the Colony of Western Australia. 549 



178. Hemineura crispata, n. sp. ; fronde pinnatifido-deoomposita, lobis oblongis basi et apice angus- 



tatis obtusis oppositis margine subintegerrimis undulato-crispatis demum crispatissimis; 

 costa immersa superne evanescente, costuUs obsoletis; coccidiis in costa loborum sessilibus 

 ore producto rostratis; soris rotundato-liemisphcericis convexis secus marginem seiiatis. 

 Rottnest and King George's Sound. Sent also by Dr. Curdle from Cape Northumberland 

 (312). A smaller plant than H. frondosa. 



179. NiTOPHTLLUM cartilacjineum, n. sp. ; fronde sessili avenia cartilagineo-membranacea rigida 



crassa dichotoma ; laciniis linearibus pluries divisis crispato-undulatis obtusis patentibus ; 

 axillis rotundatis; soris minutis impressis per totam frondem sparsis. Garden Island, not 

 uncommon (131). Remarkably thick in substance, shrinking in drying, and imperfectly 

 adhering to paper. Colour, brownish red. 



180. NiTOPHYLLUM _/?7nJna<«m, n. sp. ; fronde pusilla (1-2 unciali) bifida v. pluries furcata basi 



cuneata stipitata; stipite brevi in costa mox evanescente prolongato; laciniis rotundatis ; 

 margine processibus minutis raraosis dense fimbriate; soris per totam laminam sparsis. 

 Parasitical on Plilota 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. NiTOPHTLLCM/)u/c/ieH«i«, n. sp.; pusillum (sub-biunoiale), tenuissime membranaceum, roseum, 



CECspitosum; 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 Rottnest, on various Alff(e. Like a 

 miniature N. punctatum, to which species it is perhaps too nearly allied (60). 



182. NiTOPHYLLUM minus, Sond. Garden Island and Rottnest (181). 



183. NlTOPHVLLL'M ciUolatum, n. sp. ; fronde caespitosa sessili anguste-lineari dichotoma ramosissima 



cilicilis marginalibus et superficinlibus passim echinulata. On Caulinia, &c., King George's 

 Sound (30). Very similar to N. minus, except in the presence of the cilias, 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 KitoplujUum ; but without the cystocarpic fruit it is impossible to determine it. 



185. PH.\CELOCi\i:pus Lahillardieri, Endl. Common at Rottnest and Garden Island (134). 



186. Phacelocabpus alatus, n. sp. ; fronde costata; costa elevata bene definita utroque latere 



lamina angusta alata; ciliis subulatis distichis. Rottnest (261). Half the breadth of 

 P. Lalillardieri, with a more strongly defined midrib and less deeply pinnatifid lamina. 

 I suspect that several species are confounded under the name Lahillardieri. 



187. Heringia? JUiformis, n. sp.; fronde csespitos ■, u surculis repentibus orta setacea filiformi v. 



apice compressa vage ramosa subdichotoma rigidiuscula. Garden Island, rare (182). 

 Similar to H. mirahilis in structure, but the fruit is unknown. 



188. DiCKASt.TiA. jiliforme, Soud. Garden Island (133). 



189. Dickanema Grevillii, Sond. King George's Sound, Cape Riche, Garden Island, and Rottnest 



(97). 



190. Dicranema reyotewwi, Ag. On Ca(A'n!a, in shallow water. Cape Riche (128).
