the Cape of Good Hope, of a still greater size and more robust and 

 shrubby habit, with numerous and compound branches, — evidencing- 

 the genial intluence of climate on the growth and appearance of these 

 corallines. 



2. S. Ellisii, climbiny^ Jlexuous ; the cells urceolate, bulged 

 at the hase^ with a ^-toothed rim : vesicles with the opening 4- 

 toothed. Ellis.

Hah. Parasitical on other corallines. 



Under the " Great-tooth Coralline" Ellis describes this shortly : 

 " The other species, which is the climbing one, is more branched, 

 the denticles are placed more asunder, and their mouths are wider : 

 The vesicles of both species are wrinkled." It has been always con- 

 sidered a variety of the preceding until separated from it by Milne- 

 Edwards on what appear to be sufficient characters of distinction. 

 I have seen no specimen.

Hab. " Loch of Belfast, Mr Templeton," Fleming. 



" Height about an inch ; slightly branched ; cells narrow, tubular, 



produced ; the vesicles oval, lengthened, narrow at the base, covered 



towards the summit with lanceolate spines. This species is of a 



more delicate texture than the preceding, (Thoa muricata), the ve- 

 sicles are of a different shape, and the stem is simple. It was given 

 to me by an accomplished naturalist, the late Mr Templeton of Orange 

 Grove, Belfast. It adheres apparently to a gramineous leaf, proba- 

 bly of a zostera, and therefore may be considered an inhabitant of shal- 

 low water." Fleming. 



4. S. KUGOSA, cells ovate, twinkled transversely, the mouth nar- 

 row with 3 or 4 small teeth on the rim. J. Ellis.
