5. C. L.EVIS, “ dichotomously branched , cylindrical , the pores 
wide , wztfA simple mouths” Rev. Dr Fleming. 
Cellepora laevis, Flem. Brit. Anim. 532. L’Escharelisse, Blainv . Acti- 
nol. 428. 
“ A single specimen from deep water, Zetland,” Fleming. 
“ Height an inch and a quarter, diameter one-tentli ; the branches 
are smooth, with the orifices of the cells smooth and concave ; to- 
wards the extremities the branches are rough with the forming cells, 
and the orifices are more declining, circumscribed, a little prominent, 
with a blunt process at the proximal margin.” Fleming. 
33. Lepralia,* Johnston. 
Character. Polypidom calcareous or membrano- calcareous, 
adnate , crustaceous , spreading circularly , formed of a layer of ur - 
ceolate cells in juxtaposition, horizontal ', and arranged in quin- 
cunx ; aperture terminal , often covered with an opercular ovary. 
—Polypes ascidian. 
* Margin of the aperture plain. 
1. B. hyalinAj 66 diaphanous , the cells forming an even smooth 
crust , with tubular simple mouths .” Rev. Dr Fleming.

Hob. “ On stones, shells, and corallines from deep water,” Fleming. 
“ The crust is semitransparent, the divisions of the narrow cells 
indicated by whitish lines, and the orifices are narrow, cylindrical, 
simple tubes, The crust is not circumscribed, otherwise it resembles 
the genus Discopora.” Dr Fleming. 
2. L. nitida, cells ovate , prominent , transversely ridged , or, 
when dry, fissured. Dr Fleming.

* Lepralia — “ sea-scurf” — derived from as^«, leprosy, and atA/o?, marine : 
an expressive name for the genus suggested by my friend, the Rev. Thomas 
Riddell. It is synonymous with the “ Berenicea” of Dr Fleming, but not of La- 
mouroux, and the name belongs of right to the latter ; — the more readily yield- 
ed up since we find a “ Berenicea” also amongst the Medusse. Milne-Edwards 
names the genus “ Escharo'ides,” but neither this nor Escharina, another of his 
names, can be adopted, since some naturalists use the terminations oide and ina 
as family appellatives. Moreover what saith Linnaeus? — “ Generic names includ- 
ing other generic names are unworthy of a scientific nomenclature.” And again 
— “ Generic names ending in oides are prohibited.” See Young’s Med. Litera- 
ture, p. 28.
