the Colony of Western Australia. 
178. Hemineura crispata, n. sp. ; fronde pinnatifido-decomposita, lobis oblongis basi et apice angus- 
tatis obtusis oppositis margine subintegerrimis undulato-crispatis demum crispatissimis ; 
costa immersa superne evanescente, costulis obsoletis; coccidiis in costa loborum sessillbus 
ore producto rostratis; soris rotundato-hemisphsericis convexis secus marginem seriatis. 
Kottnest and King George’s Sound. Sent also by Dr. Curdle from Cape Northumberland 
(312). A smaller plant than H. frondosa. 
179. Nitophylldm cartilagineum, n. sp. ; fronde sessili avenia cartilagineo-membranacea rigida 
crassa dichotoraa ; laciniis linearibus pluries divisis crispato-undulatis obtusis patentibus; 
axillis rotundatis; soris minutis impressis per totam frondem sparsis. Garden Island, not 
uncommon (131). Eemarkably thick in substance, shrinking in drying, and imperfectly 
adhering to paper. Colour, brownish red. 
180. Nitophyllum n. sp. ; fronde pusilla (1—2 unciali) bifida v. pluries furcata basi 
cuneata stipitata; stipite breyi in costa mox evanescente prolongato; laciniis rotundatis ; 
margine processibus minutis ramosis dense fimbriato; soris per totam laminam sparsis. 
Parasitical on Ptilota coralloidea, at Garden Island, rare (268). I suspect my specimens are 
not fully grown, though one of them is in fruit. The elegantly fringed margin at once 
marks the species. 
181. Nitophylldm pulchellum, n. sp. ; pusillum (sub-biunciale), tenuissime membranaceum, roseuni, 
CEespitosum; fronde sessili avenia dichotoma fastigiata; laciniis lato-linearibus v. cuneatis 
undulato-crispatis patentibus obtusis; axillis rotundatis; soris rotundatis majusculis per 
totam frondem sparsis. King George’s Sound and Eottnest, on various Alga. Like a 
miniature N. punctatum, to which species it is perhaps too nearly allied (60). 
182. Nitophylldm minus, Sond. Garden Island and Eottnest (181). 
183. Nitophylldm ciliolatum, n. sp. ; fronde caspitosa sessili anguste-lineari dichotoma ramosissima 
ciliolis marginalibus et superficialibus passim echinulata. On Caulinia, &c., King George’s 
Sound (30). Very similar to N. minus, except in the presence of the ciliae, which I find 
constant in very numerous specimens examined. 
184. Nov. Gen.? My number (141) from Garden Island appears to belong to a new genus, allied 
to Nitopliyllum ; but without the cystocarpic fruit it is impossible to determine it. 
185. Phacelocaepus Lahillardieri, Endl. Common at Eottnest and Garden Island (134). 
186. Phacelocarpus alalus, n. sp. ; fronde costata; costa elevata bene definita utroque latere 
lamina angusta alata; ciliis subulatis distichis. Eottnest (261). Half the breadth of 
jP. Labillardieri, with a more strongly defined midrib and less deeply pinnatifid lamina. 
I suspect that several species are confounded under the name Labillardieri. 
187. Heeingia? JUiformis, n. sp. ; fronde c®spitosn, e surculis repentibus orta setacea filiformi v. 
apice compressa vage ramosa subdichotoma rigidiuscula. Garden Island, rare (182). 
Similar to H. mirabilis in structure, but the fruit is unknown. 
188. T)iCRAT>imiA Jiliforme, Sond. Garden Island (133). 
189. Diceanema Grevillii, Sond. King George’s Sound, Cape Eiche, Garden Island, and Eottnest 
(97). 
190. Dicranema revolutum, Ag. On Caulinia, in shallow water. Cape Eiche (128).
