446 POLYPI. 
Ocuuna, Lam. 
The Oculinze have very short lateral ramusculi, giving them the 
appearance of having stars along the branches as well as at the 
ene, =, iu 
Mavrepora, Lam., 
Or his Madrepores proper, the whole surface is roughened by little 
stars with projecting edges}. 
In his Pocittopora we observe little impressed stars with pores-in 
the intervals f. 
In his Seriaropora, these little stars are disposed in linear 
ranges §. 
Astrea, Lam., 
A broad surface, usually convex and excavated by crowded stars, 
each containing a polypus furnished with numerous arms, but on a 
single range, in the centre of which is the mouth||. 
When it is a plane surface, or forms broad lamine covered with 
stars on one side, it becomes an Expnanaria®). 
The Porires are a sort of ramous Astrez **. 
When this surface is marked with elongated lines, like little valleys 
separated by transversely furrowed hills, we have the Mranprina, 
Lam. 
In each valley, and from space to space, we find mouths; and the 
tentacula, instead of forming rosettes round them, form a range along 
the sides of the valley. In some species they are totally wanting, the 
margin of each mouth being merely festooned +f. 
If the hills which separate these valleys are raised in leaves or 
crests, sulcated on both sides, it is a Pavonta. Mouths, usually 
without tentacula, are found at the bottom of the valleys tf. 
When these hills are conical or like projecting stars, we have the 
Hypwopnuora of Fischer, and the Monvicunaria of Lamarck. They 
should be distinguished according to the situation of their Polypi,
