MARINE ALG^ FROM THE KERMADECS 21 



Mr. J. Bracebridge Wilson collected this species on Jan. 23, 

 1886, at Port Phillip Heads, as the specimen in the British Museum 

 shows. In his catalogue of algae collected at or near Port Phillip 

 Heads and Western Port, he gave it J. G. Agardh's MS. name, 

 Spatoglossum ciineatum. Agardh described the plant in his Ana- 

 lecta Algologica Gont. i. p. 30 (1903), under the other name. Mr. 

 J. B. Wilson's rich herbarium of Victorian algas is in the British 

 Museum ; and it may be added that an interesting biographical 

 notice of him and a portrait were published by Dr. J. H. Maiden 

 iu the Victorian Naturalist, xxv. pp. 116, 117 (1908). 



Geogr. Distr. Victoria. 



Gymnosonts nigrescens J. Ag., nos. 1362, 1365, 1374. Cast up 

 on Denham Bay Beach. 



Geogr. Distr. North, South, and West Australia. 



Dictyota p-olificans A. & E. S. Gepp, nos. 1314, 1323. Meyer 

 Island. 



Geogr. Distr. New South Wales and Queensland. 



Sargassum fissifolium J. Ag., no. 1367, on rocks near low-water 

 mark, Meyer Island ; no. 1368, on rocks between tides, Fleetwood 

 Bluff, Sunday Island; no. 1369, cast up on Denham Bay Beach, 

 Sunday Island. Mr. Oliver says : " This is the most abundant 

 seaweed found growing on the rocks of Sunday and Meyer Islands. 

 It does not grow above the level of low-water mark, except on 

 rocks in exposed places, where they are continually washed by the 

 waves, and in rock-pools near the south side of a cliff". Its distri- 

 bution is thus determined directly by the amount of heat received 

 from the sun." 



Geogr. Distr. Queensland. 



Chantransia sp., no. 1361. Without fruit. Epiphytic on 

 Gynmosorus nigrescens, Denham Bay Beach. 



Galaxaura sp., no. 1351a. Kocks near low-water mark, Meyer 

 Island. The same species was collected during the visit of H.M.S. 

 'Herald' in 1854, and is placed under G. lapidescens in Kew 

 Herbarium. To what modern species these plants should be 

 referred we do not attempt to decide until we can make an 

 adequate study of the entire genus. The large number of new 

 species created by Kjellman in his monograph of Galaxaura have 

 vastly increased the difficulty of identifying specimens. 



Zanardinia marginata J. Ag. ( = Brachycladia marginata 

 Schm.), no. 1355. Sunday Island. 



Geogr. Distr. North and South Atlantic. North and South 

 Pacific. Indian Ocean. 



Gelidium longij^es J. Ag. " Densely tufted. On rocks between 

 tidal marks, Nov. 1908." This specimen agrees in habit and 

 structure with a specimen from New Zealand in the British 

 Museum Herbarium collected by Berggren, and named by J. G. 

 Agardh Gelidium longipes. The Kermadec plants differ only in 

 being shorter and in not being so freely branclied, nor somewhat 

 compressed at the apices, as in Berggren 's plant. However, the
