6. PORITES RECTA. (Lesueur.) 



P. cespitosa, 1-1 \" animata; ramis rectis, remotis, compressiusculis, di- 

 varicate fur catis, rotundatis ; polypis cylindricis salientibus, brunnes- 

 centibus; tentaculis brevibus. Corallum porosius, cellis parvulis, ex- 

 cavatis; radiis denticulatis. 



Cespitose, alive for 1 to 1J inches; branches straight, remote, some- 

 what compressed, divaricately furcate, rounded at summit; polyps 

 salient, cylindrical, tinged with brown ; tentacles short. Corallum 

 rather porous, the cells small, excavate ; rays denticulate. 



St. Bartholomew and St. Christopher's, West Indies. Lesueur. 



The above description is from Lesueur. He describes the species 

 as occurring in tranquil waters in the sand, from which it is easily 

 detached, and growing to a height of two or three inches. The 

 polyps are salient about their diameter above the cells. The summits 

 of the tentacles are white, with a semicircle of a deep sienna-brown. 

 It has smaller and less tortuous branches than the clavaria.

7. PORITES DIVARICATA. (Lesueur.) 



P. cespitosa, 1-1" animata ; ramis valde gracilibus (3-4'"), compressi- 

 usculis, divaricatis et flexuosis, interdum reflexis, apice rotundatis, 

 scepe fur catis. Corallum fragile ; cellis parvulis ("'), excavatis. 



Cespitose, alive for 1 to l inches; branches quite slender (3 to 4 lines 

 thick), somewhat compressed, divaricate and flexuous, sometimes 

 reflexed ; apex rounded, often furcate. Corallum fragile; cells 

 small (i a line broad), excavate. 



Guadaloupe, West Indies. Lesueur. 



This species is far more slender than either of the preceding, and 

 has a very divaricate and flexuous mode of branching. The furcate
