 thickness. The species is much larger and coarser than the humilis 

 or tortuosa. 



Sea Ginger, or Palmed Harfs Horn, 



Hughes's Barbadoes, 289, with a plate, 



may be this species ; it is from the shores 



of Antigua.

The Millepora clavaria of Ehrenberg, is, as he states, near Esper's tab. 9, but dif- 

 fers in not having the cells in clusters. It is described as follows: " Pedalis, lobato-divisa, 

 ramosa, ramis brevibus, tuberculosis, clavatis, apice rotundatis, nee cristatis, poris (cellis) 

 crebris, parum regularibus." Locality unknown. Op. cit., G. lxxiv.,sp. 5. 



M. moniliformis. Under this name we notice a Millepora from the West Indies, 

 which occurs incrusting axes of Gorgonije, forming a series of disjointed bead-like 

 pieces, some of which are rounded, one to two lines thick, and others have a long pro- 

 cess, on one or two sides, while others are broad and lobed. It is figured by Esper, on 

 tab. Gorgon., 15, Pflanz. ii. 



which the cells are not so distinctly clus- 

 tered as represented by Esper ; it may be 

 a distinct species as made by Ehrenberg ; 

 see below, M. clavaria. Esper, tab. 5, 

 variety digitata, represents a reticulate 

 frond of coalescing branches, five inches 

 broad, from the West Indies ; it is near 

 the tortuosa in the size of its branchluts 

 and appearance.

Lax ramose, branches every way divaricate and long flexuous, 

 nearly terete, \ to an inch thick, remotely coalescent, attenuated 

 above, and subacute at apex. Corallum having the cells quite 

 minute and scattered. 



This species is described from a dendroid specimen in the coral col- 

 lections of Peale's Museum, Philadelphia. It is remarkable for its
