulata (articulis diametro 
4-6-plo-longioribus) ecorticata decomposite pinnata; ramis ramulisque sajpiiis oppositis 
distichis ad genicula verticillatim ramellosis; ramellis di-tri-chotomo-multifidis segmentis 
patentibus acutissimis; tetrasporis globosis ad ramellos sessilibus; cystocarpiis . . . Cast 
ashore at King George’s Sound and Eottnest, rare (213). Very similar in external habit 
to IK. multijida, but much more nearly allied to IK. squurrulosa and IK. myriophylloides. It 
is a much smaller and more flaccid plant than the latter, and closely adheres to paper in 
drying. Many of the branches, on my specimens, end in nearly naked cirrhose prolon- 
gations, indicating that they come from deep water. 
144. Wrangelia Halurus, n. sp. ; rosea, gelatinoso-membranacea (aqua dulci cito deliquescens) ; 
fronde e filo repente orta articulata ecorticata vage ramosa; ramis elongatis simplicibus 
basi et apice attenuatis ad genicula verticillatim ramellosis; ramellis dichotomo-multifidis 
patentibus obtusis; articulis ramorum diametro 2-3-plo, ramellorum multiplo-longioribus; 
cystocarpiis ramuios abbreviates coronantibus. On Caulinia stems at Fremantle and Kin^ 
«D 
George’s Sound (127). Very similar in aspect to Halurus equisetifolius, but much softer, 
of paler colour, and soon decomposing. The cystocarps are those of a Wrangelia. 
145. Wrangelia? abietina, n. sp. ; fronde cartilaginea crassa elongata (6-10 uncias longa) corti- 
cata decomposite pinnata; pinnis pinnulisque alternis distichis subhorizontalibus, ultimis 
subarticulatis tenuiter corticatis, ad genicula verticillatim ramellosis ; ramellis dichotomis 
incurvis obtusis; articulis diametro 3-4-plo-longioribus. Garden Island, rare (270). 
Possibly a species of Halurus. 
146. Weangelia? tenella, n. sp. ; pusilla (1^ uncialis), casspitosa; fronde tenuissima membranacea 
e basi articulata ecorticata vage ramosa; ramis subsimplicibus nunc iterum ramosis elon- 
gatis virgatis per totam longitudinem bipinnatis ; pinnis brevissimis (vix semilineam longis) 
oppositis V. verticillatis, pinnulis 2-3-cellularibus obtusis; articulis ramorum diametro 
4-plo, pinnarum 2-3-plo, pinnularum sesquilongioribus. On the Jetty reef, Eottnest, rare 
(285). I am doubtful whether to place this species in Wrangelia or CalUthamnion ; but 
place it provisionally in the former, on account of the tendency to verticillation in the 
pinnaj and ramelli.
