546 ZOOPHYTES. 



Feejee Islands. Exp. Exp. 



The clumps are tortuously branched, the branches sometimes 

 widening and giving out a cluster of finger-like branchlets nearly in 

 the same plane, and in other parts subdividing irregularly. Below, 

 the branches are a fourth of an inch thick ; but above they are gene- 

 rally a little more than an eighth, and at apex scarcely a line. If 

 applied to the tongue or lips when first taken from the water, it pro- 

 duces a stinging sensation. This species is much more slender than 

 the akicornis, and has very minute cells. 



The Sea Ginger, of Hughes, (Hist, of Barbadoes, p. 289,) appears to be another spe- 

 cies, and is probably identical with the akicornis. It is from the West Indies. 



The Millepora akicornis, figured by Esper, in his Pflanz. Fortsetz. i., tab. 26, has 

 nearly the size and habit of a variety of the above species, but is described as having 

 quite large cells, for a species of the genus. The specimen was from the island of St. 

 Thomas ; it consists of several slender flattened stems about two inches high, which are 

 subdigitate or furcate above, and rise, nearly in the same plane, from a sublamellar base.

5. MILLEPORA PLICATA. (Esper.} 



M. grandis, bene lamellatis, erectis, tenuibus, superne per multas pottices 

 fa" crassis, apice acutis; indso-lobatis, inter dum coalitis; lateribus 

 obsolete rugosis verticaliterque carinatis. 



Large, neatly lamellate, erect, thin, above for several inches from the 

 margin fa of an inch thick, and at apex acute ; inciso-lobate, some- 

 times coalescent; lateral surface minutely rugose, and vertically 

 carinate. 



The specimen affording this description is a clump of erect folia, 

 some of which are fifteen inches high and six or eight wide, and re- 

 markable for being quite thin, and for two inches from the margin 

 more or less translucent. The surface is finely plicate or vertically 

 carinate, especially near the summits.
