432 POLYPI. VAGINATI. 



F. limacina, Lam. (M. pileus, Lin.) Oblong, convex, concave, 

 and echinated below j stars elongated, lamellae unequal. Inha- 

 bits Indian seas. Ellis, Zooph. pi. 45. 



Gen. 26. CYCLOLITES, Lam. Madrepora, Lin. 

 Stony, free, orbicular, or elliptic, convex, and lamellar above, 

 hollow in the centre, flattened below, with circular concentric 

 lines ; a single lamellated star occupying the upper surface ; 

 the laminae very fine and entire. 



C. numismalis, Lam. {M. porpita, Lin.) Orbicular, a convex la- 

 mellar star above, hollow in the centre, rounded. Inhabits Indian 

 seas, and found fossil. Lam. ii. 233. 



Other fossil species of this genus have been found in France, &c. 



Gen. 27. TURBINOLIA, Lam. 



Polypiferous mass free, simple, turbinated or cuneiform, po ; nt- 

 ed at the base, striated longitudinally without, and terminat- 

 ed by a lamellated and stellular cell, sometimes oblong. 



The species of this genus are all fossil. 



Gen. 28. CARYOPHYLLTA, Lam. Madrepora, Lin. 

 Polypiferous mass stony, simple or branched, with the stem and 

 branches subturbinated, striated longitudinally, and each ter- 

 minated by a lamellar star-shaped cell. 



In some species the stem is simple, isolated, and with but one terminal star ; in 

 others it is fasciculated, or with a number of agglomerated stems, each terminated by 

 a stellated cell ; while in many others the stem is divided into branches, each branch 

 terminated in a stelliform cell. The stem and branches are cylindrical, sometimes 

 turbinated, and always striated longitudinally. The polypi are elongated, and fur- 

 nished each with eight plumose and radiated tentacula. 



* Stems simple, solitary or fasciculated. 



C. cyathus, Lam. Stem solitary, clavato-turbinate ; star concave, 

 the centre papillose. Inhabits Mediterranean sea. Ellis, Zooph. 

 pi. 28, fig. 7- 



C.fasciculata, Lam. Cylindrical, clavato-turbinate, longish, the la- 

 minae of the stars projecting. Inhabits Indian Ocean, and found 

 fossil in Europe. Ellis, Zooph. pi. 30. 



** Stems divided or branched. 



C.flexuosa, Lam. Stems cylindrical, branched, flexuose, in agglo- 

 merated rounded bundles. Inhabits Indian Ocean. Ellis, Zooph. 

 pi. 32, fig. 1. 



C. angulosa, Lam. Cespitose ; branches short, erect, thick ; stellae 

 orbicular, sinuous, irregular. American seas. Lam. ii. 229. 



Gen. 29. SARCINULA, ~Lam.Madrepora, Lin. 

 Stony, free, forming a polypiferous simple and thick mass, com- 

 posed of united tubes ; tubes numerous, cylindrical, parallel, 

 vertical, united in bundles by intermediate and transverse par- 

 titions ; radiated laminae in the interior of the tubes.
