260 ZOOPHYTES. 



The bottom of the fossae between the septa, is one-eighth or one-tenth 

 of an inch broad, and contains on either side of a central porous line, 

 a series of nearly square cellules alternating with the thin lamellae, of 

 which there are about seventeen to half an inch. The fossa? are 

 larger and more irregular, and the septa much stouter, than in the 

 interrupta.

 cequalibus, intermediis obsolescentibus ; fossis triangulatis ; fundo

Subhemispherical ; linear disks long, straight or flexuous in different 

 parts ; gyri 2 to 2 lines broad. Corallum cellular, firm ; ridges 

 nearly triangular; lamella? subacute, eroso-denticulate, remote, very 

 unequal, the intermediate smaller lamellae obsolescent ; fossae trian- 

 gular, lamello-linear at bottom, and not porous, with the longitu- 

 dinal lamella interrupted and somewhat crispate : in a transverse 

 section, septa J of a line thick.

The phrygia forms large convex masses, often a foot in diameter, 

 characterized by rather narrow gyri, with the lamellae lacerato-denti- 

 culate and triangular, the smaller obsolescent, and the larger remote, 

 leaving large intervals and cells between, of which there are ten or 

 twelve to half an inch. These characters give the corallum rather a 

 jagged surface. The lamella? project a little, and unequally, above 

 the septum, nearly as in the dedalea. The internal texture is rather 

 coarsely cellular.

 sented too thick, and the lamellae are Mad. jihgrana ? Gualtieri Ind. Test. tab.
