Dr. W. II. Harvey’s Account of the Marine Botany of 
;516. Caulerpa n. sp. ; surculo setaceo glabro ; frondibus filiformibus simplicibus v. parce 
ramosis, ramis vagls, foliis spiraliter laxe insertis subtristichis erecto-patentibus subulatis 
brevibus mucronatis Iseteviridibus. On the Natural Jetty at Eottnest, very rare (215). A 
slender species, 1-2 inches high. 
317. Cauleepa hypnoides, E. Br. Abundant in tide-pools and borders of reefs, at Eottnest and 
Garden Island (185). 
318. Caulerpa Mulleri, Sond. ! surculo crasso squamulis cylindraceis dichotomis dense muricato; 
fronde ereota stipitata oblonga obtusa pinnata; stipite pinnisque foliolis undique densissime 
obtectis, foliolis geminis basi unitis cylindraceis obtusis apice bi-mucronulatis erectis im- 
bricatis intense viridibus. On border reefs and sides of deep tide-pools at Eottnest (205). 
Nearly related to C. hypnoides^ but a much stronger and coarser plant, readily known at a 
glance, when the two are seen together, though difficult to characterize. In C. hypnoides 
the surculus and base of stem are clothed with far more densely set and muricated squaina3, 
and the folioli are much smaller, softer, more patent, more laxly set, and more acute. 
319. Cauleepa ohscura, Sond.! Abundant at King George’s Sound; and in tide-pools, &c., Eott- 
nest (77). The fronds are often 12-18 inches long. 
320. Cauleepa /wm/o/fa. Hook, and Harv. A few fragments cast ashore at King George’s Sound, 
February ( ). 
321. Cauleepa n. sp. ; surculo glabro ; frondibus erectis simplicibus (brevibus) articu- 
lato-constrictis glabris, foliis parvis oppositis ovoideis distichis v. tortione caulis quoquo- 
versum directis. On very shady rocks, usually on the under surface of table-reefs, Eottnest. 
The distichous form is readily distinguishable; but that with leaves turned to all sides 
resembles G. sedoidesiw miniature; but is readily known by its articulate stem and opposite 
leaves (214). I suspect that it is S. sedoides, of Bonder in PL Preiss. 
322. Caulerpa corynepliora, Mont. King Geoi'ge’s Sound, and in deep tide-pools, Eottnest (101). 
323. Cauleepa scalpelliformis, E. Br. King George’s Sound, and on border reefs, Eottnest (206). 
324. Steuvea jdurnosa, Sond. Abundant on all the shallow reefs at Eottnest, but scarcely in 
season in June, when I visited the island (216). 
325. Struvea macrophylla, n. sp. ; fronde oblongo-ovali maxima (4-5 uncias longa, 3 uncias lata) 
crenata, tubulis anastomosantibus pluries pinnatis. Champion Bay, Mrs. Drummond, Jun. 
A single specimen, bleached white, tvas sent by Mrs. Drummond to Mr. Sanford, who kindly 
presented it to me. The frond closely resembles a beautiful structure of “ old point-lace,” 
and as it is very tough and strong, it might be manufactured into ladies’ natural-lace collars, 
by merely tacking on a border of net. 
326. PoLTPHYSA Ptnicidus, Ag. Fucus Peniculus, E. Br. Extremely abundant, at all seasons, in 
Princess Eoyal Harbour, King George’s Sound, growing on old shells. Not seen else- 
where (1). 
327. Penicillus Arhuscula, Mont.? Abundant, on shallow, sand-covered reefs at Eottnest (204). 
It varies much in size. The stem is sometimes scarcely twice as thick as a hog’s bristle; 
sometimes as thick as a goose-quill. I have not compared with Montague’s plant. 
328. Halimeda macroloba, Dne. Cape Eiche and Eottnest, on the reefs (226). 
329. CoDiUM tomentosum, Ag. Abundant everywhere (45).
